Abstract:

Research on compounds from liquid smoke resulting from the pyrolysis of used tire waste has been conducted. The results of tire pyrolysis produce liquid hydrocarbons and charcoal which can be utilized and developed into more useful materials or finished goods. This study aims to identify the compound components of liquid smoke resulting from the pyrolysis of used tire waste. The research begins with manufacturing a pyrolysis tool based on the principle of dry distillation. The pyrolysis process is carried out by heating at high temperatures. Liquid smoke analysis was carried out using GC-MS. I

Abstract:

Pyrolysis is one of thermochemical conversion to convert biomass into bio-oil. The higher energy content in bio-oil suggests its potential as a raw material in the production of energy, bio-fuels, and other chemicals. Pyrolysis of PKS and the chemicals released were studied using pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) at 400-600°C. Prior to pyrolysis, thermogravimetry experiments were carried out to monitor the degradation temperature of hemicellulose, cellulose, and lignin in the PKS. Degradation of hemicellulose occurred within a temperature range of 150-330°C, whereas the

Abstract:

Abstract Indonesia is the highest CPO producer globally, but CPO production also produces waste. The highest waste in CPO production is empty fruit bunch (EFB) (±58.3%). EFB is biomass waste that has the highest lignocellulose compound. Lignocellulose compound could utilize by conversion with physical, chemical, and biological degradation. Pyrolysis is one of the physical methods to degrade the lignocellulose compound. This research aimed to determine bioactive compounds produced from EFB pyrolysis.

Microplastics have become a ubiquitous contaminant in the environment. The present study focuses on the identification, characterization, and quantification techniques for tracking microplastics.

Pathogenic fungi, along with fires and insect pests, are among the most important factors affecting coniferous forests in Siberia. Conifers are attacked by fungi that cause stains and decay of wood. The decrease in quality and timber loss due to stain and decay caused by fungi can be significant. The early detection of fungi in wood allows taking preventive measures to reduce the potential threats caused by fungi in the forests. The mycelia of brown-rot (Fomitopsis betulina, Phaeolus schweinitzii) and white-rot (Trametes versicolor, Phellinus chrysoloma) fungi and mycelia extracts were studied

Abstract:

Identification and assessment of phenol and phenolic rich components of heavy oil fractions of biomass pyrolytic oil were conducted. The original bio-oil used for this study was derived from the pyrolysis of empty fruit bunch (EFB). It was separated into water soluble (light oil) and water insoluble (heavy oil) components by mixing it with water at 2:1 V/V ratio under ambient condition with vigorous stirring using centrifuge for 30mins. The raw bio-oil and the heavy oil fractions were later characterized using Fourier Transform Infra-Red (FTIR) and Gas chromatography-Mass spectroscopy (GC-MS)

Abstract:

Waste tires represent a disposal problem, environmental problem. To solve this problem and to upgrade this waste, several technologies are adopted such as pyrolysis. This technology produces a liquid that could replace other fuels. In this paper an experimental investigation is carried out to study the effect of the catalysts on biofuel. Two different percentages of catalysts have been used i.e. 10% and 20%. Experiments were carried out in a semi-batch reactor under atmospheric pressure. The properties of the products measured are the viscosity, the gross calorific value and the acid value. Id

Abstract:

In order to better utilize and recover the productive waste leaves from the Cinnamomum camphora, pyrolysis- GC/MS technology was used to analyze the possible top value-added components of benzene/ethanol extractives of Cinnamomum camphora leaves. Relative content of each component was determined by area normalization. 95 compounds from 102 peaks representing 99.216% of the benzene/ethanol extractives of Cinnamomum camphora leaves were identified, and the main constituents were Hexadecanoic acid, 4-nitrophenyl ester (17.336%), Vitamin E (4.804%), Oxirane, hexadecyl- (4.639%), 2,6-Bis(3,4-methyl

Abstract:

Plastic-waste pyrolysis oils contain large amounts of linear, branched, and di-olefinic compounds. This makes it not obvious to determine the detailed group-type composition in particular to the presence of substantial amounts of N-, S-, and O-containing heteroatomic compounds. The thorough evaluation of different column combinations for two-dimensional gas chromatography (GC × GC), i.e., non-polar × polar and polar × non-polar, revealed that the second combination had the best performance, as indicated by the bi-dimensional resolution of the selected key compounds. By coupling the GC × GC to

Abstract:

Research on the sources of microplastics (MP) in the environment and the parameters that lead to the loss of microfibers from synthetic textiles during washing have recently attracted public attention. Considering the involvement of a variety of structural and process parameters, it is important to choose methods for quantifying fibers as MP pollutants that migrated during the washing process. In the research to date, various sampling techniques and analytical protocols for the identification of polymers from washed synthetic textiles have been applied.

Abstract:

Important features required for gels used for the cleaning of paintings are viscoelastic properties ensuring good adaptability to the morphology of the surfaces and complete gel removal after application. Poly (vinyl alcohol) (PVA)-borax gels containing different liquid phases are often used as cleaning materials, but still little is known about their ability to leave no residues. This study reports the development of an analytical method based on attenuated total reflectance–Fourier transform infrared (ATR-FTIR) spectroscopy and pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) for th

Abstract:

To investigate the catalytic pyrolysis performance of complex metal oxide catalysts for biomass, γ-Al2O3 was prepared through the precipitation method, and then ZrO2 and γ-Al2O3 were blended in the proportion of 2:8 using the co-precipitation method. Next, CeO2 was loaded on the surface of the catalyst for further modification. The three catalysts, A, ZA and CZA, were obtained. The specific surface and acidity of the catalysts were characterized by nitrogen adsorption–desorption and NH3-Temperature Programmed Desorption (NH3-TPD) respectively.

The bamboo resource is very abundant in China, and both species and yield of bamboo are the first in the world. In the countryside of China, farmers often used the extractives of bamboo root to cure some special diseases; however, the biomedical constituents of extractives of bamboo root are still not completely explained. Therefore, 450 °C pyrolysis- GC/MS technology was used to identify the top value-added biomedical constituents of root-based benzene/ethanol extractives from the richest bamboo species “Moso bamboo”. After treatment of benzene/ethanol extraction, the extractives obtained was

Abstract:

Arson is defined as any intentional or deliberate burning of property. This malicious intent is not only confined within the realms of destruction of property but also of destruction of evidences present at the scene of crime or to commit a crime. Hence, it is necessary to know - the cause of fire, identification and collection of evidences. Usually accelerants such as kerosene, diesel, etc. are used to set or accelerate the rate of burning. These liquids are used because they have low boiling points which will help in accelerating the rate of fire and thus, the main aim of

Abstract:

Microplastics are harmful to both marine life and humans. Herein, a pyrolysis–gas chromatography–mass spectrometry (Py-GC/MS) technique for the detection of microplastics in aquatic shellfish is demonstrated. The organic matter in aquatic shellfish was removed by alkali digestion. Subsequently, using hexafluoroisopropanol as the extraction solvent, the extraction method was optimized. The influence of the digestion process on the nature of microplastics was investigated by analyzing the samples before and after the alkali treatment via infrared spectrometry, laser particle sizing, and scanning
