Abstract
Disclosed herein are methods for pyrolysis of plastic feedstock comprising post-consumer and/or post-industrial plastics. In various implementations, the methods include 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.
Claims28
A method for pyrolysis of plastic feedstock comprising post-consumer and/or post-industrial plastics, the method comprising:
- melting the plastic feedstock to produce at least semi-molten feedstock;
- directing the at least semi-molten feedstock into an internal volume of a reactor vessel;
- and
- pyrolyzing the at least semi-molten feedstock in the internal volume of the reactor vessel;
- wherein the step of pyrolyzing the at least semi-molten feedstock comprises:
- using one or more heaters to heat the at least semi-molten feedstock in the reactor vessel's internal volume to a temperature between 200° C. and 1,000° C.;
- and
- operating the reactor to pyrolyze the at least semi-molten feedstock for a cumulative period of 324 hours or more during a time period of 360 hours.
