Abstract:
Aromatic hydrocarbons like naphthalene are common environmental pollutants of petrochemical waste. Microorganisms have been exploited since long back to clean up such pollutants by converting them in to either non- toxic or less toxic aromatic or aliphatic compounds. A bacterial strain have been isolated from oil sludge of Guwahati Refinery, Assam and was identified as Staphylococcus pasteuri RD2 (NCBI accession number MG680735) through 16srDNA sequence analysis and molecular phylogeny. The bacterial strain transforms Naphthalene, a common hazardous aromatic hydrocarbon found in petrochemical waste, into a number of less hazardous aliphatic hydrocarbons. Detection of compounds such as Decane, Dodecane, tetradecane, Hexadecane, Eicosane, and heptane by GC-MS analysis of naphthalene enrichment culture broth suggested that the bacterial strain was able to transform naphthalene in to different aliphatic hydrocarbons with less toxicity and having chain length of C7 to C20. It has also been depicted a pathway to obtain aliphatic hydrocarbons with higher caloric value from aromatic hydrocarbon waste.

Abstract:
Ten bacterial strains were isolated by enrichment culture, using as carbon sources either aliphatics or an aromatic–polar mixture. Oxygen uptake rate was used as a criterion to determine culture transfer timing at each enrichment stage. Biodegradation of aliphatics (10 000 mg L–1) and an aromatic–polar mixture (5000 mg L–1, 2:1) was evaluated for each of the bacterial strains and for a defined culture made up with a standardized mixture of the isolated strains. Degradation of total hydrocarbons (10 000 mg L–1) was also determined for the defined mixed culture. Five bacterial strains were able to degrade more than 50% of the aliphatic fraction. The most extensive biodegradation (74%) was obtained with strain Bs 9A, while strains Ps 2AP and UAM 10AP were able to degrade up to 15% of the aromatic–polar mixture. The defined mixed culture degraded 47% of the aliphatics and 6% of the aromatic–polar mixture. The defined mixed culture was able to degrade about 40% of the aliphatic fraction and 26% of the aromatic fraction when grown in the presence of total hydrocarbons, while these microorganisms did not consume the polar hydrocarbons fraction. The proposed strategy that combines enrichment culture together with oxygen uptake rate allowed the isolation of bacterial strains that are able to degrade specific hydrocarbons fractions at high consumption rates.Key words: biodegradation, defined mixed culture, enrichment culture, hydrocarbon fractions, oxygen uptake.

Abstract:
The continuous research on anthropogenized coastal zones determined qualitative and quantitative characteristics of aliphatic hydrocarbons in the Curonian Lagoon and the Nemunas River Delta. The concentration of aliphatic hydrocarbons varied from 9.1 to 187.6 μg g−1 d.w. The Curonian Lagoon could be classified as a slightly contaminated water basin with some moderately polluted areas, while both rivers and Lake Krokų Lanka were found to be slightly contaminated with aliphatic hydrocarbons. The prevailing unresolved complex mixture and geochemical markers suggested the existence of mixed biogenic-anthropogenic aliphatic hydrocarbon sources in the area studied. The biogenic impact was found to be more pronounced in Lake Krokų Lanka, the south-eastern part of the Curonian Lagoon and in the River Minija, while the Nemunas River Avandelta demonstrated the highest loading of anthropogenic hydrocarbons. The same trends were confirmed by the principal component analysis.

Abstract:
Abstract. Surface sediments collected from deep basins (22 stations, 1018–4087 m depth) of the Eastern Mediterranean Sea (EMS) were analyzed for aliphatic, triterpenoid and polycyclic aromatic hydrocarbons (PAHs) as tracers of natural and anthropogenic inputs. Concentrations of total aliphatic hydrocarbons (TAHC), n-alkanes (NA) and the Unresolved Complex Mixture (UCM) of aliphatic hydrocarbons ranged from 1.34 to 49.2 µg g−1, 145 to 4810 ng g−1 and 0.73 to 36.7 µg g−1, respectively, while total PAHs (TPAH25) concentrations ranged from 11.6 to 223 ng g−1. Molecular profiles of aliphatic hydrocarbons and PAHs reflect the contribution of both natural (epicuticular plant waxes) and anthropogenic (degraded petroleum products, unburned fossil fuels and combustion of petroleum, grass, wood and coal) compounds in deep EMS sediments, with hydrocarbon mixtures displaying significant regional variability. Hydrocarbon concentrations correlated significantly with the Total Organic Carbon (TOC) content of sediments, indicating that organic carbon exerts an important control on their transport and fate in the study area, while strong sub-basin and mesoscale variability of water masses also impact their regional characteristics. Major findings of this study support that deep basins/canyons of the EMS could act as traps of both natural and anthropogenic hydrocarbons.

