Application of a flame photometric detector to the gas chromatographic measurement of sulfur compounds in hydrocarbon fractions

Application of a flame photometric detector to the gas chromatographic measurement of sulfur compounds in hydrocarbon fractions. Baig, A. R.; Cowper, C. J.; Gibbons, P. A. 110-02-1 and 52006-63-0 are cas registry numbers. These chemicals are also mentioned in this article. (Br. Gas Corp., London SW6 2AD, UK). Chromatographia, 16, 297-300 (English) 1982. CODEN: CHRGB7. ISSN: 0009-5893. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 80 Anal. of individual S compds. in a complex hydrocarbon matrix is complicated either by quenching or by simultaneous hydrocarbon response. In the latter case, the hydrocarbon response can be subtracted by opposing the signals from 2 different detectors, leaving a simplified chromatogram of the S compds. The method was applied to the anal. of a desulfurized gas oil with and without the presence (at the ppm level) of added S compds. (i.e., thiophene [110-02-1], ethylthiophene [52006-63-0], benzothiophene [11095-43-5], and dibenzothiophene [132-65-0]). .

Desulfurization of gasolines

Desulfurization of gasolines.Several substances are used for example 52006-63-0 and 7631-86-9 which are their cas registry numbers.

DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) A process for prodn. of gasoline with a low S content from gasoline contg. thiophenic compds., olefins, and mercaptans includes (1) alkylation of the thiophenic compds. by olefins, (2) treatment of the effluent from the stage 1 under conditions of addn. of olefins to mercaptans, and (3) distn. of the effluent from the stage 2 to obtain a light fraction depleted of thiophenic compds. and mercaptans and a S-enriched heavy fraction. The latter may be (a) hydrotreated to decomp. the S compds. to hydrocarbons and H2S or (b) desulfurized by adsorption, oxidn., or solvent extn. Optionally, the charge is pretreated by selective hydrogenation or extn. The process is suitable for treatment of hydrocarbon fractions from catalytic cracking, coking, visbreaking, and pyrolysis. .
