摘要
为满足市场对喷气燃料和优质尾油的需求,中国石化石油化工科学研究院开发了新一代加氢精制催化剂RN-410和加氢裂化催化剂RHC-131,通过考察原料油、转化深度、产品切割方案对喷气燃料及尾油的影响规律并结合催化剂的级配优化方案,开发了大比例增产喷气燃料、改善尾油质量的加氢裂化技术,并在中国石化北京燕山分公司成功应用。工业应用结果表明,在石脑油收率约为22%的情况下,喷气燃料馏分油收率达43%以上,产品质量满足3号喷气燃料要求,将柴油并入尾油中,尾油BMCI值为8.7,是优质的蒸汽裂解制乙烯原料。
New generations of hydrotreating catalyst RN-410 and hydrocracking catalyst RHC-131 were developed by SINOPEC Research Institute of Petroleum Processing to meet the market demand for jet fuel and high quality unconverted oil.The influence of feedstocks,conversion level and production fractionation methods on jet fuel and unconverted oil were studied with the optimized catalysts grading.A hydrocracking process for greatly increasing jet fuel yield and improving unconverted oil quality was developed and applied successfully in a 2.0 Mt a hydrocracking unit of SINOPEC Beijing Yanshan Company.The application indicated that the yield of jet fuel is above 43%when the naphtha yield is 22%,and the qualities meet the requirements of No.3 jet fuel.The BMCI value of the unconverted oil mixed with the diesel fraction is 8.7,a high quality feedstock for steam cracking.
