Abstract
A pyrolysis apparatus and method for pyrolyzing plastic wastes to form a fuel and generating energy is described.
Claims20
A thermal conversion pyrolysis reactor apparatus including:
- a. a pyrolysis reactor vessel with a heat source to heat plastic material in a first bottom part of the vessel;
- b. a chain conveyer for transporting char and/or plastic to and from the vessel bottom part via at least one chain conveyor inlet and at least one chain conveyer outlet;
- and
- c. a condensing seal located inside and approximate a second top part of the reactor vessel through which decomposed gas travels and wherein the condensing seal prevents entry of oxygen into the vessel and egress of heavier compounds out of the vessel.

A method of completing thermal conversion pyrolysis of plastic by the steps of:
- a. adding plastic to a thermal conversion pyrolysis reactor apparatus including
- i. a pyrolysis reactor vessel with a heat source to heat plastic material in a first bottom part of the vessel;
- ii. a chain conveyer for transporting char and/or plastic to and from the vessel bottom part via at least one chain conveyor inlet and at least one chain conveyor outlet;
- and
- iii. a condensing seal located inside and approximate a second top part of the reactor vessel through which decomposed gas travels and wherein the condensing seal prevents entry of oxygen into the vessel and egress of heavier compounds out of the vessel.
- b. heating the plastic sufficient to cause pyrolysis of the plastic;
- c. collecting the resulting hydrocarbon gas from the reactor vessel.
