Problems solved by technology

[0004] The above-mentioned patent uses carbon nanotubes as the carrier to prepare the catalyst. Due to the low force between the carrier and the active metal, the active components are easy to aggregate and grow up during the catalytic process, gradually reducing the active center and reducing the catalyst activity; and the carbon nanotubes As a carrier of hydrogenation catalyst, the cost is relatively high and it is difficult to be industrialized on a large scale

[0035] Dissolve nickel nitrate in ethanol, configure it as nickel oxide, 15g NiO / 100ml ethanol solution, spray and impregnate the prepared solution into 80g carbon nanotubes, place it at room temperature to air dry, and put it in a vacuum oven at a temperature of 80°C Dry under N for 4 hours in a muffle furnace 2 Calcining at 350° C. under the atmosphere for 4 hours to obtain nickel oxide-loaded carbon nanotubes, the nickel-containing carbon nanotubes mentioned in the following steps are the nickel oxide-loaded carbon nanotubes;

[0036] 200g alumina powder, 52g nickel-containing carbon nanotubes, 16g titanium dioxide powder, 50g high-viscosity SB powder, 6g squash powder, 4g citric acid, 7.6g ammonium fluorosilicate, 15g ammonium bicarbonate, 9ml concentration is 66% Nitric acid, add 210ml of water and stir evenly, put it into a kneader and knead for 45 minutes, extrude it into clover strips with a particle size of 1.2mm on the extru...

Embodiment 2

[0041] Preparation of catalyst support:

[0042] The carbon nanotubes loaded with nickel oxide were prepared in the same manner as in Example 1;

[0043] Mix 200g of alumina powder, 52g of nickel-containing carbon nanotubes, 16g of titanium dioxide powder, 50g of high-viscosity SB powder, 6g of scallop powder, 4g of citric acid, 15g of ammonium bicarbonate, 9ml of 66% nitric acid, add 210ml of water and stir well , kneaded in a kneader for 45 minutes, extruded into clover strips with a particle size of 1.2mm on the extruder, air-dried, dried in a vacuum oven at a temperature of 110°C for 4 hours, and dried in a muffle furnace for N 2 The catalyst carrier A2 was obtained by calcining at 550° C. for 4 hours in the atmosphere.

[0044] Preparation of hydrogenation catalyst:

[0045] The preparation method was the same as in Example 1 to obtain hydrogenation catalyst A2-1.

Embodiment 3

[0047] Preparation of catalyst support:

[0048] Same as Example 1, the only difference is that ordinary SB powder is used instead of high-viscosity SB powder to obtain catalyst carrier A3.

Abstract

The invention relates to a hydrogenation catalyst carrier for coal liquefaction oil, a catalyst as well as a preparation method and application of the hydrogenation catalyst carrier and belongs to the field of hydrogenation catalysts. The carrier comprises the following components (counted by 100% of total weight of the carrier): 5-60wt% of carbon nanotube, 32-90wt% of aluminum oxide, 0-8wt% of silicon dioxide and 0-8wt% of titanium dioxide. When the hydrogenation catalyst carrier for the coal liquefaction oil is used for carrying out a hydrorefining reaction for directly liquefying low-grade oil by coal, after the reaction is continuously carried out for 48 hours, the desulfurization rate can reach 99.7%, the denitrification rate can reach 95.1%, and the deoxygenation rate can reach 99.5%; after the reaction is continuously carried out for 168 hours, the desulfurization rate can reach 98.9%, the denitrification rate can reach 94.6%, and the deoxygenation rate can reach 98.6%; the hydrogenation catalyst carrier has high catalytic activity and stability.

Description

technical field [0001] The present invention relates to a coal liquefied oil hydrogenation catalyst carrier, the catalyst and its preparation method and application, and belongs to the field of catalysts, in particular to a hydrogenation catalyst used in the coal liquefied oil hydrogenation refining process, and the carrier for preparing the catalyst , and their respective preparation methods. Background technique [0002] With the accelerated development of the industrialization process, a world-wide oil shortage will be unavoidable. my country's coal resources are the most abundant of the three major fossil energy resources. Making full use of my country's abundant coal resources and vigorously developing coal-to-oil and coal-to-oil technologies is an effective way to reduce the risk of oil shortage. At present, coal liquefied oil technology is the main method to realize coal substitution and coal oil production. Coal liquefied oil technology uses hydrogenation under hig...
