采用共沉淀法制备镍基催化剂的前躯物，该前躯物经捏合成型焙烧后制成石油树脂加氢催化剂。对沉淀工艺条件、助剂及不同镍盐进行考察。结果表明，通过调整沉淀工艺条件参数，可以制备出适合石油树脂加氢所需的大孔催化剂；选择合适的镍盐和助剂，能够制备出镍晶粒较小的镍基催化剂，同时助剂的加入抑制了 Ni 晶粒的增长并提高催化剂容硫能力。制备的镍基石油树脂催化剂具有很强的烯烃饱和性能，且加氢后石油树脂的软化点下降幅度很小。加氢前后的石油树脂结构变化很小，说明所制备的催化剂具有很强的烯烃饱和性能，且加氢后石油树脂的软化点下降幅度很小。

The precursors of Ni-based petroleum resin hydrogenation catalyst were prepared by coprecipitation and were made into hydrogenation catalyst through a series of process.The coprecipitation conditions,promoters and different nickel salts were studied in detail.The results showed that the large pore catalysts of petroleum resin hydrogenation was prepared by adjusting coprecipitation process parameters.The Ni-based catalysts of small Ni grain was prepared by selecting the suitable nickel salt and promoter,and the promoter can inhibit Ni grain to grow up and improve the catalyst capacity of holding sulfur. The Ni-based petroleum resin hydrogenation catalyst was provided with very strong olefin saturation properties,and its softening point of hydrogenated petroleum resin had a less decrease.
