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.
