Patent ID: 7973206

Claim:
An alkylation process for the selective alkylation of an aromatic compound, comprising contacting the aromatic compound with an olefin having from 8 to 16 carbon atoms in the presence of a selective zeolite catalyst at reaction conditions, wherein the selective zeolite catalyst comprises a zeolite mixture, the zeolite mixture comprising a first zeolite having a UZM-8 content between 10 and 90% by weight, a second zeolite comprising a rare earth substituted X zeolite, and comprising an amount between 10 and 90% by weight, wherein the reaction conditions include a temperature between 80° C. and 200° C. and a pressure between 1300 kPa and 7000 kPa, and the X zeolite has a silica to alumina ratio of less than 2.8; and a rare earth element incorporated into the second zeolitic framework in an amount greater than 16.5 wt %.
