国内外甲苯歧化工艺研究,一直围绕着对传统的4种歧化工艺技术改进。一方面以提高产物中对二甲苯的热力学平衡浓度为目的,通过改变甲苯歧化催化剂的性能,以纯甲苯为原料,可获得较高的转化率和对二甲苯的选择性。另一方面,不断探索混合甲苯的歧化工艺,充分利用三甲苯原料;并综述了国内外甲苯歧化催化剂的现状及研究进展。

Toluene disproportionation technologies developed at home and abroad overyears all compared with and studied,and disproportionation technologies of pure toluene and disproportionation technologiesthe mixture of C9 and toluene were discussed.It was possible to selectively disproportion the mixture to P-xylene with the present industrialized catalyst,and the status and research developments of the catalysts for toluene disproportionation were reviewed.
