Abstract

A low-quality heavy oil suspension bed hydrogenation catalyst and its preparation and use method, in particular to a low-quality heavy oil suspension bed hydrogenation solid powder catalyst with sub-molten salt activated bauxite ore powder as a carrier and its preparation and use method . It is characterized in that the catalyst uses activated bauxite ore powder as a carrier, and one or several transition metals in VIB and VIII groups are loaded on it. The low-quality heavy oil hydrogenation catalyst prepared by the present invention has high catalytic activity and low coke formation rate for the hydrogenation and upgrading of low-quality heavy oil, and the source of raw materials is wide and the price is low, which can greatly reduce the preparation cost of the catalyst and hydrogenation The operating cost of the process has broad application prospects.

Description

technical field [0001] A low-quality heavy oil suspension bed hydrogenation catalyst and its preparation and use method, in particular to a low-quality heavy oil suspension bed hydrogenation solid powder catalyst with sub-molten salt activated bauxite ore powder as a carrier and its preparation and use method . Background technique [0002] In recent years, the heavy supply of crude oil has become more and more obvious, and environmental protection regulations have become increasingly stringent, which has put forward higher quality requirements for petroleum processed products, and there is an urgent need to develop inferior heavy oil (referring to conventional crude oil vacuum residue, density greater than 0.934kg / L crude oil or coal tar with similar properties) lightening and advanced processing technology. Suspension bed hydrogenation process passes highly dispersed fine particle catalysts or additives together with feedstock oil and hydrogen through the reactor. Higher...
