| Abstract/Summary |
A mathematical model of gasification of a large single coal char particle in a carbon dioxide atmosphere was developed. The model formulation took into account the heterogeneous reaction mechanism and the solid phase structure. The pre-exponential factor of the gas-solid reaction of carbon with carbon was estimated in this study whereas the values of activation energies and other model parameters were taken from literature. The model was used to _t the experimental data obtained by TG measurements that were performed using coal char particles prepared by degasification of Slovak brown coal from the coal mine Cígeľ at low and medium temperatures and at atmospheric pressure with different inlet mixtures of carbon dioxide and argon.
