Embodiment 1

[0029] Weigh 40 g of diesel oil, add 1.2 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. Then, 1.2 g of oleic acid was added, followed by heating and stirring on an 80° C. oil bath for 2 hours. The obtained homogeneous mixed oil was cooled to room temperature, 0.5 g of PEG 600 was added, and 0.2 g of sodium dodecylbenzenesulfonate was added, and stirred at a high speed at room temperature to obtain dispersion medium A.

Embodiment 2

[0031] Weigh 36g of kerosene, 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. Then 1.2 g of oleic acid was added, heated and stirred in an oil bath at 80° C. for 2 hours. At room temperature, 0.2 g of sodium oleate and 0.4 g of PEG2000 were added. Stir evenly at high speed at room temperature to obtain dispersion medium B.

Embodiment 3

[0033] Take pyrite powder whose average particle size is less than 40 μm, weigh 5.0 g and place it in a test tube. Weigh 10.0g 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 12 hours without obvious sedimentation. Catalyst C1 is obtained.

Abstract

The invention relates to a pyrite-containing heavy oil hydrogenation catalyst, and preparation and application thereof. The heavy oil hydrogenation catalyst is composed of pyrite powder and a dispersion medium, wherein the pyrite 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 and 0.5-2 wt% of oleic acid. 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 pyrite 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 accu...
