Description

technical field [0001] The invention relates to a composite heating biochar production equipment and process with automatic temperature control, belonging to the technical field of biomass carbonization. Background technique [0002] Biochar refers to the solid product of bio-organic materials (biomass) after thermal pyrolysis in anoxic and low-oxygen environment, mostly powdery particles. As a new type of clean energy, biochar produced by pyrolysis can be applied to the soil, which can not only increase the organic carbon in the soil, improve fertility, but also increase the sequestration time of carbon in the soil by virtue of its degradation resistance, and alleviate The negative impact of the greenhouse effect on global climate change. In addition, biochar has a large specific surface area and contains more oxygen-containing active groups on the surface, which can adsorb heavy metals and organic pollutants in soil or sewage. Because of its low cost, it is considered by ...
