摘要
Abstract
The recent research progress on the mechanisms of xylene isomerization,ethylbenzene isomerization and disproportionation reaction in the process of C8 aromatics isomerization is reviewed.Combined with the reaction mechanisms,the effects of acid center,metal center and molecular sieve topological structure of C8 aromatics isomerization catalyst on the reaction performance are discussed.The modification methods and effects of isomerization catalysts are introduced from the aspects of pore structure,acidity and metal of molecular sieve.The development process of C8 aromatics isomerization technology is introduced,and the future research direction is prospected.关键词
