<p>1. Process for the hydrogenative reprocessing of carbon containing waste materials, with the exclusion of a process for hydrocracking of waste tires in the presence of a catalyst of an iron compound and an auxiliary catalyst of metal compounds of the group Cr, Mo, W, Se and Te, based on a synergistic catalyst action with sulfur, by treatment of the waste materials with hydrogen und/or hydrogen transferring solvents (hydrogen donor solvents), characterized in that mixtures of carbon containing waste materials of synthetic respectively predominantly synthetic origin are reacted with hydrogen and/or hydrogen containing gases at a temperature of 200-600 degrees C, preferably at a temperature of 200-540 degrees C, at a pressure of 30-500 bar, preferably of 50-450 bar and a residence time of 1 minute to 8 hours, preferably of 15 minutes to 6 hours and in the case of reaction with a hydrogen-donor-solvent at a temperature of 75-500 degrees C, preferably of 80-480 degrees C and a pressure of 1-300 bar.</p> |
