• The thiophenic sulfur compounds in poly-aromatic fraction of Kuwait gas oil were analyzed by low voltage ionization method. The sulfur compounds which have the same mass number series with the aromatic hydrocarbons in the spectrum of low voltage ionization were separated by liquid chromatography and which could not be separated completely from the aromatic hydrocarbons were analyzed by distribution curve method. It became evident that this method is useful for the analysis of sulfur compounds under coexsistence of hydrocarbons. The abundance order of the thiophenic sulfur compounds were benzothiophenes, dibenzothiophenes, 2, 3 dihydro-benzothiophenes and tetra-hydro-di-benzothiophenes. The thiophenes were accounted as the biphenyls and their abundance is considered to be very small in gas oil fraction. The carbon number of alkyl side chain on the most abundant molecules of above four compound types were 6, 4, 5 and 3 respectively.
