Abstract
Systems and methods achieve the conversion of polymer containing material into petroleum products such as hydrocarbon gas, wax, crude oil and diesel. The reactor and its system are designed to subject the polymer containing material to pyrolysis in a way that results in a higher petroleum product yield than conventional existing systems. The system has controls which allow for the heating temperature, rotation of the body, and throughput rate, to be adjusted depending on the reaction time required for the material inside the reactor. The condensing system is able to separate the products into the desired petroleum products by percentage output ranging from wax to crude-like oil to diesel-quality oil.
Claims20
A method comprising:
- heating streams of feedstock of polymer containing materials prior to delivery into a cylindrical reactor body, the cylindrical reactor body comprising an axis perpendicular to a radius of a circular cross section of the cylindrical reactor body;
- applying heat from an external heat source to the reactor body to heat an interior of the reactor body;
- subjecting the heated streams of feedstock to pyrolysis in the heated reactor body;
- rotating the reactor body;
- rotating two or more internal augers within the interior of the reactor body, wherein the augers are each disposed to promote directional movement of materials within the reactor body in the direction from an inlet to an outlet of the reactor body, wherein the augers are positioned to scrape reacted feedstock from a portion of the reactor body adjacent to the augers as the reactor body rotates past the augers and move the reacted feedstock toward the outlet, wherein the augers are offset from the axis of the reactor body, wherein the augers are in a same half of the reactor body;
- utilizing a plug or baffle at an end of the reactor body to reduce heat loss at an exit where char is moved out of the end of the reactor body;
- outputting a portion of the reacted feedstock from the outlet of the reactor body;
- and
- putting a portion of the reacted feedstock through a condensing system to convert the reacted feedstock into petroleum products.
A method comprising:
- processing feedstock of polymer-containing materials prior to reaction by separating the feedstock from other particles of a different weight and size, floating the feedstock in a fluid of known density to separate the feedstock by density, and drying the feedstock;
- heating streams of the feedstock prior to delivery into a cylindrical reactor body, the cylindrical reactor body comprising an axis perpendicular to a radius of a circular cross section of the cylindrical reactor body;
- applying heat from an external heat source to the reactor body to heat an interior of the reactor body;
- subjecting the heated streams of feedstock to pyrolysis in the heated reactor body;
- rotating the reactor body;
- rotating one or more internal rotating augers within the interior of the reactor body, wherein the one or more augers are disposed to promote directional movement of materials within the reactor body in the direction from an inlet to an outlet of the reactor body, wherein the one or more augers are positioned to scrape reacted feedstock from a portion of the reactor body adjacent to the one or more augers as the reactor body rotates past the one or more augers and move the reacted feedstock toward the outlet, wherein the one or more augers are offset from the axis of the reactor body, wherein the one or more augers are in a same half of the reactor body;
- utilizing a plug or baffle at an end of the reactor body to reduce heat loss at an exit where char is moved out of the end of the reactor body;
- outputting a portion of the reacted feedstock from the outlet of the reactor body;
- and
- putting a portion of the reacted feedstock through a condensing system to convert the reacted feedstock into petroleum products.