Abstract:
Sixty-four species of filamentous fungi from five flare pits in northern and western Canada were tested for their ability to degrade crude oil using gas chromatographic analysis of residual hydrocarbons following incubation. Nine isolates were tested further using radiorespirometry to determine the extent of mineralization of model radiolabelled aliphatic and aromatic hydrocarbons dissolved in crude oil. Hydrocarbon biodegradation capability was observed in species representing six orders of the Ascomycota. Gas chromatography indicated that species capable of hydrocarbon degradation attacked compounds within the aliphatic fraction of crude oil, n-C12- n-C26; degradation of compounds within the aromatic fraction was not observed. Radiorespirometry, using n-[1-14C]hexadecane and [9-14C]phenanthrene, confirmed the gas chromatographic results and verified that aliphatic compounds were being mineralized, not simply transformed to intermediate metabolites. This study shows that filamentous fungi may play an integral role in the in situ biodegradation of aliphatic pollutants in flare pit soils.Key words: bioremediation, filamentous fungi, flare pits, hydrocarbon degradation, petroleum.

Abstract:
Here, we report the results of petroleum component contamination assessment of the Temernik river and the Don river. Our aim was to study the hydrocarbon group content of petroleum components in the river water. Thus, we determined the mass concentrations of chemical oxygen demand, petroleum components, and aliphatic and polycyclic aromatic hydrocarbons. In the Temernik river, the concentrations of chemical oxygen demand, petroleum components, sum of aliphatic and polycyclic aromatic hydrocarbons were 21.4–34.4 mg/L, 0.14–6.0 mg/L, 10–18 μg/L, and 0.17–2.9 μg/L, respectively. The concentrations of chemical oxygen demand, petroleum components, and benzo[a]pyrene exceeded the maximum permissible concentration by 1.4–2.3, 2.8-120, and 1.3–5.8 times, respectively. In the Don river, the concentrations of chemical oxygen demand, petroleum components, sum of aliphatic and polycyclic aromatic hydrocarbons were 18.7-29.5 mg/L, 0.08- 0.16 mg/L, 8.2-12 μg/L, and 0.03-0.13 μg/L, respectively. The Severnoe reservoir was the less contaminated part of the river. The Temernik river estuary was the most contaminated part of the river. The pollutant concentrations increased in the Don River downstream of the Temernik river estuary. Therefore, the Temernik river influences on the Don river contamination. The chemical oxygen demand, petroleum components, and polycyclic aromatic hydrocarbons had the close distribution of concentrations in the rivers. However, the aliphatic hydrocarbon concentration changed in another way. The results of the study showed that the hydrocarbon groups of petroleum components can have different sources.

Abstract:
AbstractThe Spitzer Space Telescope has discovered several objects with unusual spectra, where the emission features from polycyclic aromatic hydrocarbons (PAHs) are shifted to longer wavelengths than normally observed. Previously, only two of these class C PAH spectra had been identified. The new and larger sample reveals that PAHs emit at longer wavelengths when processed by cooler radiation fields. Limited laboratory data show that samples with mixtures of aromatic and aliphatic hydrocarbons produce emission features at longer wavelengths than purely aromatic samples. The aliphatic bonds are more fragile and would only survive in cooler radiation fields. In harsher radiation fields, the aliphatics attached to the aromatic hydrocarbons are destroyed.

