Abstract: A polymeric material containing solids in the form of metal and/or cord lumps is partially thermally decomposed to produce a suspension of the polymeric material containing solids in the form of metal and/or cord lumps. Then, the suspension with the solids is directed to a separator, which may be an inclined conveyor, where the solids and the suspension are separated. The separated polymeric material then is thermally decomposed completely. In the separator, the separated solids may be treated by flushing the solids on the conveyor with a preheated solvent, followed by applying steam to the solids and finally drying the solids on the conveyor. Thermal decomposition of the separated polymeric material is completed in a vertical distillation column having a lower liquid phase and an upper vapor-gas phase.

Abstract: An apparatus comprises a reaction chamber provided with a charging hole, a branch pipe for discharging a suspension, and a branch pipe for withdrawing a vapor-gas phase which branch pipe is communicated with a condenser. The apparatus further includes a heater provided with a heat-exchanger for preheating a solvent, said heat-exchanger being introduced into said heater and communicated with said reaction chamber through nozzles adapted for jet feeding of the solvent into the reaction mass.At the outlet of the reaction chamber there is mounted a distillation column communicated with the branch pipe for discharging the suspension and provided in the upper portion thereof with a branch pipe for withdrawal of the vapor-gas phase, while in the lower portion thereof there is provided a branch pipe for discharging a distillation residue.
