Samplesfrom a used automotive tire were subjected to subcritical and supercritical extraction with water. Supercritical water wasfound to be almost as effective as supercritical /t-pentane. For a 9-mmcube sample the rate of supercritical extraction with water followed a first-order kinetics with an activation energy of 170kJ/mol. DynamicTGAdata for 0.13-0.35 mmsamples showedthat pyrolysis at temperatures of 690-730 K had almost the same activation energy as did supercritical extraction with water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
