Abstract

The invention discloses an oil-soluble catalyst and a preparation method thereof. The oil-soluble catalyst comprises metal Mo and / or W in VIB group, and at least one of metal Fe, Co or Ni in VIII group. The total content of metals in VIB group and VIII group is 10-30wt%, and the mol ratio of the metal in VIB group and VIII group is 1:10-10:1. In the preparation process, organic solvents are not needed, the oil-soluble catalyst which contains high content of active metals is prepared at a lower reaction temperature. The catalyst has high hydrogenation activity and excellent catalysis performance, the catalyst is applied to a slurry bed hydrocracking process of inferior heavy oil, coke yield is substantially reduced, and conversion rate of inferior heavy oil and yield of light oil are improved.

Description

technical field

[0001] The invention belongs to the technical field of hydrocracking catalysts in coal chemical industry and petrochemical industry, in particular to an oil-soluble catalyst and a preparation method thereof, in particular to an oil-soluble slurry bed hydrocracking catalyst and a preparation method thereof. Background technique

[0002] The slurry bed hydrogenation process is a hydrogenation process based on the hydrocracking reaction of heavy / inferior feedstock oil in the presence of hydrogen and catalysts. It is mainly used in the processing of heavy crude oil, heavy oil / residual oil, and high, medium, and low temperature Coal tar lightening, kerosene co-refining and other fields. Compared with the fixed bed hydrogenation process, the slurry bed hydrogenation process is more adaptable to raw materials and can process various low-quality raw materials. Therefore, it has become a new type of heavy oil upgrading process, especially with the increase of heavy oi...
