摘　　要：介绍了自主开发的THFS-2加氢精制催化剂在陕西延长石油(集团)有限责任公司榆林炼油厂20万吨/年DCC催化裂解石脑油加氢装置的工业应用情况。通过BET、XRD和H_(2)-TPR等方法对THFS-2加氢催化剂的理化结构进行表征,揭示了其高加氢活性的原因。中试实验和工业生产装置运行数据表明,THFS-2加氢精制催化剂在处理高硫高氮、高烯烃高二烯烃和高芳烃的劣质催化裂解(DCC)汽油时表现出优异的活性和稳定性,可以生产出硫、氮质量分数均小于1.0μg·g^(-1)、溴价小于0.5 gBr·(100g)^(-1)的产品,各项指标均优于芳烃抽提进料的要求。与上一周期参比剂相比,反应器平均温度降低,反应温升平稳可控,装置可长周期稳定运转。The commercial application of self-developed THFS-2 catalyst in a 200,000 TPY deep catalytic cracking(DCC)unit in Yulin Refinery of Yanchang Oil Group is introduced.The physicochemical structure of THFS-2 hydrogenation catalyst was characterized by BET,XRD and H_(2)-TPR,and the reason of its high hydrogenation activity was revealed.The pilot experiment and the industrial application show that the THFS-2 hydrofining catalyst has excellent activity and stability in the treatment of deep catalytic cracking(DCC)gasoline with high sulfur,high nitrogen,high olefin,high diolefin and high aromatics.The product with mass fraction of sulfur and nitrogen less than 1.0μg·g^(-1) and value of bromine less than 0.5 gBr·(100g)^(-1) can be produced.All the indexes are better than the requirements of aromatics extraction feed.Compared with the previous cycle reference agent,the average temperature of the reactor is reduced,the reaction temperature rise is stable and controllable,and the device can run stably for a long period.
