ABSTRACT:
Pyrolytic apparatus for recycling discarded rubber tires and the like that includes an auto clave shell that is closed at both ends to provide a closed vessel and has an interior refractory lining enclosing a reactor chamber and in conjunction with the vessel forms a gas-oil separation chamber surrounding the lining, heat exchangers within the lining, burners exterior of the vessel for conducting heat to the heat exchangers, a compressor for withdrawing pyrolytic gas given off by the pyrolytic decomposition of tires in the reactor chamber and conducting it to a recovered gas storage tank and a line for conducting oil given off by the decomposition of tires in the reactor chamber to an oil storage tank. The vessel walls are of a sufficiently lower temperature than that in the reactor chamber that the oil condenses on the vessel walls. The vaporized oil and recovered gas passes through cracks between the refractory lining blocks to move from the reactor chamber to the gas-oil separation chamber, a pop-off safety valve on the vessel and opening to the last mentioned chamber being provided to prevent the pressure in the vessel increasing above a preselected level. Non-fluid by products such as carbon black, steel and fiberous materials are recovered from the reaction chamber after the tires are decomposed.
