“…Recent air pollution by diesel exhaust gas in the area of big cities has been one of the serious problems in the world, and much attention has been focused on deep de-sulfurization of light oil. The latest developments of analytical techniques have enabled the analysis of polyaromatic sulfur-containing compounds (PASC) such as alkylbenzothiophenes and alkyldibenzothiophenes which are considered to be key compounds of the hydrodesulfurization (HDS) of light oil (Martin and Grant, 1965; Drushel and Sommers, 1967;Later et al, 1981; Kong et al, 1984; Nishioka et al, 1985Nishioka et al, ,1986Reynolds and Biggs, 1987; Sughrue et al, 1988;Skelton et al, 1989; Bradley and Schiller, 1986;Miki et al, 1989). Although studies of HDS of thiophenes in naphth, white oil, light catalytic cycle oil, etc.…”

A study is carried out on chemical constitution of sulfur compounds in MTBE and their formation mechanisms. These sulfur compounds are classified into three types: common sulfur compounds, newly formed sulfur compounds, and high boiling sulfur compounds. Common sulfur compounds which include mercaptans, low molecule sulfides and disulfides, are directly from C4, one of the stocks for production of MTBE. The newly formed sulfur compounds, with one sulfur atom and five or more total carbon atoms in one molecule, are mainly tert-butyl methyl sulfide and tert-butyl ethyl sulfide, thioetherification products of thiols with butenes. Many high boiling sulfur compounds, including polysulfides such as dimethyl trisulfide, multisulfur heterocyclic compounds such as 3,5-dimethyl-1,2,4-trithiolane, and oxygen-containing sulfur compounds such as 2-methoxy-3-methylthiobutane, are also found newly formed in the processes of LPG refining and succedent etherification reaction for producing MTBE. Polysulfides are additional products of elemental sulfur to disulfides, and other high boiling sulfur compounds may be formed by thiols reacting with dienes.

“…Various approaches have been developed to address these needs for sulfur simulated distillation, e.g., by GC-AED (GC with atomic emission detection) [3], and flame photometric detection (FPD) coupled with a furnace to convert all sulfur compounds to SO 2 [4,5]. GC-AED is an extremely powerful technique, allowing the determination of several elemental chromatograms simultaneously.…”
