摘要
介绍了中石化石油化工科学研究院有限公司研制开发的乙苯转化型C8芳烃异构化催化剂RIC-300的工业试验.结合在某芳烃装置的首次工业应用试验,分析了 RIC-300催化剂处理乙苯含量高的原料的性能.应用结果表明:RIC-300催化剂在温和工况下异构化活性(产物中对二甲苯含量与二甲苯含量的比值)达到23.4％以上,乙苯转化率达到39.8％,C8芳烃损失率为1.9％.在高负荷、高转化率的苛刻操作条件下,催化剂的提温和提压速率低,表明RIC-300催化剂具有高活性、高选择性、稳定性好的特点.
Abstract
The commercial test of ethylbenzene conversion type C8 aromatics isomerization catalyst RIC-300 developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.was introduced.The performance of catalyst RIC-300 for the feedstock with high content of ethylbenzene was analyzed based on its first commercial application test in an aromatics plant.The results showed that the activity of catalyst RIC-300 was over 23.4％(p-xylene/xylene),the conversion rate of ethylbenzene was over 39.8％,and the loss rate of C8 aromatics was 1.9％under mild conditions.Under the harsh operating conditions of high load and high conversion,the rate of raising temperature and pressure was low.The catalyst RIC-300 had the characteristics of high activity,high selectivity and good stability.
