摘要
以催化裂化过程中含硫化合物的转化规律和转化机理为基础,通过分析不同元素改性对分子筛氢转移活性和裂化活性的影响规律,研究了改性分子筛在提高裂化催化剂脱硫活性方面的作用。
Based on the mechanism of sulfide transformation in FCC process,the present paper investigates the effect of zeolite modification on desulfurization activity of FCC catalyst through analyzing the impact of different element modification on hydrogen transfer activity and cracking activity of the modified zeolite.
