Full text

Abstract:

Polycyclic aromatic hydrocarbons (PAHs) are compounds containing carbon and hydrogen atoms of fused benzene rings in linear, angular or cluster arrangements. These compounds have a large (negative) resonance energy, resulting in a thermodynamically stable structures. PAHs may also contain alkyl- and nitro-substituent groups. The complexity in these molecules can be generated by substituting the aromatic carbon atom with nitrogen, oxygen or sulfur, giving rise to heterocyclic PAHs.

Abstract:

Neuroendocrine processes coordinate the behavioural, physiological, and seasonal aspects of reproduction. Some chemicals can disrupt the hypothalamus-pituitary-gonadal axis, impacting reproductive health. Naphthenic acids (NAs), the carboxylic acids in petroleum, are of emerging concern as they contaminate coastlines after oil spills and aquatic ecosystems of the Athabasca oil sands area. They are acutely toxic in fish and tadpoles and possibly endocrine disrupting at sublethal levels. I characterized courtship behaviours and disruption by NAs in the Western clawed frog, Silurana tropicalis. C

Abstract:

Naphthenic acids (NAs) are carboxylated alkanes and cycloalkanes concentrated in wastewater during oil sands processing. The general chemical formula is C{n}H{n+Z}O{2}, where n represents the number of carbon atoms and Z specifies a homologous family with 0-6 rings (Z=0 to Z=-12). The wastewater is acutely toxic to surface water organisms and is stored in tailings ponds with over 230 million m³ of fines tailings and free water. The purpose of this thesis was to provide a preliminary evaluation of the potential attenuation of NAs during groundwater flow from the ponds. Laboratory

Abstract:

The remediation of tailings water, a by-product of bitumen extraction, is of utmost importance to the Athabasca oil sands industry due to its toxicity to aquatic environments. Naphthenic acids (NAs), natural components of bitumen, are the major contributor to the toxicity of tailings water. The use of algae for remediation of tailings water is a new approach to reduce the toxicity of tailings water. The combined extracted NAs and algal oils can potentially be used as a low cost feedstock for the production of biodiesel. In this study, the feasibility of using NAs for the production of biodiese

Abstract:

Naphthenic acids are a family of carboxylic acids that are found in oil sands bitumen. These compounds partition to the aqueous phase during extraction and refining and are toxic to various biota. The removal of these acids from solution is difficult due to their low concentrations, complexity of the mixture and poor understanding of the behaviour of the mixed compounds. In particular, partitioning of these organic acids to solid surfaces is not well understood. Knowledge of this equilibria would be helpful for potential process development.

Abstract:

The sustained high price of crude oil is increasing the viability of producing oils and tarry bitumens which have high acid contents and which would have been uneconomical to produce previously. The acidity of these oils is due to the presence of a class of compounds known as Naphthenic Acids (NAs) which are thought to arise from the biodegradation of some of the crude oil hydrocarbons. Some oils contain as much as 3% by weight NAs. The acids cause engineering and production difficulties through corrosion of refinery plant and deposition as salts in pipelines. NAs also cause environmental prob

Abstract:

The recent increase in crude oil cost arose interest in cheaper oils, usually called “opportunity crudes”. These oils are difficult to transport and treat, mainly because of their sulphur content, acidity and high density, but their cheap price makes them attractive, because refineries capable of processing them could gain a higher profit. Opportunity crudes composition affects process parameters and they can also cause corrosion and failures in plant equipment. It is well known that the main corrosive agents are the naphthenic acids (NAs), but the mechanism is complex and very little is know

Biocatalysis involves the use of enzymes to perform stereo- and enantio-specific reactions. One of the reactions where biocatalysis is a valuable technology is oxidation of naphthalene to 1-naphthol using Toluene ortho-Monooxygenase (TOM) variant TmoA3 V106A, also known as TOM-Green. Whole-cell biocatalysis in a water-organic solvent biphasic system was used to minimize naphthalene and 1-naphthol toxicity, and to increase substrate loading. Recombinant Escherichia coli TG1 cells expressing TOM-Green were used for biphasic biocatalysis and lauryl acetate gave best results among the solvents tes

Abstract:

Thienoacenes represent an intriguing class of organic semiconducting molecules with potential applications in organic electronics. Some of thienoacenes have been reported with high charge carrier mobility in organic field-effect transistors (OFET). OFETs based on naphtho[2,1-b:3,4-b’]dithiophene (NDT) exhibited moderate device performance and low-band gap donor-acceptor copolymers based on NDT showed a promising solar power conversion efficiency. In this thesis, four novel series of thienoacenes based on naphtho[2,1-b:3,4-b’]dithiophene backbone were designed and synthesized for OFET applicat

Abstract:

碩士<br>長庚大學<br>化工與材料工程研究所<br>94<br>Distillative Freezing process (hereinafter called DF process) is a new separation technique. Basically, DF is operated at triple point condition, in which the liquid mixture is simultaneously vaporized and solidified due to the three-phase equilibrium. It results in the formation of pure solid and liquid phase and vapor phase of mixtures. As the DF process is conducted under an adiabatic condition, the latent heat released in forming the solid crystals is mostly removed by vaporizing portions of liquid mixtures. The process is continued until the liquid phase
