中压加氢裂化生产合格喷气燃料技术开发与应用

为满足市场对喷气燃料的需求并与企业现有装置相契合,中国石化石油化工科学研究院（简称石科院）开发了生产合格喷气燃料的中压加氢裂化技术。通过考察反应压力、裂化催化剂、原料油、转化深度及体积空速对喷气燃料性质的影响规律,提出了中压条件生产合格喷气燃料的加氢裂化技术方案。中压加氢裂化生产合格喷气燃料技术在中国石化上海石油化工股份有限公司1.5 Mt/a中压加氢裂化装置得到工业应用,在国内首次实现了中压条件下蜡油生产合格喷气燃料。装置工业标定结果表明,采用该技术加工高硫减压蜡油（VGO）馏分,在氢分压约10 MPa的条件下,喷气燃料馏分收率达到20%以上,且满足3号喷气燃料质量要求,尾油馏分BMCI值约为10,是优质的裂解制乙烯原料。

DEVELOPMENT AND APPLICATION OF MEDIUM PRESSURE HYDROCRACKING TECHNOLOGY FOR PRODUCING QUALIFIED JET FUEL

In order to meet the market demand for jet fuel with the existing equipment of enterprises, developed a technology of medium-pressure hydrocracking to produce qualified jet fuel. The effects of reaction pressure, cracking catalyst, feedstock oil, conversion depth and LHSV on the properties of jet fuel product were investigated. The technology was applied in a medium pressure hydrocracker with capacity of 1.5 Mt/a in SINOPEC Shanghai Petrochemical Co. Ltd., and was certificated by the aviation certification committee in Nov. 2018. It was the first time to produce qualified jet fuel from vacuum gas oil under medium pressure in China. The commercial results showed that by the technology, the yield of jet fuel from feed VGO reached more than 20%, and the product met the quality requirements of No. 3 jet fuel, and the tail oil had BMCI of 10, a kind of excellent raw material for cracking to ethylene.
