Abstract

The invention discloses a hydrogenation catalyst combination, as well as the preparation and the application thereof. The catalyst comprises a catalytic agent containing at least one VIII group metal component, at least two VIB group metal components and an organic addition agent, X-ray is used for diffracting the characterization, and the catalyst has diffraction peaks when d is equal to 9.8 A-12.8 A, d is equal to 3.65 A-4.65 A, d is equal to 2.1 A-3.1 A and d is equal to 1.03 A- 2.03 A. Compared with the prior art, the catalyst of the invention has higher hydrogenation activity. When the invention is used for hydro-treating hydrocarbon oil, the reaction can be carried out under milder reaction conditions. If the hydrocarbon oil hydro-treating method provided by the invention is adopted, clean diesel oil which has sulfur of lower than 10 microgram / gram and accords with the European No. V discharge standard can be directly produced under the pressure of 6.4 MPa and the temperature of 340 DEG C.

Description

technical field

[0001] The invention relates to a hydrogenation catalyst composition, a preparation method of the catalyst and a method for hydrogenation treatment of hydrocarbon oil using the catalyst. 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.

[0003] Compared with traditional supported hydrogenation...
