Kinetics and modeling of coal gasification were studied in the newly developed fluidized bed thermo gravimetric analyzer. Resulting kinetic parameters, for a moderate heating rate, are in agreement with those found in literature for flash coal pyrolysis. The presented model for the micro fluidized bed reactor encompasses the kinetics of coal pyrolysis as well as the char gasification reaction rate. Effects of temperature on the yield and the composition of the product gas are studied. The model shows good agreement with the experimental results.
