摘　　要：针对松香氢化Ni/Al2O3-MxOy催化剂的失活原因,研究了该催化剂的再生方法,得到适宜的工艺条件为:将失活催化剂在550℃焙烧3 h,再用10%硝酸镍溶液浸渍,然后于500℃下焙烧3 h,再于450℃下加氢还原2 h。经再生后的催化剂其催化性能与新鲜催化剂接近。Aiming at the causes for deactivation of Ni/Al2O3-MxOr catalyst used for hydrogenation of gum rosin, the regeneration methods of the catalyst were studied. The appropriate conditions were as follows ： the deactivated catalyst was calcined for 3 h at 550 ℃ , followed by impregnation with 10 % nickel nitrate solution, then calcined for 3 h at 500 ℃, and reduced by hydrogenation for 2 h at 450 ℃. The catalytic properties of the regenerated catalyst was close to the fresh catalyst.
