Through biomass energy conversion technology, biomass energy can be efficiently utilized to produce various clean energy and chemical products, thereby reducing human reliance on fossil energy and reducing environmental pollution caused by fossil energy costs. Currently, countries around the world, especially developed countries, are committed to developing efficient and pollution-free biomass energy utilization technologies to protect their mineral energy resources and provide fundamental guarantees for the sustainable development of national economies.
Biomass pyrolysis refers to the heating of biomass to over 500 °C without oxidants (air, oxygen, water vapor, etc.) or with limited oxygen supply?, The thermochemical transformation technology of decomposing biomass macromolecular substances (lignin, cellulose and hemicellulose) into smaller fuel substances (solid carbon, combustible gas and bio oil) through thermochemical reaction. The fuel energy conversion rate of biomass pyrolysis can reach 95.5%, maximizing the utilization of biomass energy.
