催化裂化汽油中硫化物分布的研究

Study on Sulfides Distribution in Catalytically Cracked Gasoline

精制汽油是汽油的主要来源,上海石化近期精制汽油多次出现博士试验通过,但硫醇硫超标的现象,通过运用GC-AED技术对催化裂化汽油加氢前后的硫化物进行研究,了解其中的硫化物分布,从而指导工艺生产。同时指出不同加工工艺和加工原料会造成催化汽油中的硫醇硫脱除效果不同。

Refined gasoline is the main purpose of gasoline. In Petrochemical Company Limited that the mercaptan sulfur view of the fact appearing in SINOPEC Shanghai content in refined gasoline exceeded limit though it passed the Doctor＇ s experiment, this paper studied the sulfides in catalytically cracked gasoline before and after hydrogenation with GC - AED technology, and found out the sulfides distribution in order to instruct production. It also pointed out that different process and material might cause different removing result of mercaptan sulfur from the catalytically gasoline.
