Problems solved by technology

Therefore, a large amount of biomass cannot be processed by the most direct and simple way of burning / carbonization, resulting in waste of biomass energy
At present, some new methods have emerged for the conversion and treatment of biomass, such as gasification, liquefaction, pyrolysis, etc., but such treatment methods usually have high equipment costs and are not suitable for large-scale promotion of biomass conversion or treatment. question

Abstract

The invention discloses a method and device for producing a carbon material by non-pollution biomass microwave anaerobic carbonization. The method comprises the following steps that: in an inert gas protection environment, high-temperature pyrolysis treatment is performed on biomass by using microwave plasma formed by microwaves and metal discharge to realize anaerobic carbonization of the biomass, and a carbon material and a graphene material are prepared; and harmful substances in tail gas generated in the anaerobic carbonization treatment process of the biomass are adsorbed by utilizing a conductive carbon material, and the adsorbed harmful substances are subjected to high-temperature cracking treatment by utilizing microwave plasma formed by microwaves and metal discharge, so that the purification of the tail gas is realized. According to the method and device of the invention, not only can high-efficiency, pollution-free and zero-emission treatment of the biomass be realized, but also recycling of the biomass can be realized.

Description

technical field [0001] The invention relates to the technical field of biomass carbonization, in particular to a method and device for producing carbon materials by microwave anaerobic carbonization of pollution-free biomass. Background technique [0002] Biomass is one of the important energy sources for human survival. In human production and life, a large amount of lignin such as straw and trees in the process of agricultural and forestry production, night waste from agricultural product processing, agricultural and forestry waste, and animal husbandry are usually produced. Biomass such as poultry manure and waste in the production process. The direct incineration of these biomass materials will cause a large amount of harmful substances and emissions of harmful gases, causing environmental pollution and waste of energy. [0003] When biomass is treated by direct combustion or carbonization, it is inevitable that some harmful substances will be formed and harmful tail ga...
