Zusammenfassung:The first step is kinetic study of the drying and pyrolysis of lignite particles in the range 700–900 ° C, which is characteristic of coal gasification in an autothermal reactor with an inverse thermal wave. Analysis of the experimental data yields a linear kinetic equation for the mass loss of the coal particles in thermal destruction. The simplified kinetic equation is convenient for technological calculations and also for mathematical simulation of the heat and mass transfer in coal gasification.
