ABSTRACT:
A process for the catalytic alkylation of an aromatic substrate with an alkylating agent is disclosed that comprises contacting the aromatic substrate and the alkylating agent in sequential alkylation zones to obtain an alkylaromatic. The first catalyst comprises UZM-8 zeolite and the second catalyst comprises beta zeolite. The process is particularly well suited for the alkylation of benzene with propylene to produce cumene.
