23 Claims

1. A method for pyrolysis of plastic feedstock comprising post-consumer and/or post-industrial plastics, the method comprising:

directing the plastic feedstock into an internal volume of a reactor vessel; and

pyrolyzing the plastic feedstock in the internal volume of the reactor vessel;

wherein the step of pyrolyzing the plastic feedstock comprises:

using one or more heaters to heat the plastic feedstock in the reactor vessel's internal volume to a temperature of 200° C. or more; and

using the one or more heaters to apply energy at a combined energy density between 0.05 and 0.7 kW per pound of pyrolyzed product produced within the reactor; and

wherein the one or more heaters are configured for applying heat to the plastic feedstock in the reactor vessel at a heat density between 5 and 55 W/in².
