This paper reports the kinetics of coal char conversion. An experimental technique of simultaneous thermal analysis is presented. The obtained results are compared with other studies of char kinetics reported in the literature. The analysis shows that thermogravimetric method enables to determine input parameters for mathematical modeling of thermo-chemical conversion in an entrained flow reactor.
