摘　　要：首次利用相对质量响应因子建立了GC-FID/MS技术分析裂化液体中硫化物的方法,并将其应用于苯并噻吩催化裂化转化规律的研究。结果表明,该方法的准确度较高,苯并噻吩催化裂化反应后的硫平衡均高达95%以上。在催化裂化条件下,纯苯并噻吩很难开环裂化脱硫,四氢萘的加入可明显促进苯并噻吩的转化,提高气体硫的摩尔选择性,并降低裂化汽油馏分段的硫含量。By using relative quality response factor, a method was established to analyze sulfur- containing compounds in liquid product by GC-FID/MS technology, and was applied to the investigation of benzothiophene transformation under FCC condition. The results showed that the method had high accuracy, and sulfur equilibrium exceeded 95% in benzothiophene cracking systems. Under FCC condition, it was very difficult for pure benzothiophene to be cracked into H2S. However, the conversion of benzothiophene and the selectivity of H2S were enhanced to a great extent system, and Key words： after the addition of tetralin in reaction system, compared with pure benzothiophene the sulfur content distributing in gasoline fraction decreased.
