Abstract

The invention discloses a heavy oil hydrotreatment catalyst carrier, a catalyst and a preparation method thereof. The preparation method of the carrier comprises the following steps: mixing pseudo-boehmite powder and an ammonium phosphate aqueous solution, and molding to obtain a carrier precursor; and treating the carrier precursor by using steam-containing gas, further drying and roasting to obtain a catalyst carrier, and further loading a hydrogenation active metal component on the obtained catalyst carrier to obtain the catalyst. According to the method, the strength and the wear resistance of the carrier can be improved, so that the activity and the stability of the catalyst are integrally improved.

Description

technical field [0001] The invention belongs to the technical field of oil refining and chemical industry, and relates to a catalytic material and a preparation method thereof, in particular to a hydrogenation catalyst carrier, a catalyst and a preparation method thereof. Background technique [0002] In recent years, the quality of crude oil has deteriorated day by day, but the demand for light oil products has increased year by year. Therefore, it is of great practical significance to develop deep processing of heavy oil and increase the added value of products. As the main processing method, hydrogenation technology is facing great challenges, and it is urgent to develop better hydrogenation processes and hydrogenation catalysts with higher activity. The reactivity of heavy oil hydrogenation catalysts depends not only on the intrinsic catalytic properties of the active components, but also on the properties of the catalyst support. The specific surface area, pore structu...