AbstractThe emitted aliphatic hydrocarbon profile of four Indian Coccinellidae (Coleoptera), Coccinella septempunctata (Linnaeus) (C7), Coccinella transversalis Fabricius (Ct), Menochilus sexmaculatus (Fabricius) (Ms), and Propylea dissecta (Mulsant) (Pd) has been investigated by simple solvent-less headspace solid-phase microextraction (HS-SPME) technique coupled with gas chromatography and mass spectroscopy (GC-MS). Identified volatile and non-volatile compounds were confirmed by running corresponding standards and comparing with the National Institute of Standards and Technology library. Among the 56 identified aliphatic hydrocarbons, saturated aliphatic hydrocarbons were more in number than unsaturated ones. Among saturated hydrocarbons, methyl branched hydrocarbons were more in number in C7 and Ct than Ms and Pd. Menochilus sexmaculatus and Pd had higher percentages of unsaturated hydrocarbons than C7 and Ct. Among branched chain-hydrocarbons, mono-methylated saturated hydrocarbons were more in number than dimethylated saturated hydrocarbons. Further analysis of the semiochemical profile revealed a closeness between C7 and Ct, and between Ms and Pd. Quantitative analysis revealed that straight chain hydrocarbons form separate clusters to branched chain methylated hydrocarbons. This is the first attempt to identify the semiochemical profile of some Indian coccinellids using the headspace solid phase micro-extraction technique coupled with the gas chromatography-mass spectrometry technique. This report will be helpful for various chemotaxonomic studies of the species in the future.

Abstract. Surface sediments collected from deep basins (1018–4087 m depth) of the eastern Mediterranean Sea (Ionian Sea, southern Aegean Sea and northwestern Levantine Sea) were analyzed for aliphatic and polycyclic aromatic hydrocarbons as tracers of natural and anthropogenic inputs. Concentrations of total aliphatic hydrocarbons, n-alkanes and the unresolved complex mixture (UCM) of aliphatic hydrocarbons varied significantly, ranging from 1.34 to 49.2 μg g−1, 145 to 4810 ng g−1 and 0.73 to 36.7 μg g−1, respectively, while concentrations of total polycyclic aromatic hydrocarbons (PAHs) ranged between 11.6 and 223 ng g−1. Molecular profiles of determined hydrocarbons reflect a mixed contribution from both natural and anthropogenic sources in deep-sea sediments of the eastern Mediterranean Sea, i.e., terrestrial plant waxes, degraded petroleum products, unburned fossil fuels and combustion of grass, wood and coal. Hydrocarbon mixtures display significant variability amongst sub-regions, reflecting differences in the relative importance of inputs from various sources and phase associations/transport pathways of individual hydrocarbons that impact on their overall distribution and fate. Hydrocarbon concentrations correlated significantly with the organic carbon content of sediments, indicating that the latter exerts an important control on their transport and ultimate accumulation in deep basins. Additionally, water masses' circulation characteristics also seem to influence the regional features and distribution patterns of hydrocarbons. Our findings highlight the role of deep basins/canyons as repositories of both natural and anthropogenic chemical species.

Abstract:
Bioremediation of chlorinated aliphatic hydrocarbon (CAH) compounds commonly found at contaminated sites has been an area of focus in recent years. The cometabolic transformation of CAH compounds is important at sites where the redox condition does not favor natural attenuation or populations of indigenous microorganisms are relatively low. At sites where the ground-water system is aerobic, monitored natural attenuation strategies will not meet remediation objectives, or both, enhanced bioremediation via cometabolism is an option. Models are needed to simulate cometabolism in an effort to improve performance and design. The SEAM3D Cometabolism Package was designed to address this need. The objective of this report is to model field data to determine the ability of SEAM3D to simulate the performance of cometabolism. A ground-water flow and transport model was designed based on reported parameters used in the field experiments at Moffett Field. Electron donor and acceptor breakthrough curves were also simulated in an effort to calibrate the model. Several data sets describing the cometabolism of CAHs were used in the cometabolism modeling for calibration to field data. The cometabolism modeling showed areas of best fit calibration with modification to the model parameters reported for the pilot tests at Moffett Field. The overall performance of the SEAM3D Cometabolism Package described in this report establishes validation of the model using field experiment results from the literature. Additional model validation is recommended for other contaminants.

