Abstract:
1. A method for the pyrolysis of feedstock comprising the steps of A) selecting a feedstock suitable for pyrolysis; B) supplying said feedstock into an open feed hopper; C) introducing said feedstock into a reactor tube, and moving said feedstock therethrough by means of a rotating primary auger; D) heating said feedstock within said reactor tube to a sufficient temperature such that pyrolysis of the feedstock occurs to produce volatiles and carbonized feedstock that react at high temperatures; E) collecting the residual carbonized feedstock exiting the reactor tube by gravity into an inner char receptor vessel wherein a Venturi effect is created by a Venturi system driven by a pressure air blower; F) extracting the char through a char channel via a char auger that, together with said char receptor vessel, delivers said char to a final char output hopper while blocking the flow of air inward or pyro-volatiles outward; G) directing said volatiles by said Venturi effect through a volatiles transfer region and into a combustion chamber or a gas oven that provides direct thermal contact with said reactor tube such that heat generated by combusting said volatiles within said combustion chamber or gas oven is transferred to said feedstock in said reactor tube through the wall of said reactor tube to provide heat for pyrolysis; and H) periodically reducing the rotational rate of the primary auger and/or increasing the air from the pressure air blower or a burner blower to move the flame front to the region connecting the exit of the reactor tube with the combustion chamber or gas oven so as to burn out any carbon or tar deposits in the volatiles transfer region.
