Abstract: Compact Biomass Conversion Vessel with Integrated Thermal and Chemical Biochar Conditioning This invention describes a compact biomass conversion vessel for producing chemically conditioned biochar from lignocellulosic biomass under controlled oxygen-limited thermal conditions. The vessel defines a biomass treatment chamber associated with a controllable air-inlet arrangement, a thermal conversion region, a vapour-routing passage, a secondary combustion region, a chemical- conditioning subsystem, and a char discharge section. Biomass introduced into the vessel undergoes sequential moisture removal, devolatilisation and carbonisation while oxygen admission is restricted to limit excessive oxidation. Combustible pyrolysis vapours generated during conversion are routed toward the secondary combustion region for heat recovery and reduced external fuel consumption. A selected mineral, alkaline, nutrient-bearing or adsorptive conditioning composition is introduced before, during or after carbonisation. In a preferred operation, conditioning material is applied to residual-hot char after substantial cessation of volatile evolution, thereby promoting deposition or fixation of conditioning species on biochar surfaces while maintaining restricted oxygen conditions.