Abstract:
This dissertation examines the applicability of the iron-based degradative solidification/stabilization (DS/S-Fe(II)) to various chlorinated aliphatic hydrocarbons (CAHs) that are common chemicals of concern at contaminated sites. The research focuses on the transformation of 1,1,1-trichloroethane (1,1,1-TCA), 1,1,2,2-tetrachloro-ethane (1,1,2,2-TetCA) and 1,2-dichloroehtane (1,2-DCA) by Fe(II) in cement slurries. It also investigates the degradation of 1,1,1-TCA by a mixture of Fe(II), cement and three iron-bearing phyllosilicates. Transformation of 1,1,1-TCA and 1,1,2,2-TetCA by Fe(II) in 10% cement slurries was characterized using batch reactors. Dechlorination kinetics of 1,1,1-TCA and TCE* (TCE that was produced by transformation of 1,1,2,2-TetCA) was strongly dependent on Fe(II) dose, pH and initial target organic concentration. Degradation of target organics in DS/S-Fe(II) process was generally described by a pseudo-first-order rate law. However, saturation relationships between the rate constants and Fe(II) dose or between the initial degradation rates and target organic concentration were observed. These behaviors were properly described by a modified Langmuir-Hinshelwood kinetic model. This supports the working hypothesis of this research that reductive dechlorination of chlorinated ethanes occurs on the surface of active solids formed in mixtures of Fe(II) and cement. Transformation products for 1,1,1-TCA and 1,1,2,2-TetCA in mixtures of Fe(II) and cement were identified. The major product of the degradation of 1,1,1-TCA was 1,1-DCA, which indicates that the reaction followed a hydrogenolysis pathway. However, a small amount of ethane was also observed. TCE* was rapidly produced by degradation of 1,1,2,2-TetCA and is expected to undergo β-elimination to produce acetylene. Dechlorination of 1,1,1-TCA in suspension of Fe(II), cement and three soil minerals (biotite, vermiculite, montmorillonite) was characterized using batch reactors. A first-order rate model was generally used to describe the dechlorination kinetics of 1,1,1-TCA in this heterogeneous system. The rate constants for 1,1,1-TCA in mixtures of Fe(II), cement and soil minerals were influenced by soil mineral types, Fe(II) dose and the mass ratio of cement to soil mineral. It was demonstrated that structural Fe(II) and surface-bound Fe(II) in the soil minerals affect dechlorination kinetics and the effects vary with mineral types. Furthermore, it suggests that the reductant formed from Fe(II) and cement hydration components is also effective in systems that include soil minerals.

Main feature of fullerenization process is, that its products are formed in all volume of reactionary space, but are located (are deposited and are condensed) in it a low-temperature zone. Extracted from pyrolytic soot the products of benzene and nhexane fullerenization contain the condensed molecules containing up to 4.8 and 5.1 % of hydrogen accordingly, which allocation at thermolysis is began with 50ºС and proceeds up to 750ºС. Products of benzene and n-hexane fullerenization can be perspective for hydrogen storage.

Mineral oil is a by-product derived from petroleum distillation, applicable in the areas of cosmetics, pharmaceuticals and food, used as food additive when in the proper grade of purity for this propose. However, it can also be considered a contaminant, especially important in sunflower oil, due to the episode of the 100.000 tons of highly contaminated Ukrainian sunflower oil. This experimental work aims at implementing a method for the determination of saturated aliphatic hydrocarbons in sunflower oil by capillary gas chromatography with on column injection and FID detector. For such purpose parameters like linearity, working range, thresholds, precision, accuracy and robustness of the method were evaluated. The results show that the method is linear in the range between 15 and 60 mg.kg-1, with a repeatability limit of 6,11 mg.kg-1 and a variability of results obtained by this method of 0,48 mg.kg-1. The method allows to detect and quantify the analyte from 21 mg.kg-1 and 24 mg.kg-1, respectively. Considering the results obtained in recovery tests and Z-score of 0,5 and 0,04 obtained in inter-laboratory tests, the method is accurate. The robustness of this method is also verified, although it is sensible to the way the integration is performed

