<p>The invention relates to a multi-stage, energy self-sufficient and continuously operating pyrolysis method for the fractionated recovery of valuable substances and energy from pourable, cross-linked organic compounds of high molecular weights, in particular from granules of used tires, sealing profiles and other plastic materials, and to an apparatus for carrying out said method. In order to develop an energy self-sufficient, continuously operating pyrolysis method for pourable organic granules according to the preamble, it is proposed according to the invention that the granules gravimetrically pass through a vertical, multi-stage pyrolysis reactor from the top to the bottom, wherein said granulates are heated to process temperatures that can be incrementally set to different values ranging between 300 and 1,200ºC and are pyrolyzed. A subsequent fractionated condensation of the pyrolysis vapors causes a recovery of oil and gas compounds, and a downstream motor-based use of the pyrolysis gas generates the energy required for the pyrolysis process.</p> |
