【 摘 要 】

Abstract Kinetics of non-catalytic and Pt-catalysed oxidation of active carbon, selected as a model carbon material was investigated using thermogravimetric analysis (TGA). Investigations were performed in the temperature range from 40 °C to 1000 °C at different heating rates (5–25 °C min–1). The influence of Pt-based catalyst on the combustion kinetics was examined as well. Values of the kinetic parameters, such as activation energy, Ea and Arrhenius pre-exponential factor, A were determined using isoconversional method proposed by Kissinger-Akahira-Sunose. The obtained values were in good agreement with the literature data.
