✦ Synopsis

Pyrolytic carbon blacks (Cq) were obtained by vacuum pyrolysis of used tires in a batch reactor at a total pressure ranging from 0.3 to 20.0 kPa, and temperatures ranging from 420 to 700°C. CBp differ from commercial carbon blacks used initially in the tire fabrication.

A series of commercial carbon blacks with different surface areas and structures and CB, obtained under different pyrolysis conditions were characterized using ESCA and SEM techniques to investigate the effect of the pyrolysis conditions on the chemical nature of the surface of CB,.

## 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
