HETEROGENEOUS ISOPARAFFIN/OLEFIN ALKYLATION PROCESS

摘要

A process for alkylating an isoparaffin containing up to 20 carbon atoms with an olefin containing from 2 to 12 carbon atoms comprises contacting the isoparaffin and olefin with a catalyst comprising a large pore zeolite and a Lewis acid at a temperature of -40 DEG C to 500 DEG C and a pressure up to 5000 psig (35000 kPa), wherein the molar ratio of the isoparaffin to the olefin is from 1:1 to 50:1 and the contacting takes place in the presence of water.
