The fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. Biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. Therefore, the production of petroleum-like fractions from nonedible oil e...

Mercaptans are commonly present in petroleum products. Their foul odor and highly corrosive nature make them the most undesirable sulfur compounds so they should be removed because of environmental issues. Merox process is used for oxidation of mercaptans to disulfide using air in the presence of alkaline solution and Merox catalyst. In this paper, due to lack of information about the kinet...

The purpose of this study is to determine whether gas chromatography (GC)-atomic emission detection (AED) can be used in a low-resolution mode for rapid, accurate determinations of total sulfur in fuels at trace levels to complement other popular methods of total sulfur analysis. A method for the rapid determination of total sulfur in fuels (called "fast GC-AED") is developed. The method is tes...

Biosurfactants are amphiphilic compounds produced by various bacteria and fungi which reduce surface and interfacial tension. Oil contaminated soil were collected from four different automobile shop in Mayiladuthurai, Tamilnadu, India. Bacillus subtilis and Pseudomonas aeruginosa were isolated and identified from these four samples and these were screened for biosurfactants production using veg...

Thermolysis of waste plastics in an inert atmosphere has been gazed at as a useful method, because this technique can convert waste plastics into hydrocarbons that can be used either as fuels or as other valued chemicals. In this work, waste polyethylene (PE) was chosen as the raw material for thermolysis. A well designed semi batch reactor has been used for thermolysis of waste polyethylene (P...

• Norisoprenoids are important compounds that contribute to the aroma of wines. Examples of norisoprenoids are ß-ionone and ß-damascenone , which contribute intense fruity aromas; TDN (trimethyldihydro-naphtalene), which contributes the typical kerosene, or petrol, note in wines (in high concentrations, TDN may be considered a defect); and actinidol and vitispirane , which contribute other comp...

β-SiC-supported cobalt catalysts have been prepared from nitrate, acetate, chloride and citrate salts to study the dependence of Fischer–Tropsch synthesis (FTS) on the type of precursor. Com/SiC catalysts were synthetized by vacuum-assisted impregnation while N2 adsorption/desorption, XRD, TEM, TPR, O2 pulses and acid/base titrations were used as characterization techniques. FTS catalytic perfo...

During production from oil wells, the deposition of asphaltene and wax at surface facilities porous media is one major operational challenges. The crude rate significantly reduced due to inside reservoir. In addition, these solids costly companies. this study, efficiency different solvents in dissolving was investigated through static dynamic tests. analysis solid deposits choke Iranian carbona...
