WebBiochar is a charcoal-like product that is created by heating biomass to very high temperatures in a low-oxygen environment—a process known as pyrolysis. Converting biomass to biochar slows the decaying process and locks stored carbon in place, in turn slowing down its release back into the atmosphere. [ 1] WebCharacteristics of Biochar From a physical point of view, biochar has a low bulk density due to its porous structure, leading to a high specific surface area and a high water holding capacity. From a chemical point of view, the most striking feature of biochar is its poly condensed aromatic structure caused by dehydration during thermochemical ...

WebBiochar Production from Various Feedstock. Biochar production technology is highly dependent on both the pyrolysis process and the characteristics of biomass. In general, pyrolysis has been performed at a high temperature with limited oxygen, but heating conditions such as operating temperature, heating rate, and residence time are inconstant. WebProduced Biochar Characteristics. The feedstocks produced biochar yields of 34% to 37% (Table 2). Increasing the pyrolysis temperature from 300 to 500 °C resulted in a reduction in biochar yield from 41% to 30.7%. Moreover, results showed that 59% of the initial wood mass was lost at 300 °C and another 10.3% was lost at 500 °C.
