摘　　要：以常规金属无机盐及硫化剂为原料合成硫化物前驱体,在硫化物前驱体溶液中加入添加剂配成浸渍液,浸渍载体制成硫化型加氢催化剂。通过XPS、SEM-EDS、微反评价等分析方法对硫化型催化剂进行表征。结果表明,硫化型催化剂的硫有效利用率和硫化度均比目前广泛应用的器外预硫化催化剂高;硫化型催化剂活性组分在载体上分布均匀且硫化完全,生成了高活性的NiMoS活性相,硫化型催化剂加氢活性高。Sulfide precursors were synthesized by conventional inorganic metal salts and a sulfurizing agent. Sulfide catalysts were prepared by isochoric impregnation using an impregnation solution containing sulfide precursors and a dispersion additive. The prepared catalysts were characterized by means of XPS,SEM-EDS,micro-activity test et al,and a commercial ex-situ presulfided catalyst was used as reference catalyst. Test results showed that as compared with the ex-situ presulfided catalyst, the effective utilization rate of sulfur and the sulfiding degree of the prepared catalysts were higher; the active components dispersed on the support uniformly and formed high active NiMoS phase, thus the prepared catalysts exhibited high hydrofining activity.
