ABSTRACT:
A pyrolysis batch process is disclosed for recycling hydrocarbon containing used material such as plastics including ABS, polystyrene styrene and other non-chlorinated hydrocarbons, car fluff such as solid plastics, foam plastics, fabrics and the like, and more particularly scrap tires so as to obtain useful light oil and fuel gases. Used tire cuttings are loaded into a rotatable reactor which is closed, evacuated, rotated and heated until exothermic reaction is initiated. The reactor internal pressure is then allowed to increase to and is regulated within the range of atmospheric pressure and above. Upon continuing reactor rotation and heating, condensable hydrocarbon vapors and gaseous hydrocarbons are produced. The vapors are condensed into oil while the gaseous hydrocarbons are used as a fuel for reactor heating. At the end of the batching operation, the reactor is air cooled prior to reactor opening and unloading of the solid residues namely carbon black residues, wire mesh and/or some other fibrous materials such as Kevlar.RTM. having a high temperature decomposition point.
