  • Recovering carbon black from waste rubber
    Patent number: 3978199
    Abstract: Carbon black is recovered from vulcanized waste rubber such as automobile tires or other articles by reacting pieces of the rubber with an aromatic oil solvent in a stirred reactor at 500.degree.-700.degree.F temperature and about 25-100 psig pressure for 0.5-2 hours residence time. The resulting solids-liquid mixture is processed to remove solids, and the resulting solid product is then dried, screened and chemically treated to recover the carbon black in dry powder form. The remaining solvent oil is also recovered and a portion reused in the process.
