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.
Claims25
A system that converts polymer containing materials into petroleum products, the system comprising:
- a feedstock receiver into which feedstock is fed from one end and from which the feedstock exits from the other end, wherein the feedstock receiver further comprises a single or double screw extruder to pre-melt the feedstock and to feed the melted feedstock into a reactor body;
- the reactor body to accept the feedstock from the receiver and to heat the feedstock to a reaction temperature, wherein the reactor body comprises a horizontal cylindrical body with internal augers;
- controllers that adjust rotation of the reactor body, adjust an incline of the reactor body between 0 and 30 degrees, operate the internal augers to counter-rotate relative to each other, and operate the internal augers to move char out of the reactor body;
- a heating source applied along one or more sides of the rotating body to adjust temperatures inside the reactor body;
- a condensing system to cool vapor products from the reactor body into liquids and to capture non-vapors;
- feedback controls that provide guidance as to conditions required to vary yields of desired products from the system;
- and
- a plug or baffle at the end of the reactor body to reduce heat loss at an exit where the char is moved out of the end of the reactor body.
A system that converts polymer containing materials into petroleum products, the system comprising;
- a shredder or grinder to shred or grind the polymer containing materials into a smaller size;
- a feedstock separator that separates the shredded or ground materials by weight and size;
- a feedstock container in which the polymer containing materials are separated by density using fluids of known density;
- a feedstock dryer in which reaction materials are dried;
- a feedstock receiver into which feedstock is fed from one end and from which the feedstock exits from the other end, wherein the feedstock receiver further comprises a single or double screw extruder to pre-melt the feedstock and to feed the melted feedstock into a reactor body;
- the reactor body to accept the feedstock from the receiver and used to heat the feedstock to a reaction temperature, wherein the reactor body comprises a horizontal cylindrical body with internal augers;
- controllers that adjust rotation of the reactor body, operate the internal augers to counter-rotate relative to each other at chosen rates, and operate the internal augers to move char out of the reactor body;
- a heating source applied along one or more sides of the reactor body;
- a condensing system to cool vapor products from the reactor body into liquids and to capture non-vapors;
- and
- a plug or baffle at the end of the reactor body to reduce heat loss at an exit where the char is moved out of the end of the reactor body.

- a condensing system to cool vapor products from the reactor body into liquids and to capture non-vapors wherein the condensing system comprises several condensers, each with a specific use, including a first condenser that is used as a reflux column, a second condenser that is used to cool vapor into liquids and a third condenser that is used to condense a portion of the vapor into a liquid stream at a set boiling range;
- feedback controls that provide guidance as to ideal conditions required to vary the yields of the products;
- and
- a plug or baffle at the end of the reactor body to reduce heat loss at an exit where the char is moved out of the end of the reactor body.
