Process for the alkylation of benzene-rich gasoline

摘要

A process is disclosed for enhancing the alkylation conversion rate of a benzene-rich gasoline boiling range hydrocarbon feedstream alkylated with C2-C5 olefins. The process comprises contacting the benzene-rich stream and olefins sequentially in decreasing order of olefin oligomerization activity comprising a first contact with C3-C5 olefins followed by contact with C2 olefin, preferably at different points of an alkylation zone containing solid, shape selective aluminosilicate catalyst particles under benzene alkylation conditions. Gasoline is produced having a reduced benzene content.
