本文介绍了中石化上海石油化工研究院研制的SEB-08新型高效稀乙烯制乙苯催化剂在中石化安庆分公司10.6万吨/年乙苯装置的使用情况,与装置原使用催化剂相比,该催化剂具有处理量大、乙烯转化率高、乙基选择性好、活性和抗波动能力强、稳定性好、装填量少且装填方便、投用前不需要活化、再生次数少等优点,使用过程中表现出优异的性能,乙烯转化率始终保持在96%以上,乙苯产品的纯度不低于99.80%,产品中杂质二甲苯的含量不大于600 ppm,为现有干气制乙苯装置提高产品乙苯品质,降低物耗和能耗,提高经济效益,增加竞争力提供了强有力的技术保障。
This article describes the Sinopec Shanghai Petrochemical Research Institute developed SEB-08 new highly efficient dilute ethylene ethylbenzene catalyst in Anqing Branch of Sinopec 106,000 tons / year ethylbenzene plant usage, compared with the original device used in the catalyst, the catalyst has Large amount of handling, ethylene conversion rate, ethyl selectivity, activity and anti-volatility, good stability, less loading and filling convenience, do not need to be activated before use, the fewer regeneration times, the performance of the use of the process Excellent performance, ethylene conversion rate is always maintained at above 96%, ethylbenzene product purity of not less than 99.80%, the product content of xylene impurities not more than 600 ppm, for the existing dry gas ethyl benzene plant to improve product B Benzene quality, reduce material and energy consumption, improve economic efficiency, increase competitiveness provides a strong technical support.
