Abstract:
1. A process for the conversion of biomass material into charcoal or carbonized charcoal, comprising the steps of: (a) sealing said material in an enclosed container having a proximal end and a distal end, a valved air entry orifice in the proximal end for introducing air at the proximal end of said container and (b) pressurizing said container with air or oxygen, then initiating a directed flow of air or oxygen into said container at said proximal end through said air entry orifice in the proximal end toward the distal end and out of said container at the distal end; (c) heating said material with said heater to cause it to ignite and burn while continuing said flow of air or oxygen, then ceasing operation of said heater after ignition of said material; (d) continuing said flow while controlling the flow and pressure within said container in a proximal-to-distal end flow by regulating air or oxygen intake through the air entry orifice in at said proximal end of the container and exhaust of combustion bases gases through the gas exit orifice at said distal end; (e) continuing the proximal-to-distal end flow until carbonization of said material is complete.
