摘　　要：对中国石化北京化工研究院现有的裂解C^(+)_(9)加氢精制催化剂的制备技术进行开发和改进。采用N_(2)吸附-脱附,SEM等方法对新研发的催化剂进行表征,并进行实验室长周期小试评价、C^(+)_(9)馏分应用评价和工业应用评价研究。表征结果显示,新生产的Al_(2)O_(3)-TiO_(2)复合氧化物载体在孔结构与催化剂表面形貌分布上与之前的高性能载体相接近。实验结果表明,新开发的载体生产路线比过去的载体路线生产成本降低50%以上,废水排放量降低70%;新型BY-7型裂解汽油二段加氢催化剂在长周期评价中表现出了更高的加氢饱和活性和加氢脱硫活性、且稳定性好;使用工业C^(+)_(9)原料评价工业生产的催化剂性能达标;BY-7型催化剂在工业装置应用时,加氢效果好,运行第一周期内所有技术指标达到要求。The preparation technology of pyrolysis C^(+)_(9) hydrofining catalyst in Sinopec Beijing Research Institute of Chemical Industry was developed and improved.N2 adsorption-desorption,SEM and other methods were used to characterize the newly developed catalyst.Besides,the longterm laboratory test,application evaluation of C^(+)_(9) fraction and industrial application were carried out.Results show that the newly developed Al_(2)O_(3)-TiO_(2) composite oxide carrier was similar to the previous high-performance carrier in the pore structure and surface morphology.The production cost of the newly developed carrier production route was over 50%lower than that of the previous carrier route,and the discharge water was reduced by 70%.The new BY-7 pyrolysis C^(+)_(9) hydrogenation catalyst which adopted Al_(2)O_(3)-TiO_(2) composite carrier exhibited higher hydrogenation saturation activity and hydrodesulphurization activity and better stability in the long period evaluation.The performance of the industrial catalysts evaluated by industrial C^(+)_(9) raw material reached the standard.The new BY-7 catalyst had been applied in the industrial plant,showing good hydrogenation effect,and all of its technical indexes met the requirements in the operation cycle.
