Embodiment 1

[0042] A solution is formed by dissolving resol resin with a molecular weight of about 50,000 in acetone, and the concentration of the phenol resin in the solution is 20 wt%. The solution is placed in a temperature-controllable container. There are several small cones protruding downwards at the bottom of the container. There are small holes with an inner diameter of 0.2mm in the cone, and the outer diameter of the tip of the cone is 0.6mm. The viscosity of the solution is adjusted by controlling the temperature, and the liquid level in the container is adjusted to adjust the speed of the liquid flowing out of the container, so that the liquid drops along the cone. The forming tank is filled with a certain level of water. The solution containing phenolic resin drops into the forming tank and sinks, and with the gradual precipitation of acetone, the phenolic resin solidifies when it meets water to form porous spherical particles.

[0043] The spherical particles are washed wit...

Embodiment 2

[0046] Polyacrylonitrile with a molecular weight of about 30,000 is dissolved in N,N-dimethylformamide (abbreviated as DMF) to form a solution, and the concentration of polyacrylonitrile in the solution is 18 wt%. The solution is placed in a temperature-controllable container. There are several small cones protruding downwards at the bottom of the container. There are small holes with an inner diameter of 0.2mm in the cone, and the outer diameter of the tip of the cone is 0.6mm. The viscosity of the solution is adjusted by controlling the temperature, and the liquid level in the container is adjusted to adjust the speed of the liquid flowing out of the container, so that the liquid drops along the cone. The forming pool is filled with ethanol aqueous solution with a certain liquid level, and the ethanol concentration is 15%. The polyacrylonitrile-containing solution drops into the forming pool and sinks, and with the gradual precipitation of DMF, the polyacrylonitrile solidifi...

Embodiment 3

[0050] Polyacrylonitrile with a molecular weight of about 80,000 was dissolved in DMF to form a polymer solution with a polyacrylonitrile concentration of 12 wt%. Other operations were the same as in Example 2 to obtain a carbon-based carrier.

[0051] Put 100 grams of carbon-based carrier in the drum, spray 97ml of water in which active metal components nickel 9.1wt% and manganese 4.5wt% are dissolved, and then dry at 120°C for 3 hours; Roast under protection for 4 hours, and the calcining temperature is 500°C. Catalyst C3 is prepared. The relevant parameters of catalyst C3 are shown in Table 1.

Description

technical field [0001] The invention relates to a spherical catalyst used in the fields of renewable energy and biomass energy, in particular to a biomass pyrolysis liquid ebullating bed hydrodeoxygenation catalyst and its preparation method and application. Background technique [0002] In a broad sense, biomass includes all plants, microorganisms, animals that feed on plants and microorganisms and their wastes; in a narrow sense, biomass mainly refers to various wastes in the production process of agriculture, forestry and animal husbandry. In the previous research and industrialization process, there were many studies on the conversion of sugar, fat and cellulose-based biomass into liquid fuels, and industrial scale production has been formed. However, the conversion of sugar and fat in biomass into energy is facing the embarrassing situation of "competing with people for food and land", and the technology of fully converting and utilizing lignin with higher energy densit...
