✦ Synopsis

Pyrolysis of used tires yields oil and pyrolytic carbon black (CB,). The tire pyrolysis process can be performed either in vacua or at atmospheric pressure. The CB, recovered in both processes are different from the commercial carbon blacks used in the tire fabrication. Different spectroscopic methods such as ESCA, SIMS, Auger-spectroscopy and XRD were used to characterize CB, obtained in commercial tire pyrolysis plants operating in ~acuo and at atmospheric pressure. The CB, characteristics were compared with those of rubber-grade carbon black. CB, from vacuum pyrolysis was found to be closer in their chemical nature to commercial carbon black than CBp from atmospheric pyrolysis. Key Words-Vacuum pyrolysis, carbon black, used tire, ESCA, Auger, SIMS, XRD.

## Abstract **Summary:** Pyrolytic carbon black (CBp) has been prepared by rubber crumb pyrolysis under nitrogen flow at 700 °C. The CBp obtained by this process had an average surface area of 81 m^2^ · g^−1^ and was obtained in 43% yield over the starting rubber crumb. Although the CBp surface are
