The present invention is directed to a process for converting waste 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 process generally includes the steps of heating the plastic waste in a hydrogen atmosphere at moderate temperatures and pressures. It has also been discovered that it is important to the process of the invention that under certain conditions of operation that the proportion of high density polyethylene in the plastic scrap feed mixture be kept below a minimum level of about 25 % by weight to achieve complete conversion of the mixture to liquid hydrocarbon materials boiling below 1000 DEG F. |
