Embodiment 1

[0021] The present invention is achieved through the following technical solutions:

[0022] A method for preparing a composite high-energy biomass fuel rod, comprising the steps of:

[0023] (1) Put the straw powder into an oven and dry at 100°C for 20 minutes in the air atmosphere, take it out after drying and cool it quickly to obtain dry straw powder; After dilute hydrochloric acid solution is stirred and cleaned, carry out solid-liquid separation by suction filtration equipment; (3) directly add the sodium carbonate solution of 0.5mol / L to the wet filter residue cleaned in step (2), react 10 minutes under the above-mentioned solution boiling state, After the reaction, use suction filtration equipment to separate; (4) in parts by weight, 100 parts of the filtrate obtained by the separation of step (3) is transferred to the reactor, and then 5 parts of graphene airgel powder, mass fraction 12% Add 5 parts of ammonia water and 30 parts of absolute ethanol successively, stir...

Embodiment 2

[0034] A method for preparing a composite high-energy biomass fuel rod, comprising the steps of:

[0035](1) put the straw powder into an oven and dry at 200°C for 50 minutes in the air atmosphere, take it out after drying and cool it quickly to obtain dry straw powder; (2) dry plant ash with the same quality as the straw powder obtained in step (1) After dilute hydrochloric acid solution is stirred and cleaned, carry out solid-liquid separation by suction filtration equipment; (3) directly add the sodium carbonate solution of 1mol / L to the wet filter residue washed in step (2), react 15 minutes under the boiling state of above-mentioned solution, react Afterwards, separate with suction filtration equipment; (4) in parts by weight, 100 parts of the filtrate obtained by step (3) separation are transferred to the reactor, and then 10 parts of graphene airgel powder, 14% of the mass fraction Add 11 parts of ammonia water and 44 parts of absolute ethanol successively, stir evenly,...

Abstract

The invention discloses a method for preparing a composite high-energy biomass fuel rod. The invention belongs to the technical field of biomass fuel. The invention uses silica aerogel to carry out loading treatment on biomass straw powder, etc. to increase the fuel contact surface area. The organic combination of inorganic and plant straw powder can produce biomass fuel rods with good cohesiveness, high heat energy value, large surface area, high combustion efficiency, and low combustion pollution, which is conducive to the construction of the ecological environment and can be beneficial to the production of fuel. For storage, there is a sufficient combustion contact area and can avoid the fuel from getting damp and regaining moisture, thereby improving its combustion quality, and at the same time avoiding the problem of poor combustion heat value caused by the fuel being damp.

Description

technical field [0001] The invention belongs to the field of biomass fuels, and in particular relates to a method for preparing composite high-energy biomass fuel rods. Background technique [0002] Energy is inseparable from the sustainable survival and development of human beings, the construction and development of social economy and culture, and the health and prosperity of the earth's biosphere. At present, human beings mainly use disposable fossil fuels such as oil, natural gas and coal as energy supply. On the one hand, these energy sources face the problem of resource depletion; Serious pollution, ecological and ecological system balance damage and other problems, and hydrogen as a non-polluting sustainable supply of energy is gradually being recognized by scientists and society. Activated sludge is a general term for microbial groups and the organic and inorganic substances they are attached to. It is an aerobic biological treatment substance and is mainly used to ...
