Abstract

The invention discloses a hydrogenation catalyst and application thereof. The catalyst contains a carrier and at least one metal component selected from a group VIII and at least one metal component selected from a group VI B which are loaded on the carrier. A preparation method of the catalyst comprises the step of adopting an impregnation solution containing at least one compound selected from metal components in the group VIII and containing at least one compound selected from metal components in the group VI B for impregnating the carrier, and a preparation method of the impregnation solution comprises the following steps: (1) mixing the impregnation solution containing at least one compound selected from metal components in the group VIII and containing at least one compound selected from metal components in the group VI B with water, dissolving and reacting to obtain a solution; and (2) carrying out heating treatment on the solution obtained in the step (1), wherein the heating treatment conditions include: the temperature of 60-300 DEG C, and the time of 0.5-200 hours. Compared with the catalyst prepared by a conventional method, the catalyst provided by the invention has higher hydrogenation activity.

Description

technical field [0001] The invention relates to a hydrogenation catalyst and its application. Background technique [0002] With the increasingly stringent environmental protection requirements worldwide, countries have increasingly stringent requirements on the quality of vehicle fuel. In addition, due to the reduction of oil resources, the nature of crude oil has become heavier and worse, and refineries have to process lower-quality crude oil. Therefore, greatly reducing the content of impurities and polycyclic aromatic hydrocarbons in diesel oil and significantly improving the quality of diesel oil has become an urgent problem for oil refining companies to solve. Hydrogenation technology is one of the main technologies to reduce the impurity content of oil products and improve the quality of oil products, and its core is hydrogenation catalyst. [0003] Hydrogenation catalysts are usually prepared by impregnation, that is, impregnating a certain carrier with a solution ...
