Abstract:

This invention involves pyrolysis of feedstock by introducing carbonaceous feedstock, into a hopper and moving it into a reactor tube enclosed in an oven, generating heat within the oven that is in part transferred to the feedstock, heating it to sufficient temperature to pyrolyze the feedstock into useful volatiles and char. A Venturi system produces a negative pressure directing volatiles into a pyro-gas oven producing heat necessary for pyrolysis and generating useful excess heat. The extruded pyrolysis char has uses including charcoal fuel, soil amendments, and activated charcoal while liquids can be produced for processing into fuels. Excess heat may be used to heat water, steam, and air, may be used in air heating and cooling systems, perform mechanical work with a Stirling engine or generate electricity on the order of 100 kW and higher. The system may be operated in a carbon neutral or even carbon negative manner, allowing sequestration of atmospheric carbon dioxide.
