CATALYST FOR THE ALKYLATION OF AROMATIC HYDROCARBONS

摘要

The present invention relates to catalyst composition prepared by a method wherein an aluminosilicate zeolite having its pores filled with templating agent with a specific organic silicon compound to deposit said organic silicon compound on the surface of the zeolite to provide an organosilicon treated catalyst precursor; and calcining the organosilicon treated catalyst precursor under conditions sufficient to remove the templating agent from the zeolite. Furthermore, the present invention relates to a method for preparing said catalyst composition and a process for alkylation of an aromatic hydrocarbon comprising contacting the catalyst composition of the present invention with a feed stream comprising said aromatic hydrocarbon and an alkylating agent under aromatic alkylation conditions.
