Abstract

See full text

A process for the non-oxidative thermal degradation of a rubber containing waste including: transporting the rubber containing waste along a horizontal axis of a hermetically sealed cylindrical reactor including: an inlet and an outlet, one or more thermal reaction zones arranged between the inlet and the outlet, wherein each zone is provided with: one or more heating elements controllable to heat the zone to an operating temperature, and one or more gas outlets for withdrawing volatile gas or gases evolved during the thermal degradation; and a screw auger located within the reactor, the screw augur configured to rotate in both the forward and reverse directions to agitate and transport the rubber containing waste through the reaction zones and to the outlet; heating the said waste, in the one or more thermal zones, to a temperature above the degradation temperature of rubber for a time sufficient to produce the volatile gas or gases and the char product.
