thermal characteristics How to Make Biochar Pyrolysis (gasification) thermal destruction of biomass thermal characteristics exothermic above 250°C an excess of energy is released energy produced is self-sustaining Syngas no extra energy required once ignition occurs as long as feedstock & oxygen are available water H2 CO CH4 Formic Acid Acetic Acid Combustibles Volatiles weight decreases Flammable Tars Resins Condensates low temperature high temperature (less than 500 degrees C) preserves micropores increases char production Charcoal remains (800 - 1000 degrees C) degrades micropores increases biofuel production Danny Day, EPRIDA as temperature increases click to continue

How to Make Biochar industrial scale Pronatura Plus, South Africa continuous feed charcoal ABRI, Ontario, Canada Shivam Enterprises West Bengal, India Rice Hull Pyrolyzer India 2 Chamber Conversion Reactor MSW is fed by “charging unit” into upper chamber where it is gasified. Gases leave reactor through outlet and combusted in burn chamber. MSW falls into lower chamber where it forms char & combustible gas. Gas is burned with air entering through slits. Charcoal is discharged at the bottom. 50 dry tons / day Modular construction Transportable Designed for wood wastes Produces bio-oil, charcoal, heat 1 dry ton / day Towed on trailer to biomass Simple, Fully Automated Broad range of applications Processes agricultural wastes Produces bio-oil, charcoal, heat Continuous pyrolysis of farm residues into green char performs like charcoal from wood, at half the cost. Machinery is modest, requires minimal energy (8kw electric), with no toxic emissions. Run by two persons, produces 4 tons a day. modern pyrolysis has little in common with traditional ways to make charcoal click to continue
