Abstract: The Ni-based hydrogenation catalysts (Ni/SiO₂, Ni/Al₂O₃ and Ni/Al₂O₃-SiO₂) with SiO₂, Al₂O₃ and Al₂O₃-SiO₂ composite material as carriers were prepared. In addition, hydrogenated decolorization activity of petroleum resin was evaluated on the micro hydrogenation reactor using above catalysts. The results show that the catalysts of Ni/SiO₂，Ni/Al₂O₃and Ni/Al₂O₃-SiO₂ can achieve the effect of decolorization petroleum resin. The softening point of hydrogenation petroleum resin with Ni/SiO₂ catalysts is the smallest and declined about 4 ℃, while the larger decline is Ni/Al₂O₃-SiO₂

摘要： 　分别以ＳｉＯ_２，Ａｌ_２Ｏ_３和Ａｌ_２Ｏ_３－ＳｉＯ_２复合材料为载体制备了Ｎｉ基石油树脂加氢催化剂（Ｎｉ／ＳｉＯ_２，Ｎｉ／Ａｌ_２Ｏ_３和Ｎｉ／Ａｌ_２Ｏ_３－ＳｉＯ_２），并在微型加氢反应装置上对石油树脂进行加氢脱色活性评价。评价结果表明，Ｎｉ／ＳｉＯ_２，Ｎｉ／Ａｌ_２Ｏ_３和Ｎｉ／Ａｌ_２Ｏ_３－ＳｉＯ_２催化剂均能达到石油树脂脱色的效果，以Ｎｉ／ＳｉＯ_２为石油树脂加氢催化剂的产品软化点下降幅度最小，下降４℃，以Ｎｉ／Ａｌ_２Ｏ_３－ＳｉＯ_２为石油树脂加氢催化剂得到的加氢石油树脂软化点下降幅度较大。
