异丁烯制备二异丁烯催化剂研究进展

Research progress on catalysts for diisobutylene production from isobutene

车用乙醇汽油政策的实施,甲基叔丁基醚今后将无法作为汽油添加剂使用。甲基叔丁基醚生产装置停产,释放大量的异丁烯资源,如何更好地利用异丁烯成为炼油企业面临的重要问题。随着环保要求的提高和油品质量的升级,烷基化油的需求将不断增长。介绍异丁烯的各种用途,综述异丁烯生产二异丁烯所用的催化剂以及在提高二异丁烯选择性方面的研究进展。

Because of the implementation of ethanol gasoline policy,methyl tert-butyl ether cannot be used as gasoline additive in the future.The shutdown of methyl tert-butyl ether plant releases a large number of isobutylene resources.How to make better use of isobutylene becomes an important issue for refineries.With the improvement of environmental protection and the upgrading of oil product,the demand for alkylated oil will be increased.Various uses of isobutylene were introduced.catalysts for diisobutylene production from isobutene and the latest research progress in selectivity improving of diisobutylene were reviewed.
