Tire pyrolysis systems and processes are provided which include feeding tire shreds to a pyrolysis reactor, pyrolyzing the shreds in a pyrolysis reactor to produce a hydrocarbon-containing gas stream and carbon-containing solid, removing the carbon-containing solid from the reactor, directing the hydrocarbon-containing gas stream into a separator, contacting the hydrocarbon-containing gas stream with an oil spray in the separator thereby washing particulate from the hydrocarbon-containing gas stream and condensing a portion of the gas stream to oil, removing and cooling the oil from the separator, directing non-condensed gas from the gas stream away from the separator, and directing a portion of the cooled oil removed from the separator to an inlet of the separator for use as the separator oil spray. A process is also provided in which solids from the pyrolysis reactor are directed to an auger having a pressure which is greater than the pressure in the pyrolysis reactor, and in which non-condensed gas from the gas stream after condensing a portion of the gas is directed to at least one burner in heat exchange relation with the pyrolysis reactor, and burned to heat the reactor and generate an effluent flue gas, a portion of which effluent flue gas is cooled and injected into the auger which is a trough auger in one embodiment.

A shoe press according to claim 9, in which the high molecular weight elastic materials of said hard portion and said portion having less hardness are identical.11. A shoe press according to claim 9, in which the high molecular weight elastic materials of said hard portion and said portion having less hardness have identical hardness properties, and in which the difference in hardness between said portions is due to said voids.12. A shoe press according to claim 9, in which said voids are independent of one another, whereby cracks are prevented from propagating from one void to other voids.13. A shoe press according to claim 9, in which said voids are formed by hollow elements from the group consisting of hollow fillers and hollow microcapsules.14. A shoe press according to claim 9, in which said voids are formed by hollow fillers constituting from about 0.5% to 50% of the weight of said portion having less hardness.15. A shoe press according to claim 9, in which the diameters of said voids are in the range from 10 to 100 &mgr;m.16. A shoe press according to claim 9, in which said voids are air bubbles present in an amount in the range of approximately 0.2% to 30% of the volume of the material of said portion having less hardness.
