加氢裂化催化剂RHC-131的开发及其工业应用

DEVELOPMENT AND COMMERCIAL APPLICATION OF HYDROCRACKING CATALYST RHC-131

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-131。中型装置评价结果表明:与上一代尾油型催化剂相比,产物喷气燃料收率提高3.5百分点,尾油BMCI降低1.8;与国外同类型先进催化剂相比,RHC-131催化剂作用下的喷气燃料收率更高,尾油质量更优,在兼产高品质喷气燃料和优质尾油方面具有明显优势。稳定性试验结果表明,RHC-131催化剂具有很好的活性稳定性。工业应用结果表明,采用RHC-131催化剂可以提高喷气燃料收率,降低尾油BMCI,通过梯级活性级配,可大幅度降低冷氢用量,减少燃料气用量,在提高经济效益的基础上,降低能耗,减少碳排放。

A new generation hydrocracking catalyst RHC-131 was developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.The pilot results showed that compared with the previous generation hydrocracking catalyst,the yield of jet fuel increased by 3.5 percentage points,and BMCI of unconverted oil(UCO)decreased by 1.8 units.Compared with the same type of advanced catalysts abroad,catalyst RHC-131 had higher jet fuel yield and better UCO quality,and had obvious advantages in producing both high quality jet fuel and UCO.The results of stability test showed that catalyst RHC-131 had good activity stability.The results of commercial application showed that the catalyst could improve the jet fuel yield and reduce the BMCI of UCO,reduce energy consumption and CO_(2) emission on the basis of improving economic benefits.
