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. WebAug 1, 2024 · This can be attributed to the high thermal capacity of water (4.184 J cm −3 K −1), which could suppress the decreasing effect of biochar on soil thermal capacity at high SWC. The increase in air filled pores after biochar application can also lead to isolation of contacts among soil solid particles and water.
