ISOBUTYLENE-ISOBUTANE ALKYLATION PROCESS IN LIQUID HF REVISITED

摘要

The isobutylene-isobutane alkylation process is a very important industrial process,being responsible for the production of high octane number gasoline,which has as the main component isooctane.Liquid HF or H_4SO_4 can be used as catalysts for this reaction.But,because of the highly corrosive nature of these media,associated ecological problems,and intrinsic danger in handling these materials,alternative solutions to replace these catalysts are being actively searched for in the petroleum industry.However,many problems arise in finding good heterogeneous catalysts for this reaction.Usually,they are rapidly deactivated yielding oligomeric olefins instead of the desired branched alkane as the product.
