Abstract

The present work aimed at developing isothermal calorimetric technique for kinetics analysis of low-temperature coal oxidation, based on non-steady heat generation rate measured by using sealed vessels in the calorimeter. Isothermal calorimetric analyses on the oxidation of two coals were conducted at five incremental temperatures of 30–70 °C. The measured heat generation rates versus time were interpreted by fitting with simple kinetic models. The results showed the first-order kinetics fairly well representing the heat evolution after early hours (~12 h) of the reaction while Elovich equation roughly following the heat evolution at the early stage. Empirical expressions, considering the overall oxidation as two reaction pathways, chemisorption and first-order direct burn-off reaction, can describe the heat evolution over entire process. While fitting with empirical expressions provides little kinetic information, fitting the measured heat generation rate after early hours with the first-order kinetics yields the apparent kinetic parameters and the heat of reaction of low-temperature coal oxidation. The parameters are valuable for using simple kinetic model to evaluate or numerically simulate the self-heating of coals in terms of engineering applications.