Abstract:
The results of the study at hand may have implications for treatment of grease, lipid fractions, free fatty acids (FFA) and salts of FFA extracted from wastes of food industry, bio-refineries or sewage sludge as well as contaminated lipid containing forage. The goal of the study is, to prevent such contaminated wastes from entering the food chain. The following ways of treatment are proposed. Thermal conversion of waste fats from rendering plants or lipids in the presence of aluminosilicates of the zeolite family produce hydrocarbons with net calorific values in the range of 40–42 MJ/kg. NMR studies show aliphatic hydrocarbons as main product at T = 400°C. The spectrum of products is shifted to alkyl benzenes at T = 550°C. In case of sodium carbonate conversion is achieved in the presence of 5% water at T = 430 ± 20°C yielding mainly a liquid bio-crude with a low acid index, a mixture of non-condensable gases and minor amounts of coke. Rectification of bio-crude from animal fat produces 65.8% of hydrocarbon based bio-diesel and 13.3% of gasoline type hydrocarbons. Distillation curve for bio-diesel is in accordance with DIN EN 490. However, the gasoline fraction lacks low boiling hydrocarbons indicating the necessity for technical improvements of condensers. Sodium carbonate is found to be effective as well as being relatively inexpensive compared to zeolite catalysts. Finally, successful conversion of meat and bone meal to biochar is proved by solid-state 13C-NMR.

Abstract:
The analysis of the main impacts on the environment during the construction of a mining and processing complex in Petrikov was carried out. The analysis showed that the most significant impact was on atmospheric air and groundwater. The scattering calculation showed that the greatest influence was exerted by nitrogen (II) oxide, nitric acid, potassium chloride, carbon oxide, unsaturated hydrocarbons, saturated aliphatic hydrocarbons C1-C10. The volume of surface runoff and the volume of chloride removal from the industrial site in the event of an emergency were also calculated. As water protection measures, complete isolation of the surface of the sites was envisaged, as well as the installation of a canal-water conduit with further purification of the drain and its use in the technological scheme provided for the operation of the mining enterprise.

Abstract:
Microwave torrefaction of corn stover with particle size of 4 mm was investigated and the effects of reaction temperature and time on the yields of volatile, bio-oil and torrefied biomass were determined. The response surface analysis of the central composite design (CCD) showed that the yields of volatile, bio-oil and torrefied biomass were significantly affected by the reaction temperature and time. Three linear models were developed to predict the yields of conversion products as a function of temperature and time. A first order reaction kinetics was also developed to model the corn stover torrefaction. Ph values of torrefaction bio-oils ranged from 2.3 to 2.76 which were similar to those of bio-oils from biomass pyrolysis. GC/MS analysis for torrefaction bio-oils showed that the organic acid was about 2.16% to 12.00%. The torrefaction bio-oils also contain valuable chemical compounds such as phenols, furan derivatives and aliphatic hydrocarbons determined by a GC/MS. There are no aromatic compounds and polycyclic aromatic hydrocarbons (PAHs) detected in the torrefaction bio-oils. The torrefaction biogas was mainly consisted of ch4, c2h6, c3h8, which was about 56 wt% of the total bio-gas. The biogas can be used for chemical synthesis or electricity generation. The heating values of torrefied biomass were from 18.64–22.22 MJ/kg depending on the process conditions. The heating values of torrefied biomass were significantly greater than those of raw biomass and similar to those of coals. The energy yields of torrefied biomass from 87.03–97.87% implied that most energy was retained in the torrefied biomass. Economic analysis indicated that the biomass microwave torrefaction plant located in a farm is profitable.

Abstract:
Abstract Carbon dioxide (CO2) injection is a well-known EOR-method to reduce residual oil in the pore network of oil reservoirs. It is also increasingly used as a means of mitigating the greenhouse gas emissions problem by storing it in geological formations. A key parameter to such attempts is the density of the rich CO2 mixture, which is formed downhole in the injection well, since it affects the swelling potential, oil formation volume factor, viscosity, hydrostatic gradient, fluid distribution and formation pore pressure. The density of the crude oil-CO2 mixture depends on the pressure-temperature conditions, the CO2 concentration and the dominant hydrogen compounds in the crude oil, i.e. whether they are aliphatics, aromatics, or naphtenics (cyclic structures). The PVT properties of the different CO2-hydrocarbon mixtures vary greatly and the available experimental data for tuning PVT simulators are scarce, especially for ternary mixtures at high pressures and CO2 concentrations. This study investigates the effect of CO2 concentration on the density of ternary mixtures containing CO2, methane, and a pure liquid hydrocarbon, which is either an alkane, aromatic or cycloalkane compound. The liquid hydrocarbons used in the study were normal heptane (n-C7), toluene (Tol) and cyclohexane (c-C6). The measurements were conducted at variable compositions, at temperatures of 50, 70, and 90 °C, and at pressures ranging between 100 and 517 bar. The ternary mixtures were: Methane, toluene and CO2 at 1:1 molar ratio and CO2 concentrations of 14%, 27% and 72%, Methane, cyclohexane and CO2 at 1:1 molar ratio and CO2 concentrations of 19%, 47% and 68%. Methane, n-heptane and CO2 at constant molar hydrocarbon ratio (C1/n-C7) of 2:1 and varying CO2 concentrations of 23% and 75%, Some of the rich CO2 mixtures exhibited retrograde condensation behaviour at high temperatures. The results were compared against predictions from an EoS model (Peng Robinson Equation of State), coupled with volume shift parameters. The comparison between the simulation calculations and the experimental data indicated good agreement in the densities, but significant deviations in the boiling point pressures (Pb). As a result, the EoS model can be safely used to predict the CO2 mass storage potential of reservoirs of known pore volume such as the depleted ones.

