ABSTRACT:
The present invention is directed to a method for converting municipal waste containing plastics 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 presence of cellulosic and proteinaceous waste materials in the municipal waste does not inhibit the process of the invention for converting the municipal waste into a synthetic crude oil. The process generally includes the steps of heating the municipal waste in a reaction gas, of a mixture of hydrogen sulfide and hydrogen or hydrogen at moderate temperatures and pressures.
