【Abstract】 The method for separation and determination of sulfur compounds in fluid catalytic cracking gasoline by gas chromatography-atomic emission detector(GC-AED) was established. More than sixty sulfur compounds were quantified. The effects of speed of carrier gas, oven temperature on resolution and column effects were discussed. Retention indices of different sulfur compound in temperature programmed condition were calculated. External calibration curve was applied to the area responses of each sulfur components in the sulfur chromatogram, and the concentration of each was calculated. The contents of each sulfur compound in gasoline and desulfured gasoline were determined.更多还原
