Abstract
A method of producing useful fuel fluids from solid plastic waste, including loading solid plastic waste matter into a reaction chamber to define a load, subjecting the load to HTP to extract hydrocarbon mixtures, filtering the hydrocarbon mixtures to extract solid matter, and separating the hydrocarbon mixtures into a light fraction (Cto C) and a heavy fraction (Cto C). The heavy fraction is directed to a first container and the light fraction is directed to a second container. The light fraction is separated into diesel (C-C), gasoline (C-C), and vapor (C-C), and the diesel is directed to a third container, the gasoline is directed to a fourth container, and the vapor is directed to a fifth container. The hydrocarbon mixtures have a carbon number distribution between Cand C. The pressure in the reaction chamber is typically between 0.1 and 10 MPa and the temperature in the reaction chamber is between 350 and 500 degrees Celsius. The plastic waste is selected from the group consisting of PS, PE, PP, and mixtures thereof.
