Abstract

The invention relates to a suspension bed hydrocracking catalyst which comprises a carrier and transitional metal loaded on the carrier, and the loading capacity of the transitional metal is 0.5-10 weight percent on the metal oxide basis; the transitional metal is selected from one or a plurality of types of VIB and VIII group metals, and the carrier is catalytic cracking dead catalyst with the grain size no less than 150Mum. The suspension bed hydrocracking catalyst can be used for the suspension bed hydrogenation modification and the suspension bed hydrocracking of heavy oil and residual oil.

Description

technical field [0001] The invention relates to a suspension bed hydrocracking catalyst, in particular to a solid powder catalyst for heavy and residual oil suspension bed hydrocracking, which uses catalytic cracking waste catalyst as a carrier. Background technique [0002] Due to the increasingly heavy and inferior crude oil and the increasing demand for light fuels, the suspension bed hydrogenation technology, as one of the effective methods for upgrading residual oil, has attracted more and more attention. The technical process of the suspension bed hydrocracking is that in the presence of a catalyst and hydrogen, the heavy and residual oil mixed with the catalyst is passed through an empty cylinder or a reactor with simple internals for hydrothermal cracking reaction. The process has the characteristics of simple process flow, flexible operation, strong adaptability of raw materials, and high space velocity. Suspension-bed hydrogenation catalysts can be divided into so...
