ABSTRACT:
A process is presented for the production of linear alkylbenzenes. The process includes contacting an aromatic compound with an olefin in the presence of a selective zeolite catalyst. The catalyst includes two zeolites combined to improve the linearity, and to produce detergent grade LAB. The two zeolites are selected to limit skeletal isomerization while producing a desired 2-phenyl content for the LAB.
