PROCESS FOR THE REMOVAL OF AROMATIC COMPOUNDS FROM THE OLEFIN FEED AND ISOBUTANE ALKYLATION PROCESS

摘要

A process for the removal of aromatic compounds from the olefin feed to a sulfuric acid paraffin alkylation by feeding a olefin containing hydrocarbon stream and a dilute alkylate stream from a paraffin alkylation to a distillation zone and removing unreacted material from said hydrocarbon stream as overheads and removing a more concentrated alkylate product stream and a portion of said aromatic compounds as bottoms and the improved alkylation process resulting therefrom.
