FHUDS-5再生催化剂在航煤加氢装置上的应用

摘要

在中国石油兰州石化公司60万t/a航煤加氢装置上进行了柴油加氢FHUDS-5再生催化剂的工业应用,并与装置原用FHUDS-2催化剂进行了工业标定对比.结果表明:FHUDS-5再生催化剂对原料中硫、碱性氮、硫醇硫、总酸值的脱除率分别为97.81％,96.36％,94.74％,94.20％,所得精制航煤产品各项性质均达到了3#喷气燃料和军用航煤的指标要求;在达到基本相同的硫、碱性氮、硫醇硫、总酸值脱除率时,与装置原用FHUDS-2催化剂相比,FHUDS-5再生催化剂的反应温度降低了7.2℃,装置能耗下降了1.08个单位.%The diesel hydrogenation FHUDS-5 regenerated catalyst was applied in a O.6 Mt/a aviation kerosene hydrogenation unit of Lanzhou Petrochemical Company,PetroChina,and the industrial calibration was compared with the original FHUDS-2 catalyst.The results showed that with the FHUDS-5 regenerated catalyst,the removal rate of sulphur,basic nitrogen,mercaptan sulfur and the total acid number was 97.81％,96.36％,94.74％ and 94.20％ respectively,the properties of refined aviation kerosene products met the requirements of 3# jet fuel and military jet fuel.When the removal rate of sulphur,basic nitrogen,mercaptan sulfur and the total acid number were almost the same,the FHUDS-5 regenerated catalyst compared with the FHUDS-2 original catalyst,the reaction temperature of the former one decreased by 7.2 ℃,and the energy consumption of the unit decreased by 1.08 units.
