RIC-200转化型二甲苯异构化催化剂的工业应用

Industrial Application of RIC-200 Catalyst in Xylene Isomerization

介绍了中国石化天津分公司1#芳烃联合装置采用中国石化石油化工科学研究院开发的新型RIC-200转化型二甲苯异构化催化剂的工业应用情况。工业应用结果表明,RIC-200催化剂具有采用还原态、开工过程不需要注硫钝化、装置首次开工时间短、操作风险低等特点;将装置原来采用的SKI-400催化剂换装为RIC-200催化剂后,对二甲苯增产显著,副产物明显减少。与国内外同类催化剂相比,RIC-200催化剂的性能明显优于SKI-400催化剂,达到国外同类OPARIS PLUS催化剂的先进水平。

The application of the new RIC-200 xylene isomerization catalyst in SINOPEC Tianjin Petrochemical Corporation Branch was introduced.The industrial application results indicated that RIC-200 catalyst had several outstanding characteristics： high activity,high selectivity,non-sulfur passivation,non-injecting water,short start-up time and low operating risk.The p-xylene product increased evidently after RIC-200 catalyst was used.Compared with the domestic and overseas catalysts,the performance of RIC-200 catalyst exceeded SKI-400 distinctly and achieved the advanced level of OPARIS PLUS catalyst.
