Abstract

Cumene and ethylbenzene are important compounds in the petrochemical industry for the production of phenol and styrene, respectively. Cumene and ethylbenzene are produced by benzene alkylation with propylene and ethylene. Benzene alkylation with ethylene and propylene was performed under liquid-phase reaction conditions over zeolites MCM-22, Beta, and ZSM-5. MCM-22 was a good catalyst for benzene alkylation especially with propylene, showing high activity and stability and good selectivity. The alkylation of benzene on MCM-22 occurred mainly on the external surface, in which this material is perfectly structured and formed by ~ 0.7 x 0.7 nm cups where active sites are located. Alkylation with propylene followed an Eley-Rideal type mechanism, in which benzene can also compete by the active sites but its coverage is much lower than that of propylene.
