Abstract:
1. 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 and aromatics from said stream by adsorption in the liquid phase; 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.
