Abstract

The invention discloses a hydrofining catalyst containing molybdenum and / or tungsten and nickel and / or cobalt, wherein the catalyst comprises a heat-proof inorganic oxide carrying agent and molybdenum and / or tungsten or tungsten and nickel and / or cobalt loaded on the carrying agent, wherein the catalyst is prepared through immersing the heat-proof inorganic oxide carrying agent with dipping solution containing molybdenum and / or tungsten and nickel and / or cobalt compound. The catalyst prepared by the process provided by the present invention has higher hydrogenation desulfurization activity than the conventional catalyst.

Description

technical field [0001] The present invention relates to a hydrorefining catalyst and its preparation method, more specifically to a hydrorefining catalyst containing molybdenum and / or tungsten and nickel and / or cobalt and its preparation method. Background technique [0002] In recent years, in order to meet the requirements of environmental protection, the harmful gas NO in automobile exhaust x , SO x Countries around the world have promulgated and implemented strict gasoline and diesel standards. This promotes the rapid development of hydrofinishing technology aimed at improving the quality of distillate oil, and hydrofining catalyst is one of the most important and key factors. [0003] Existing hydrorefining catalysts are usually catalysts loaded with Group VIB and Group VIII non-noble metal components on heat-resistant inorganic oxide carriers. It is a common preparation method for this type of catalyst to introduce the active metal componen...
