Embodiment 1

[0028] Weigh 38g of diesel oil, add 1.0g of organic bentonite (Jiangsu Huate New Material Co., Ltd., the mass fraction of organic matter is 20-35%), and homogenize with a shearing machine. Add 1.0 g of analytically pure oleic acid, then heat and stir on an 80° C. oil bath for 1 h. The obtained homogeneous mixed oil was cooled to room temperature, 0.5 g of PEG 600, 0.2 g of sodium dodecylbenzenesulfonate, and 0.5 g of analytically pure ethylene glycol were added to homogenize at room temperature to obtain dispersion medium A.

Embodiment 2

[0030] Weigh 42 g of kerosene, add 1.0 g of organic bentonite (Jiangsu Huate New Material Co., Ltd., the mass fraction of organic matter is 20-35%), and homogenize with a shearing machine. Add 1.2g of analytically pure oleic acid, heat to 70°C and stir for 2h. After cooling to room temperature, 0.2 g of sodium oleate, 0.4 g of PEG2000, and 1.0 g of analytically pure ethanol were added. Stir evenly at high speed to obtain dispersion medium B.

Embodiment 3

[0032] Take bauxite powder whose average particle size is less than 20 μm, weigh 3.0 g and place it in a test tube. Weigh 5.0g of dispersion medium A into the same test tube, stir and vibrate with a glass rod, wait for the powder to infiltrate evenly, and let it stand for 24 hours without obvious sedimentation. Catalyst C1 is obtained.

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...
