Abstract: Pyrolytic reprocessing of plastic, rubber, or other hydrocarbon materials in which the resultant pyrolysis gas is brought in a cooling stage to a temperature just above the freezing point of water and to a pressure of approximately 0.8 to 1.4 bar of overpressure. The resultant condensate is then separated and heated to a normal storage temperature and the super atmospheric pressure on the condensate reduced to atmospheric pressure. The gas produced thereby comprising C.sub.4 hydrocarbon compounds is supplied to the pyrolysis process as special product gas. By means of this provision, the proportion of aromatic compounds in the pyrolysis gas is raised substantially.
