摘要：
The present invention pertains to a process for preparing a catalyst composition wherein at least one Group VIII non-noble metal component and at least two Group VIB metal components are combined and reached in the presence of a protic liquid, after which the resulting composition is isolated and dried, the total of the Group VIII and Group VIB metal components, calculated as oxides, making up at least 50 wt.% of the catalyst composition, calculated on dry weight characterised in that an organic oxygen-containing additive is added prior to, during, or subsequent to the combining and reacting of the metal components in such and amount that the molar ratio of the total amount of Group VIII and Group VIB metal components is at least 0.01. The invention also pertains to additive-containing catalysts obtained by this process, and to their use in hydroprocessing.
摘要（中）：
本发明涉及一种制备催化剂组合物的方法，其中在质子液体存在下将至少一种第VIII族非贵金属组分和至少两种VIB族金属组分合并并达到，然后将所得组合物分离 并干燥后，按干重计算，按氧化物计算的第VIII族和第ⅥB族金属组分的总量占催化剂组合物的至少50重量％，其特征在于在有机含氧添加剂之前加入， 在金属组分的组合和反应期间或之后，并且其量使得第VIII族和第ⅥB族金属组分的总量的摩尔比至少为0.01。 本发明还涉及通过该方法获得的含添加剂催化剂及其在加氢处理中的用途。
