Kinetics of the Thermal Degradation of Granulated Scrap Tyres: a Model-free Analysis

Blog Article

Pyrolysis is a color touch 7/97 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 click here and pre-exponential factor for the degradation of GST were calculated.A comparison with the results obtained by other authors was made.DOI: http://dx.
