以六水硝酸镍和钠水玻璃为镍源和硅源、碳酸钠为沉淀剂、聚乙烯吡咯烷酮为分散剂，采用共沉淀法合成了C₉石油树脂加氢催化剂；对催化剂制备的搅拌方式、共沉淀温度、老化时间和剪切速率进行了研究，考察了反应条件对C₉石油树脂加氢的影响。结果表明，与普通搅拌相比，在高速剪切下所制备的催化剂活性组分分散性更好，在共沉淀温度为70℃、老化时间为0 h、剪切速率为900 r/min下所制备的催化剂在高负载的同时比表面积达到472 m²/g，具有微-介-大孔的多级孔道结构，形貌为纳米片组成的蜂窝状不规则球体。在反应温度为270℃、H₂压力为6 MPa、反应时间为2 h及C₉石油树脂与溶剂质量比为1∶2时，C₉石油树脂的氢化率达到96.59%，循环套用7次后氢化率仍然在95%以上。

The catalysts for C₉ petroleum resin hydrogenation are synthesized via the co-precipitation method with nickel nitrate hexahydrate as nickel source, sodium silicate as silicon source, sodium carbonate as precipitant and polyvinylpyrrolidone as dispersant.The stir pattern, co-precipitation temperature, aging time and shear rate in the preparation of catalyst are investigated, as well as the effect of reaction conditions on the hydrogenation of C₉ petroleum resin are evaluated.It is found that the active components of the catalysts prepared under high speed shear have better dispersibility than those prepared under ordinary agitation.The catalyst prepared at a precipitation temperature of 70℃, an aging time of 0 h and a shear rate of 900 r·min^-1 shows a high load, a specific surface area of 472 m²·g^-1, a microporous-mesoporous-macroporous multi-stage channel structure, and a honeycombed irregular sphere morphology that is composed of nanosheets.The hydrogenation rate of C₉ petroleum resin reaches 96.59% when the reaction temperature is 270℃, the pressure of H₂ is 6 MPa, the reaction lasts for 2 h and the mass ratio of C₉ petroleum resin to solvent is 1:2.The hydrogenation rate remains still above 95% after the catalyst has been used for 7 cycles.
