Kinetics of gasification of char obtained from dried sewage sludge (DSS) with steam and CO2 have been measured in a laboratory fluidized bed (FB) reactor at temperatures between 800 and 950 ºC with steam and CO2. Char was generated in situ in N2 atmosphere, which is important since cooling of char significantly influences its reactivity. The reaction with steam was found to be three to four times faster than the reaction with CO2 depending on the operating temperature. Activation energies were determined for the two reactions. The reactivities with steam and CO2 were found to decrease with increasing char conversion.
