  • Patent number: 5070109
    Abstract: A method is disclosed for the recovery of hydrocarbon products from elastomeric products such as discarded vehicle tires and other rubber products. The elastomeric products are immersed in a liquid heat transfer medium and heated to a temperature in the range of from about 575.degree. F. to about 600.degree. F. for a period of from about 0.5 to about 2.0 hours. The process produces a methane-containing gas product, a low boiling fuel oil fraction, a light fraction elastomeric hydrocarbon solid, a heavy fraction elastomeric hydrocarbon solid, and steel cord when steel belted radial tires are processed.
