Abstract: | The destructive distiliation of rubber tire samples was studied by thermogravimetry, differential scanning calorimetry, combustion calorimetry, and mass spectroscopy. The decomposition reaction was found to be exothermic and produced a mass loss of sixty-five percent. The products from the distillation process were a solid residue with a heating value of about ?3 × 107 J kg?1. a liquid with a heating value of about ?4 × 107 J kg?1, and a combustible gas of undetermined heating value. The gas evolution curves which were obtained indicate that a variety of organic materials are evolved simultaneously during decomposition of the rubber polymer. |
