<p>A process for upgrading plastic material containing inorganic filler or reinforcement material for use as feedstock in a partial oxidation gas generator for the production of raw synthesis gas, fuel gas, or reducing gas. The plastic material is granulated and mixed with water to produce the plastic sludge. The plastic sludge is preheated at a temperature of about 350 °F to 475 °F in the absence of air in a closed system. The preheated plastic sludge is then hydrothermally treated at a temperature of about 450 °F to 650 °F and at a pressure above the vapor pressure of water at that temperature. The hydrothermally treated plastic sludge is cooled, degassed, and mixed with carbonaceous fuel, to produce a slurry. The slurry is then reacted by partial oxidation to produce said synthesis gas, fuel gas, or reducing gas.</p> |
