【摘要】 介绍了加氢裂化催化剂级配技术,该技术可以在降低冷氢量与装置能耗的同时,最大限度地提高不同产品的质量。天津石化180万吨/年加氢裂化装置催化剂级配工业应用结果表明,采用抚顺石油化工研究院新开发的高效加氢裂化催化剂级配技术,加氢精制催化剂换用FF-46,加氢裂化反应器换用FC-52/FC-32/FC-80加氢裂化催化剂级配体系,当正常生产方案时,重石脑油与航煤收率分别提高3.87%和8.47%,柴油收率降低5.81%,航煤与尾油质量均提高;采用压减柴油方案时,航煤与尾油收率分别提高1.01%和7.12%,尾油BMCI值虽有所增加,但仍能满足生产要求,达到了压减柴油目标。更多还原

【Abstract】 The hydrocracking catalysts grading technology is introduced in this paper. This technology can not only reduce the amount of cold hydrogen and unit energy consumption, but also maximize product quality. The industrial application results in the 1.80 MMt/y hydrocracking unit in Tianjin Petrochemical indicate that, when using the efficient hydrofining catalyst FF-46 and hydrocracking catalysts FC-52/FC-32/FC-80 system newly-developed by FRIPP catalyst grading technology, in normal operation mode the yields of heavy naphtha and jet fuel are increased by 3.87% and by 8.47% respectively while the yield of diesel is reduced by 5.81%, and in minimum-diesel operation mode the yields of jet fuel and bottom oil can be further increased by 1.01% and by 7.12% respectively. Although the BMCI value of bottom oil is slightly higher, it can still satisfy the operation requirement and reach the target of curbing diesel output.更多还原
