A kind of heavy oil hydrogenation catalyst containing bauxite ore and its preparation and application

Abstract

The invention relates to a bauxite-containing heavy oil hydrogenation catalyst, and preparation and application thereof. The heavy oil hydrogenation catalyst is composed of bauxite powder and a dispersion medium, wherein the bauxite powder accounts for 5-70 wt% of the catalyst; and on the basis of the dispersion medium, the dispersion medium contains 80-99% of base oil, 0.05-10 wt% of surfactant, 0.05-10 wt% of solid thickening rheological agent, 0.5-2 wt% of oleic acid and 0.05-10 wt% of polar additive. The heavy oil hydrogenation catalyst provided by the invention has the advantages of high catalytic-activity solid content, favorable mixing capacity with heavy oil raw oil, and favorable catalytic effect in heavy oil hydrocracking or modification in a suspension bed or slurry-state bed.

Description

technical field [0001] The invention relates to a heavy oil hydrogenation catalyst. More specifically, it is a catalyst containing bauxite ore powder for hydrogenation of heavy oil, and the preparation method and application of the catalyst. Background technique [0002] With the gradual scarcity of conventional oil resources, the proportion of heavy oil, especially low-quality heavy oil, in the total oil is increasing. How to efficiently convert heavy oil has become a huge challenge in the energy field. The heavy oil referred to above includes asphalt, oil sands, shale oil, residual oil with a boiling point higher than 524°C, etc. Its characteristics are: high asphaltene and residual carbon content, high metal nickel and vanadium content, the total content is generally not less than 200μg / g, high S and N compound content, and high apparent viscosity at normal temperature and pressure. Inferior heavy oil is prone to clogging pipelines and reactors and producing coke due to...
