Problems solved by technology

[0009] Among the methods mentioned above, the preparation method of molybdenum disulfide oil is relatively simple, but if this oil is used as a hydrogenation catalyst, the effect may not be very satisfactory, because the average particle size of molybdenum disulfide obtained by this method The diameter is about 1 micron, it is difficult to reach a finer state

Embodiment 1

[0025] 25.2 g MoS 2 Add superfine powder and 205.5 grams of vacuum pump oil into the autoclave, add 1.0 grams each of Span 80 and 0P7, then add 3.0 grams of beeswax, the initial hydrogen pressure is 4.5 MPa, and then raise the temperature to 70 ° C for 3 hours, continue to heat up , react at constant temperature of 240°C and 320°C for 1 hour, then keep the hydrogen pressure at 10.0MPa, and react for 4 hours at a temperature of 380°C, keep stirring during the reaction, and the stirring rate should be kept at 300 rpm . After the reaction, the device was lowered to room temperature, the reaction product was poured into a clean bottle, and left to stand for 30 days, the unreacted precipitate was separated, and the uniform liquid product obtained was a hydrogenation catalyst containing 5.74m% molybdenum , Code C-1

Embodiment 2

[0027] 20.5 g MoS 2Add ultra-fine powder and 210.0 grams of VGO into the autoclave, add 1.0 grams of hexanol and methyl hydroxyformate, and then add 3.0 grams of heptane, the initial hydrogen pressure is 4.5 MPa, then raise the temperature to 80 ° C for 3 hours, continue Raise the temperature, react at 240°C and 320°C for 1 hour, then keep the hydrogen pressure at 10.0MPa, and react for 6 hours at a temperature of 390°C. During the reaction, keep stirring, and the stirring rate should be kept at 300 rpm point. After the reaction is finished, the device is lowered to room temperature, the reaction product is poured into a clean bottle, and left to stand for 20 days, the unreacted precipitate is separated, and the uniform liquid product obtained is a hydrogenation catalyst containing 4.80m% molybdenum , codenamed C-2

Embodiment 3

[0029] The 27.7 g WS 2 Add superfine powder and 220.2 grams of vacuum pump oil into the autoclave, add 1.0 grams each of Span 80 and OP7, then add 3.0 grams of beeswax, the initial hydrogen pressure is 4.5 MPa, and then raise the temperature to 70 ° C for 3 hours, continue to heat up , react at constant temperature of 240°C and 320°C for 1 hour, then keep the hydrogen pressure at 10.0MPa and the temperature of 385°C for 5 hours, keep stirring during the reaction, and the stirring rate should be kept at 300 rpm . After the reaction, lower the device to room temperature, pour the reaction product into a clean bottle, let it stand for 40 days, separate the unreacted precipitate, and obtain a uniform liquid product containing 6.96m% tungsten as a hydrogenation catalyst , codenamed C-3.

Abstract

The heavy oil and residual oil hydromodifying catalyst contains oily colloid of Mo and W, with the average grain size of Mo and W being below 500 nm. The catalyst may be used widely the hydrogenating reaction, hydrocracking and other technological process of heavy oil and residual oil. In the said technological processes, the catalyst containing Mo and W is first dispersed inside heavy oil and residual oil, and in the presence of hydrogen, the inferior heavy oil and residual oil is hydrogenated. The present invention aims to raise the efficiency of heavy oil and residual oil hydrogenating reaction while lowering the cost of catalyst.

Description

1. Technical field [0001] The invention relates to a heavy and residual oil hydrogenation catalyst and a preparation method thereof, in particular to a residual oil suspended bed hydrocracking catalyst. 2. Background technology [0002] my country's reserves of molybdenum and tungsten are among the top in the world. The rich mineral resources provide extremely favorable conditions and a solid foundation for my country to develop molybdenum and tungsten processing and vigorously promote the application of molybdenum and tungsten. Molybdenum and tungsten are widely used in metallurgy, aviation, aerospace, chemical industry, petrochemical, biomedicine and mechanical processing, among which only a small part is used in petrochemical field, and their applications in petrochemical field are almost all used in oil refining process hydrogenation catalyst. At present, with the increasing weight and inferior quality of crude oil, refineries are paying more and more attention to the h...
