Abstract:
1. A method for processing wastes containing rubber into useable substances comprising: a. heating the wastes in the presence of a hydrocarbon solvent and an inert gas to a temperature of approximately 100° C. under a pressure of approximately 0.1 to 0.2 MPa while simultaneously collecting a liquid fraction comprising engine-grade fuel; b. thereafter heating the wastes in the presence of the hydrocarbon solvent and the inert gas to an approximate temperature of 200° C. under an approximate pressure of 0.1 to 0.2 MPa while simultaneously collecting a liquid fraction comprising a hydrocarbon based solvent; and c. thereafter heating the wastes in the presence of the hydrocarbon solvent and the inert gas to temperatures above 200° C. at approximately 0.1 to 0.2 MPa while simultaneously collecting a liquid fraction comprising boiler-grade fuel.
