摘要： 制备高活性体相W-Mo-Ni体系柴油加氢精制催化剂，采用BET，XRD，SEM，TPR，TEM等分析手段对催化剂进行表征，并以催化裂化柴油为原料，对所制备的体相加氢催化剂和常规负载型催化剂进行了对比评价。分析结果表明，所制备的体相加氢催化剂活性组分具有良好的分散性和弯曲的活性相结构；评价结果表明，在体积空速为常规负载型催化剂2倍的反应条件下，体相加氢催化剂的加氢脱硫、加氢脱氮和芳烃饱和活性仍高于常规催化剂。

Abstract: A high activity bulk catalyst for gas oil hydrotreating was prepared. BET, XRD, SEM, TPR and SEM techniques were applied to characterize this new catalyst, and its hydrotreating activity was evaluated and compared with that of conventional supported catalyst using FCC LCO as feedstock. Results showed that the active components of the prepared bulk catalyst were well distributed and having curve structure. Evaluation results exhibited that as compared with the conventional catalyst at a double LHSV, this new bulk catalyst still had higher hydrodesulfurization, hydrodenitrogenation and aromatics saturation activities.
Key words: Gas oil, Hydrotreating, Bulk, Catalyst
