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.
