The continuous depolymerization of e.g. scrap plastics takes place under atmospheric pressure at a temperature of 350 to 400 °C. This creates an oil and a gas phase.
The depolymerization is thus particularly suitable for the thermal pre-treatment of waste plastics and elastomers before a subsequent hydrogenation, gasification or oil firing. The particular advantage lies in the simple and cost-effective conversion of waste plastics from recycling for use in the classical processing scheme of a refinery or similar.
