| Summary: | <p>Pyrolysis is a technology with a promising future in the recycling of scrap tyres. This paper determines the thermal decomposition behaviour and kinetics of granulated scrap tyres (GST) by examining the thermogravimetric/derivative thermogravimetric (TGA/DTG) data obtained during their pyrolysis in an inert atmosphere at different heating rates. The model-free methods of Friedman, Flynn-Wall-Ozawa and Coats-Redfern were used to determine the reaction kinetics from the DTG data. The apparent activation energy and pre-exponential factor for the degradation of GST were calculated. A comparison with the results obtained by other authors was made.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.19.4.2947">http://dx.doi.org/10.5755/j01.ms.19.4.2947</a></p> |
