Embodiment 1

[0046] The preparation method of the present embodiment comprises the following steps:

[0047] The preparation of a kind of directional ketosis composite metal oxide catalyst comprises the following steps, as figure 1 Shown:

[0048] (1) Weigh 1.0wt% sodium alginate and 1.0wt% cellulose nanofibers into a beaker, then pour distilled water into the beaker, and configure carbohydrate suspension as a template material;

[0049] (2) Weigh a total of 50g of cerium chloride and manganese chloride, put them into a beaker, add 500mL of deionized water, stir to dissolve them completely, and configure a mixed solution of cerium chloride and manganese chloride, in which cerium ions and manganese ions The molar ratio of cerium chloride and manganese chloride is 9:1, and the total molar concentration of cerium chloride and manganese chloride is 10%;

[0050] (3) Use a pipette to introduce the templating agent suspension into the mixed solution of cerium chloride and manganese chloride, w...

Embodiment 2

[0062] The preparation method of the catalyst is the same as in Example 1, except that in the (3) step of the catalyst preparation method, the volume ratio of the templating agent suspension and the cerium-containing manganese ion mixed solution becomes 5:1; in the (4) step, the oil bath temperature In step (5), the freezing temperature is -15°C; in step (6), the calcination temperature is changed to 600°C, and the time is changed to 6 hours. Finally, black catalyst particles are obtained.

[0063] The application process of the catalyst is the same as in Example 1, except that the temperature is changed to 380° C. and the holding time is 3 hours. Finally, a colorless transparent aqueous liquid was obtained.

Embodiment 3

[0065] The preparation method of the catalyst is the same as in Example 1, except that the volume ratio of the templating agent suspension and the cerium-containing manganese ion mixed solution is changed to 3:1 in the step (3); the step (4) of the catalyst preparation method changes the temperature of the oil bath to to 60°C, and the time was changed to 1h; the freezing temperature in step (5) was -10°C, and the calcination temperature in step (6) was changed to 550°C, and the time was changed to 5h. Finally, black catalyst particles are obtained.

[0066] The application process of the catalyst is the same as in Example 1, except that the temperature is changed to 350° C. and the holding time is 1 h. Finally, a colorless transparent aqueous liquid was obtained.

Abstract

The invention relates to the field of preparation of liquid fuel and chemical products by catalytic conversion of biomass, and discloses preparation and an application of a composite metal oxide catalyst. The catalyst is obtained by the following preparation method: introducing a template agent suspension consisting of sodium alginate and cellulose nanoparticles into a mixed solution of cerium chloride and manganese chloride, forming gel microspheres by an intercalation self-assembly method, and calcining and oxidizing the gel microspheres to form the final catalyst. The catalyst prepared by the method has high selectivity and high yield for ketonization of various biomass pyrolysis products, is cheap and efficient, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of preparing liquid fuel and chemical products through catalytic conversion of biomass, in particular to a composite metal oxide catalyst and its application. Background technique [0002] Today's world is facing the depletion of fossil fuels and various problems of environmental protection. Human beings urgently need to find a sustainable alternative energy source. Biomass energy, as an inexhaustible and inexhaustible energy, has gradually entered the field of vision of mankind, which can be converted into various forms of energy and high-value chemicals. Therefore, vigorously developing biomass energy is of great significance to the progress of human society and the maintenance of civilization. [0003] At present, the utilization of biomass energy at home and abroad mainly includes thermochemical conversion and biochemical conversion. Among them, thermochemical conversion can gasify biomass and convert it into bi...
