摘要
综述了近年来国内对二甲苯(PX)生产的技术进展状况,介绍了芳烃联合装置中歧化烷基化、二甲苯异构化催化剂工业应用及研发成果,以及混合芳烃分离技术工业化及研究现状,目前国内仍然以催化剂、吸附剂的研制与开发作为提高PX产量的研究重点。
Progresses in the technology for the production of p-xylene are reviewed with the focuses on the catalysts for the disproportionation alkylation and xylene isomerization as well as mixed aromatic hydrocarbon separation technologies and R＆ D status. Currently, catalysts and adsorbents are the key issues in R ＆ D in increasing the productivity of p-xylene.