Abstract:
This paper discusses the traditional retouching method of egg tempera, which, amongst other retouching techniques, remains a practised and taught method at the Hamilton Kerr Institute (HKI), University of Cambridge, UK. Since its introduction to Britain, the method has evolved and adapted, most recently owing to the absence of MS2A resin. Laropal A81 has been used as the replacement isolating varnish. However, the physical properties and handling differ from MS2A. The typical diluent used at the HKI for Laropal A81 varnish is a 50:50 mixture of Shellsol A100 and Shellsol D40, however, when used as the isolating resin over an area of retouching this mixture could disrupt lower tempera layers. To remedy this, the diluent was changed to cyclococtane, an aliphatic hydrocarbon. Cyclooctane benefits from being less toxic compared to the aromatic hydrocarbon Shellsol A100 and can be manipulated more on the surface before the activation of lower Laropal A81 layers becomes problematic. Laropal A81 solubilized in cyclooctane was successfully used as the isolating resin for egg tempera retouching and offers promise for a variety of varnishing scenarios and retouching. This paper demonstrates this adapted method of egg tempera retouching through a case study of a 16th-century panel painting with large losses perfectly suited to this method.

Full text
Abstract:
Abstract Asphaltene deposits are considered one of the most common issues facing oil fields with low particle stability that can result in loss of well potential, jeopardize wellbore accessibility and cause premature electrical submersible pump (ESP) failures. Traditionally, these deposits are treated with hydrocarbon based solvents, which have low flashpoints, making them hazardous and expensive. The objective of this paper is to provide a comprehensive solution to effectively remove asphaltene and sand fill accumulation that forms in the near wellbore region. This paper will also provide a computational analysis to accurately predict asphaltene precipitation during the production phase for optimized inhibition process. A laboratory approach was implemented to test the effectiveness of different water based solvent types, including aromatic, aliphatic and heteroatom instead of the commonly used hydrocarbon solvents such as xylene to dissolve asphaltene samples collected from the field and placed under anaerobic conditions. A thorough evaluation of fundamental asphaltene properties, including saturates, aromatics, resins and onset pressure, is incorporated into a computational model to understand and accurately predict asphaltene precipitation behavior. The newly developed system offers significant advantages compared to the traditional system in terms of treatment effectiveness, deployment cost and health, safety, and environment (HSE) due to its relatively high flashpoint. The new system utilizes a water based solvent that leaves the formation in a water wet state instead of oil wet, thus creating a barrier layer that will delay asphaltene accumulation and reduce treatment frequency. Field implementation and post-job results utilizing this newly developed water based aromatic solvent will be discussed, including treatment effectiveness to dissolve downhole asphaltene accumulations. Asphaltene inhibition programs have been implemented based on the results acquired from this model and frequent inspection conducted showed no asphaltene deposition over extended production periods. This paper provides a laboratory proven and field tested water based aromatic solvent that is effective in dissolving asphaltene accumulations resulting in improved well potential while reducing the frequency of required treatments thus maximizing productivity. This system is unique as it provides a high flashpoint water/solvent mixture with solvency power often greater than xylene with the additional benefit of leaving the formation strongly water-wet. The developed computational model helped to reduce the treatment frequency resulting in reduced expenses and sustained production.
