二甲苯异构化催化剂研究进展

Research Progress of Xylene Isomerization Catalyst

本文综述了近年来乙苯转化型和脱乙基型二甲苯异构化催化剂的研究进展。重点介绍了乙苯转化型和乙苯脱乙基型两种技术路线的技术特点,分别介绍了两种催化剂的研究以及工业应用情况,展望了未来催化剂技术的发展。

This article reviewed the recent research progress of two types xylene isomerization catalysts, i.e., Ethylbenzene refonning catalyst and Ethylbenzene de-alkylation catalyst. Introduced the difference between Ethylbenzene reforming process and Ethylbenzene de-alkylation process. Summarized the research and commercialization progress of two kinds of catalysts. Outlooked the possible way for catalyst further development in future.
