摘要
中国石化安庆分公司2.0 Mt/a渣油加氢装置采用中国石化石油化工科学研究院(石科院)开发的RHT技术,具有第一反应器(R-101)可切出的工艺特点。第一周期和第二周期均采用石科院开发的第三代RHT系列渣油加氢催化剂以及相应的催化剂级配技术。两个周期的工业应用结果表明:R-101切出工艺技术可行,催化剂级配技术合理。R-101切出后,对产品质量没有影响,产品质量完全满足下游催化裂化原料的要求;同时能够延长装置运行周期2~3个月,最大限度地发挥催化剂的活性。
The RHT technology licensed by SINOPEC Research Institute of Petroleum Processing(RIPP)was applied in 2.0 Mt a residue hydrotreating unit at Anqing Company,SINOPEC.The process is characterized by the cutting-out of the first reactor R-101.The 3 rd generation RHT serious catalysts and the optimized catalyst grading technology developed by RIPP were adopted in first and second cycles(RUN-1 and RUN-2).Commercial applications in both runs showed that R-101 cutting out technology is feasible and the catalyst grading technology is reasonable.After R-101 is cut-out,the product quality is almost not affected and meets the requirements for RFCC feedstock;the cycle length can be prolonged for two or three months and the activity of catalyst system can be fully utilized.
