Reproducing method and waste tire derived products of carbonaceous material from the waste tire

摘要

The invention relates to recycled rubber produced by a process comprising the steps of: a) shredding cleaned rubber tires into shreds less than 2″ long; b) pyrolyzing the shreds in a reaction chamber of a thermal processor in a first anaerobic environment to produce a char; c) drawing off volatile organics from the reaction chamber; c) removing the char from the reaction chamber; d) cooling the char in a second anaerobic environment; e) removing metal and textile components from the char to obtain pyrolytic carbon black; f) milling and sizing the pyrolytic carbon black so obtained into particles of 325 mesh size or smaller; and, g) utilizing the pyrolytic carbon black from the previous step in a polymerization process that produces said recycled rubber. It also relates to the high quality pyrolytic carbon black recovered from this process.
