ABSTRACT:
A process is provided for selective catalytic conversion of certain hydrocarbon feedstocks to product rich in para-dialkyl substituted benzenes. The catalyst required in the process comprises a crystalline material having the structure of PSH-3, MCM-22 or MCM-49, or a mixture of said crystalline materials, said crystalline material having been treated with one or more monomeric or polymeric siloxane compounds which decompose to oxide or non-oxide ceramic or solid-state carbon species.
