Abstract

The invention belongs to the technical field of biomass charcoal, and discloses a method for directionally producing biomass charcoal by the microwave catalytic pyrolysis of biomass. The method comprises the following steps: selecting agricultural wastes, bamboo charcoal, wood charcoal, grass charcoal or activated carbon as raw materials; smashing the raw materials by a pulverizer, and sieving toobtain powdered carbon; adding thermosetting adhesive into the powdered carbon, and evenly mixing; then, carrying out cold drying; evenly mixing the powdered carbon, metal salt or metal oxide catalyst, then, heating, carrying out pyrolysis for 40-60min in a microwave reactor to obtain a gas product and a solid product; quickly condensing the obtained gas product under a condition of -4 to 10DEG C,directly condensing a coagulable part into liquid-phase high-quality biomass oil, and taking non-condensing gas as high calorific value gas fuel. According to the method, the agricultural wastes aretaken as the raw material so as to be favorable for environment protection and the reuse of agricultural wastes. A preparation process of the biomass charcoal materials does not generate tar.

Description

technical field [0001] The invention belongs to the technical field of material charcoal, and in particular relates to a method for directional production of biomass charcoal by utilizing microwave catalytic pyrolysis of biomass. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Biomass refers to various organisms formed through photosynthesis, including all animals, plants and microorganisms. Biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy. It has always been one of the important energy sources for human survival, and it is the fourth largest energy source after coal, oil, and natural gas. plays an important role in the system. However, in the prior art, due to the thermochemical reaction of biomass, a large amount of tar is produced, which increases the difficulty of the preparation process of biochar; meanwhile, the continuous increase of agricult...
