<p>The procedure consists of subjecting the tyre rubber to thermal destruction or depolymerisation in a medium at a controlled pressure and temperature, adding 1-3 wt.% of calcium oxide to the tyres before the process is started. The thermal destruction process is carried out at a temperature of 100-130 degrees C in an atmosphere enriched with saturated water vapour, and the substances obtained from the process are drawn off by forced suction and compressed. The installation for carrying out the procedure consists of a thermal destruction unit (3) with a top hatch for feeding in the tyres to be processed and calcium oxide from a container (4) and doser (5), a hopper at the bottom for evacuating the residue from the process, and a duct (14) with an automatic valve (39) for drawing off the combustible substances.</p> |
