The preparation method of the hydrotreating catalyst comprises the following steps: (i) preparing an Al-SBA-15 molecular sieve; (ii) aluminum oxide and the Al-SBA-15 molecular sieve prepared in the step (i) are mixed, kneaded and molded, and a hydrotreating catalyst carrier is obtained through drying and roasting; and (iii) impregnating the carrier obtained in the step (ii) with an impregnating solution containing an active metal component and a polyhydroxy compound, and then drying and roasting to obtain the hydrotreating catalyst. The catalyst prepared by the method provided by the invention can deeply remove nitrogen-containing compounds in shale oil, has good hydrogenation performance, meets the quality requirements of subsequent process production, and ensures that the use performance of the cracking catalyst is fully exerted.

Description

technical field [0001] The invention relates to a hydrogenation treatment catalyst and a preparation method thereof, and the catalyst is especially suitable for the shale oil hydrogenation treatment process. Background technique [0002] Among natural resources, oil shale, like petroleum, is mainly produced by algae and other lower plankton through decay and coalification. The shale oil "squeezed" from oil shale through low-carbon distillation and other methods is called "artificial petroleum". After further processing and refining, liquid fuels such as gasoline, kerosene, and diesel can be produced. In the initial stage of oil shale mining, the development of this industry was restricted due to the unqualified technology and the pollution of the environment during the production process. In recent years, with the advancement of technology, this problem has been well solved. It is foreseeable that under the current situation of shortage of oil resources and high oil prices...
