Abstract: GS, a FCC gasoline sample, was first distilled into 6 cuts, and the detailed sulfur compositions present in each cut were analyzed using an Agilent 6890 gas chromatograph configured with an G2350A atomic emission detector (GC/AED). The data show that the sulfur compounds are mainly thiophenes and alkyl-substituted thiophenes, and the distribution of sulfur is not uniform, and a large part is concentrated in the heavy cut of the sample. The data can also be used to estimate the cut point between light and heavy cuts, which is helpful to remove sulfur effectively by different methods at lowest cost.
