Biomass carbonization refers to the process of producing products and by-products from biomass (palm shells, straw and other plant stalks, forestry waste and wood processing residues) through certain processes and chemical reactions. The process of incomplete thermal degradation of biomass in the absence of air or other oxidizing atmosphere to generate carbon and condensable liquids (a mixture of wood tar and wood vinegar, which can be obtained through purification and separation), and other products.

Biomass carbonization technology involves placing biomass raw materials in carbonization equipment and producing biomass carbon through thermal decomposition with a small amount of air.
