Method for preparing high-efficiency biomass fuel by using graphene

Abstract

The invention discloses a method for preparing a high-efficiency biomass fuel by using graphene. The method comprises a first step of adding 26-28 parts of modified graphene powder into a mixed solution of 20 parts of tetrahydrofuran and 80 parts of absolute ethyl alcohol, carrying out ultrasonic dispersion for 15-25 min, then adding 34-38 parts of a pretreated base material and 6-12 parts of algae-lysing microorganism particles, increasing a stirring rotation speed to 75-85 r / min, carrying out stirring for 35-45 min, then adding 3-5 parts of oleic acid and 2-4 parts of rosin, and continuing stirring for 15-25 min so as to obtain a premix. According to the method for preparing the high-efficiency biomass fuel by using graphene in the invention, graphene is used as the base material for thebiomass fuel and cooperatively used with other auxiliary material; and research results show that the combustion performance and stability of the biomass fuel are significantly improved.

Description

technical field [0001] The invention relates to the technical field of biomass fuel preparation, in particular to a method for preparing high-efficiency biomass fuel by utilizing graphene. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel. Generally, it is mainly agricultural and forestry waste, which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, and it is only used in large stoves in rural areas. It is not allowed to be used in cities. The application of biomass fuel is to use agricultural and forestry waste as raw materials, and through crushing, mixing, extrusion, drying and other processes, it is made into various shapes (such as block, granular, etc.) , a new type of clean fuel that can be directly burned. [0003] The existing Chinese patent document (notification number: CN105132066A) discloses a preparat...

Problems solved by technology

[0003] The existing Chinese patent document (notification number: CN105132066A) discloses a preparation method of biomass fuel, the steps are as follows: 1) collect plant straw, dry the collected plant straw naturally, cut and crush it after drying; 2) cut the straw The powder is dried until the moisture content is within 25%, and then the straw powder is modified to obtain the modified straw powder for use; 3) The following components are proportioned in parts by weight: 85 parts of modified straw powder, 3 parts of calcined kaolin powder, 2 parts of sea mud, 2 parts of sepiolite wool, 5 parts of carbon fiber, 1 part of alumina, 2 parts of tobacco cellulose, 2 parts of modified corn starch, 1.5 parts of antioxidant, 0.5 parts of linear polyethylene part, 0.4 part of silane coupling agent, 0.2 part of ammonium chloride, 0.5 part of dimethyl silicone oil, 0.3 part of styrene monomer, 0.3 part of polyethylene glycol, 2 parts of stabilizer; 4) the material in step 3) Putting it into a molding device and extrusion molding, the biomass fuel has good combustion performance, but the raw material used is a conventional raw material in the field, and the performance is poor, so the present invention innovates it to make the performance of the fuel more excellent

[0004] Existing Chinese patent literature (publication number: CN105132066A) discloses a kind of biomass fuel preparation method, and this composite biomass particle fuel is made by fuel substrate, graphene and coconut shell powder, wherein fuel substrate is made of wheat straw, Wood chips, corncobs, peanut shells, straw, rice husks, camellia husks and cottonseed husks are used as raw materials. Although the fuel contains graphene, graphene is only an auxiliary material and its performance is not optimal.
