Samples from a used automotive tire were subjected to subcritical and supercritical extraction with water. Supercritical water was found to be almost as effective as supercritical n-pentane. For a 9-mm cube sample the rate of supercritical extraction with water followed a first-order kinetics with an activation energy of 170kJ/mol. Dynamic TGA data for 0.13-0.35 mm samples showed that pyrolysis at temperatures of 690-730 K had almost the same activation energy as did supercritical extraction with water.
