Embodiment 1

[0025] Weigh 40 g of diesel oil, add 0.9 g of organic bentonite (Jiangsu Huate New Material Co., Ltd., the mass fraction of organic matter is 15-20%), and homogenize with a shearing machine. Then heat and stir on an oil bath at 60°C for 2 hours, add 0.5 g of analytically pure ethylene glycol, stir until homogeneous, and then cool to room temperature to obtain dispersion medium A.

Embodiment 2

[0027] Weigh 38 g of kerosene, add 0.8 g of fumed silica (particle size less than 1 μm), and homogenize with a shearing machine. Then heated and stirred on an oil bath at 50° C. for 2 h, added 0.2 g of glycerol, stirred until homogeneous, and then cooled to room temperature to obtain dispersion medium B.

Embodiment 3

[0029] Take limonite powder whose average particle size is less than 20 μm, weigh 6.0 g and place it in a test tube. Weigh 12.0g of dispersion medium A into the same test tube, stir and vibrate with a glass rod, after the powder is evenly infiltrated, let it stand for 6 hours without obvious sedimentation. Catalyst C1 is obtained.

Abstract

The invention relates to an iron-oxide-ore-containing heavy oil hydrogenation catalyst, and preparation and application thereof. The heavy oil hydrogenation catalyst is composed of iron oxide ore powder and a dispersion medium, wherein the iron oxide ore powder accounts for 5-70 wt% of the catalyst; and on the basis of the dispersion medium, the dispersion medium contains 80-99 wt% of base oil, 0.05-10 wt% of solid thickening rheological agent 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 for heavy oil hydrogenation containing iron oxide ore powder, as well as 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...
