An air pollution modeling study was conducted to investigate the odorous effects of volatile organic compounds (VOCs) emissions from a sanitary landfill area on ambient air quality. The atmospheric dispersion of hydrogen sulfide (H(2)S) and 22 VOCs was modeled. Industrial Source Complex v3 Short Term (ISCST3) model was used to estimate hourly concentrations of odorous VOCs over the nearest resi...

A set of chemical reactions is proposed to account for the formation of pantothenic acid derivatives from a primeval atmosphere composed of ammonia, formaldehyde, propyne, ethyne, hydrogen sulfide, hydrogen and water. Three precursor molecules are initially formed; a di-adduct of propyne and the catalyst Mg.porphin, azetidine2one, and 2-amino ethyl mercaptan. These then react sequentially to fo...

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 kinetic o...

This work proposed a gas sensor for the determination of tert-butyl mercaptan, one of the highly toxic volatile sulfur compounds, which was based on cataluminescence emission during its catalytic oxidation on the surface of nanosized V(2)O(5). The cataluminescence characteristics and the optimum conditions, including the morphology of sensing material, the wavelength of cataluminescence emissio...

Natural gas is odorized by trace amount of mercaptans and organic sulfides to be recognized by individuals, in case of gas leakage. These materials may pollute the environment particularly in injection station at local gas plants. Therefore, removal of sulfur compounds from the remaining odorant in barrels is essential. To remove the residual portion of mercaptans and alkylsulfide mixtures diff...
