Abstract:
1. A process for alkylation of an aromatic hydrocarbon feedstream comprising: reacting a substantially linear olefin with an aromatic hydrocarbon feedstream in the presence of a catalyst under alkylation reaction conditions to produce alkylated aromatic hydrocarbon, where the catalyst comprises a layered composition consisting of an inner core, and an outer layer bonded to the inner core, wherein the outer layer comprises a zeolite selected from the group consisting of UZM-8, Faujasite, beta, MTW, MOR, LTL, MWW, EMT, BPH/UZM-4 and mixtures thereof, and a binder, and where the olefin has from 8 to 28 carbon atoms, wherein the inner core consists of a material selected from the group consisting of cordierite, alpha alumina, theta alumina, magnesia, silicon carbide, metals, zirconia, titania, and mixtures thereof, and having a substantially lower isomerization reactivity relative to the material in the outer layer and the inner core has an effective diameter from about 0.05 mm to about 5 mm, and wherein the outer layer has a thickness from 10 to 300 microns.
