本文研究通过对氢转移反应与催化裂化进行概述,着重分析了催化裂化氢转移反应活性受到稀土含量、硅铝比、晶粒度、催化剂孔结构以及基质与沸石的相互作用等方面的影响,并说明依靠对催化剂相关技术的完善、选用适当的操作技术以及良好活性的氢转移催化剂,不但能够对催化裂化汽油烯烃含量加以降低控制,而且在保证辛烷值不降低的同时,有效抑制焦炭的形成,从而提供给相关部门及人员更多的指导和帮助。
In this paper, the hydrogen transfer reaction and catalytic cracking are summarized, and the effects of rare earth content, Si / Al ratio, grain size, pore structure of catalyst and interaction between matrix and zeolite are mainly analyzed. Rely on the catalyst-related technology to improve, select the appropriate operating techniques and good activity of the hydrogen transfer catalyst, FCC gasoline can not only reduce the olefin content control, and to ensure that the octane does not decrease at the same time, effectively inhibit the formation of coke , Thus providing the relevant departments and personnel more guidance and help.
