Problems solved by technology

[0004] The carbonization equipment in the prior art can carbonize biomass to obtain four products: biomass charcoal, biomass gas, wood vinegar and wood tar. However, due to insufficient technological research, targeted production cannot be achieved. A certain product, and most carbonization equipment with biomass charcoal as the main product did not treat the subsequent biomass gas tail gas, causing environmental pollution

Description

technical field [0001] The invention belongs to the technical field of biomass utilization, and in particular relates to a biomass carbonization process and system with high carbon yield. Background technique [0002] Biomass energy is stored in organic matter that can grow, such as plants, animals and microorganisms, and it is converted from solar energy. Biomass energy resources are relatively abundant on the earth, and it is a kind of harmless energy. The earth produces 173 billion tons of matter through photosynthesis every year, and the energy contained in it is equivalent to 10-20 times of the world's total energy consumption, but the current utilization rate is less than 3%. [0003] Biomass energy has the following characteristics: (1) Renewability: Biomass energy is a renewable resource. Biomass energy can be regenerated through photosynthesis of plants. It belongs to renewable energy like wind energy and solar energy. It is rich in resources and can guarantee ener...
