Front Plant Sci 13:911846. Web(i.e., reaction time more than 15 min) in producing biochar. Typical pyrolytic carbonization processes require the raw feed-stock biomass to be dry before the biomass decomposes ther-mally from the added heat, resulting in carbonaceous solids called biochar and combustible gases. The gas yield from py-rolysis ranges from 13 to 25 % by weight.
