中压加氢改质-喷气燃料加氢补充精制组合工艺生产3号喷气燃料技术的工业应用

摘要

The combined process of the medium pressure hydroupgrading(MHUG) and kerosene hydrofinishing(KHF),developed by Fushun research institute of petroleum and petrochemical,was adopted for production of No.3 jet fuel in PetroChina Karamay Petrochemical Co.Ltd.The mixture of coking diesel,FCC LCO and SR diesel was used as feedstock.Industrial application results show that after the jet fuel fraction from MHUG process was deeply hydrofinished under the mild reaction conditions,the aromatics in jet fuel product is reduced from 14.9% to 5.8%,the smoke point rises from 22 mm to 26 mm,in compliant with the quality specification of GB 6537-2006.%中国石油克拉玛依石化有限责任公司采用中国石化抚顺石油化工研究院开发的中压加氢改质-喷气燃料加氢补充精制组合工艺,以焦化柴油和催化裂化柴油为主要构成的混合柴油作原料,在缓和加氢条件下对中压加氢改质单元所生产的喷气燃料馏分进行深度加氢补充精制后,喷气燃料馏分中芳烃体积分数由14.9%降至5.8%,烟点由22 mm提高至26 mm,完全符合3号喷气燃料质量要求.
