摘要
中石化石油化工科学研究院有限公司开发了新一代加氢裂化催化剂RHC-133,该催化剂与第三代尾油型加氢裂化催化剂相比,喷气燃料选择性更高,尾油质量更优.RHC-133催化剂在中国石化齐鲁分公司的工业应用结果表明:使用该催化剂,高压加氢裂化装置的喷气燃料收率较上一周期提高3.75百分点,质量可满足3号喷气燃料的主要指标要求;柴油十六烷指数达到58.9,凝点为-47 ℃,可作为低凝柴油;尾油BMCI较上一周期降低2.0,低至9.7,是优质的蒸汽裂解制乙烯原料,装置取得了显著的经济效益和社会效益.RHC-133催化剂在中国石油某炼油厂的应用也同样取得了近似的良好效果.
Abstract
The new generation hydrocracking catalyst RHC-133 was developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.Compared with the third generation hydrocracking catalyst,the catalyst has higher selectivity of jet fuel and better quality of tail oil.The commercial application of RHC-133 catalyst in SINOPEC Qilu Company showed that the jet fuel yield of high pressure hydrocracking unit increased by 3.75 percentage points compared with the previous cycle,the diesel cetane index reached 58.9,and the pour point was-47 ℃.The tail oil BMCI decreased by 2.0 to 9.7 compared with the previous cycle.It was a high-quality feedstock for steam cracking to produce ethylene.The unit has achieved significant economic and social benefits.The application of RHC-133 catalyst in a refinery of PetroChina has also achieved similar good results.
