Partial Syngas and Partial Biochar

In complete contrast to the energy debate and assumed carbon emissions correlation, the product 'biochar' follows a distinctive carbon balance and is disconnected from the typical correlation. Biochar is produced by the slow-pyrolysis of biomass material containing a sufficiently high quantity of lignin ,34], Biochar has the strange attribute of being chemically and biologically inert and stable for thousands of years in soil. When applied to soils the carbon contained in the product is effectively removed from the ecosphere making it a sort of CO2 sink. During the pyrolysis step, volatile hydrocarbons are emitted and could also be upgraded to syngas. Seeing that a proportion of the potentially combustible biomass material is locked within the biochar, a lower overall thermal output compared with Section 12.4.2.2 is present. The carbon sink attribute however leads to a significantly higher CO2 savings potential. For every ton biochar committed to the soil, 3.67 ton of CO2 is removed for the biosphere. Depending on the actions taken at post-Kyoto Protocol summits, biochar might receive double carbon credits as a carbon capture and soil storage (CCSS) mechanism.
