| 摘 要： | 将气相色谱-脉冲火焰光度检测器（GC—PFPD）与气相色谱-质谱（GC—MS）测试技术相结合，分析研究了催化裂化液态烃中的硫化物。采用GC—PFPD在不同来源的液态烃中检测到多种硫化物，并采用质谱选择离子扫描技术，确定这些硫化物的结构。结果表明，催化裂化液态烃中含有硫化氢、羰基硫、C1～C3硫醇、二甲基二硫醚、甲基乙基二硫醚、二乙基二硫醚、二甲基三硫醚、二甲基四硫醚等硫化物。

| Abstract: | The sulfur compounds in the liquid hydrocarbon from catalytic cracking unit were analyzed using gas chromatography pulsed flame photometric detector(GC-PFPD) and gas chromatography-mass spectroscopy(GC-MS).The sulfur compounds in the liquid hydrocarbon were detected by using GC-PFPD and were identified by using the technique of mass spectrum with selected ion monitor(SIM).The results showed that there were hydrogen sulfide,carbonyl sulfur,sulfur alcohol with methyl,ethyl and propyl group respectively,dimeth... |
