摘要
报道了由石油化工科学研究院开发的 PS-Ⅵ连续重整催化剂在中国石化镇海炼化分公司800kt/a 连续重整装置上工业应用寿命期内性能跟踪情况。结果表明,与原使用催化剂相比,PS-Ⅵ催化剂应用初期的芳烃产率提高6.46个百分点,稳定汽油收率提高1.32个百分点、氢气产率提高0.35个百分点、积炭速率降低26%以上;PS-Ⅵ催化剂具有良好的耐磨性能、活性稳定性、水热稳定性和持氯性能。与 PS-Ⅵ催化剂使用初期相比,末期 PS-Ⅵ催化剂由于杂质含量增加,加权床层入口温度(WAIT)提高4.8℃,稳定汽油收率下降1.28个百分点。
PS-VI catalyst developed by Research Institute 800 kt/a continuous catalyst regeneration reforming unit of Petroleum Processing was used in of Zhenhai Refining and Chemical Company. The commercial running results showed that PS-Ⅵ catalyst exhibited high resistant against attrition,good hydrothermal stability and chloride retention ability. As compared with the base catalyst, using PS-Ⅵ catalyst at the initial stage the yields of aromatics, reformate and hydrogen increased 6.46, 1.32 and 0. 35 percentage points, respectively; the coke rate reduced more than 26%. As compared with the catalyst at the initial stage,at the end stage（after running 1 918 days）the catalyst activity slightly decreased due to the increase of impurities, the reformate yield dropped 1. 28 percentage points.
