ABSTRACT:
The present invention is directed to a process for the conversion of waste plastics and scrap rubber to a high quality synthetic crude oil which can be separated by fractionation into gasoline, diesel fuel and gas oils suitable as a feedstock to a catalytic cracker. The process generally includes the steps of heating the plastic scrap and scrap automotive tires in a hydrogen atmosphere at moderate temperatures and pressures. It has also been determined that the polymeric waste material must be present in combination with the scrap automotive tires to attain conversion of the scrap automotive tires to liquid hydrocarbon.
