Apffel, F

A process is described for manufacturing carbon black and hydrocarbons from discarded tires, comprising: introducing the tires into a reactor; pyrolyzing the tires in a pyrolysis reaction vessel substantially in the absence of artificially introduced oil heating media at a temperature and pressure and for a reaction time sufficient to cause the tires to dissociate into a vapor phase and a solid phase; the pyrolyzing step including directly, internally heating the tires in the reaction vessel using microwave energy; producing carbon black from the solid phase; and processing the vapor phase to produce hyrocarbons.
