摘要：

The aim of this study was to describe the methodology of semi-quantitative characterization of carbonaceous material oxidized under mild thermal conditions. Infrared spectroscopic analysis was applied to the determination of chemical changes induced by oxidation. A curve fitting model has thus been developed to evidence the evolution of specific chemical groups during treatment. The possibility to follow mechanisms and kinetics of carbonaceous char oxidation through data obtained by this model has been demonstrated. (C) 1998 Elsevier Science Ltd. All rights reserved.
