SKI-400D型C_8芳烃异构化催化剂的工业应用

Industrial Application of SKI-400D Catalyst for C_8 Aromatics Isomerization

针对间二甲苯装置工况,开发了专用于生产间二甲苯的SKI-400D型C8芳烃异构化催化剂。该催化剂在中国石油化工股份有限公司北京燕山分公司聚酯事业部间二甲苯装置上替代SKI-500型催化剂,在主要设备不作改动的情况下,使装置产量由设计35.6 kt／a提高到40.0 kt／a,收率由83.3％提高到91.0％。

The catalyst of SKI-400D for Cs aromatics isomerization in special production meta-xylene was developed in the production plant. Catalyst of SKI-500 was replaced by the SKI-400D in the plant, Polyester Division of Beijing Yanshan Petrochemical Co., Ltd., SINOPEC, Without revamping of the main equipments, the meta-xylene production was raised from 35.6 kt/a to 40.0 kt/a, and the yield of meta-xylene was raised from 83.3% to 91.0%.
