Abstract: An apparatus for batch compression of tires has a support frame for supporting and aligning a plurality of tires in a generally axially aligned position. A mechanism for securing the plurality of tires is provided, as well as a ram member for axially compressing the tires which includes a protrusion for engaging a central orifice of each of the tires for guarding against misalignment of the tires. Also set forth is a method for batch pyrolysis of tires comprising the steps of first baling a plurality of tires together in a compressed cylinder having an orifice extending through the central portion. Next, the compressed cylinder is placed in a pyrolysis oven such that the heat can circulate through the central orifice and about the compressed cylinder. Thereafter, the material is batch pyrolized to produce useful by-products and retain a greater portion of the char material.

Abstract: A method for reclaiming carbon black from scrap rubber material including the following steps. The scrap rubber material is first pyrolyzed to produce a char material that contains a mixture of agglomerated or cluster particles which consist of agglomerations of finer carbon black particles and unitary grit like particles. The agglomerated particles are then selectively de-agglomerated by agitation of the char material into the finite component particles of carbon black. These finite component particles are then separated from the unitary particles to obtain a final carbon black which is comparable to commerical grade carbon blacks.
