RIC-270型C8芳烃异构化催化剂的工业应用性能特点

PERFORMANCE OF C8 AROMATICS ISOMERIZATION CATALYST RIC-270 IN INDUSTRIAL APPLICATION

介绍了中国石化石油化工科学研究院研制开发的RIC-270乙苯转化型C8芳烃异构化催化剂的特点。结合在中国石化扬子石油化工有限公司2号对二甲苯装置的工业应用情况,分析了RIC-270催化剂对该对二甲苯装置高乙苯原料的适应性。应用结果表明:RIC-270型催化剂异构化活性(对二甲苯二甲苯质量比)达到23.3%以上,乙苯转化率达到36.5%,C8芳环损失率为1.7%。RIC-270型催化剂在高负荷、高转化率的苛刻操作条件下,平均C8芳烃损失率为2.5%,提温和提压速率低,具有高活性和选择性、良好的稳定性,产生的经济效益显著。

The C8 aromatics isomerization catalyst RIC-270 for ethylbenzene conversion,developed by SINOPEC Research Institute of Petroleum Processing,was applied in SINOPEC Yangzi Petrochemical Company ’s No.2 para-xylene plant.The adaptability of RIC-270 catalyst to high ethylbenzene content feedstock was investigated.The application results showed that the isomerization activity of RIC-270 catalyst reached more than 23.3%,ethylbenzene conversion rate reached 36.5%,and C 8 ring loss was 1.7%.The average C 8 aromatics loss was as low as 2.5% under the harsh operating conditions of high load and high conversion rate,the temperature and pressure rising rate was low.The catalyst has high activity and selectivity,good stability,and remarkable economic benefits.
