摘　　要：采用毛细管气相色谱/脉冲火焰光度检测器(GC/PFPD)对催化裂化汽油中大部分硫化物做了定量和定性研究。在此基础上,考察了降硫助剂与平衡剂掺混后的使用性能,并采用GC/PFPD对产物FCC汽油中硫化合物进行了分析测定,结果表明降硫助剂的加入使FCC汽油硫含量显著下降。A capillary, gas chromatography combined with a pulsed flame photometric detector（GC - PFPD） was used for the qualitative and quantitative analyses of sulfur compounds in FCC gasoline, The performance of an FCC additive for naphtha sulfur reduction was investigated, and sulfur compounds in FCC gasoline were ana- lyzed by GC - PFPD. The results showed that the sulfur content of FCC gasoline was substantially reduced,
