Patent ID: 7102044

Claim:
A process for alkylation of olefins comprising: a) first sending a feed stream comprising 50 to 99.99 wt-% C10 to C15 paraffins and up to 50 wt-% olefins through at least one adsorbent bed comprising one or more adsorbents selected from the group consisting of alkaline or alkaline earth cation exchange X-zeolite wherein said adsorbents remove essentially all hydrocarbon oxygenates from said stream by adsorption; b) then combining said stream with benzene to form an alkylation stream; and c) alkylating said olefins by passing the alkylation stream to a reactor containing an alkylation catalyst to convert at least a portion of said alkylation stream to alkylated benzene; wherein the process for alkylation further comprises the dehydrogenation of paraffins, removal of any aromatics contained within said feed stream in an adsorption bed and reaction of the dehydrogenated paraffin with benzene, and wherein the adsorbent bed for the removal of oxygenates comprises an adsorbent bed for removal of aromatics.
