PROCESS FOR MAKING CUMENE BY ALKYLATION OF BENZENE USING AN ORGANOTEMPLATE-FREE ZEOLITE BETA

摘要

A process for making cumene by the alkylation of benzene with propylene using a benzene alkylation catalyst that comprises an organotemplate-free zeolite beta having a silica-to-alumina molar ratio of less than 20 and synthesized without an organic structure directing agent (SDA).

主权项

1. A process for preparing cumene by alkylation of benzene with propylene, wherein said process comprises:
contacting a feed mixture, comprising benzene and propylene, at a reduced reactor inlet temperature and an elevated WHSV, with a benzene alkylation catalyst contained within a reaction zone defined by a reactor, wherein said benzene alkylation catalyst comprises an organotemplate-free zeolite beta, having a silica-to-alumina molar ratio (SAR) of less than 20, that is synthesized in the presence of a material absence of an organotemplate; and yielding an alkylation product, comprising cumene.
