000064408 5203_ $$aThis work focuses on the combustion behavior of raw and demineralized grape pomace and grape pomace doped with 0.1, 0.5, 0.82 (equal to the K concentration in the raw biomass), 3, and 6 wt % K and 0.1, 0.5, 1.08 (equal to the Ca concentration in the raw biomass), 3, and 6 wt % Ca. To identify the individual role of calcium and potassium, the biomass samples were either pyrolyzed in a N2 atmosphere or oxidized in air in a thermogravimetric analyzer (TGA) during non-isothermal runs at 10 K/min from room temperature to a maximum temperature of 1275 K. In all of the cases, the biomass pyrolysis process shows one main stage associated with the volatile matter release. This process is not significantly affected by the mineral content of biomass nor the presence of high K and Ca contents. During combustion in air, the biomass samples show two main distinct stages that are associated with the volatile matter release and the char oxidation. Whereas the main devolatilization stage is not significantly affected by the mineral content of the biomass, the char oxidation stage is shifted to higher temperatures for the demineralized biomass. Potassium and calcium play a different role on the char oxidation process. In general, char oxidation is promoted with increasing the K content, whereas Ca does not significantly influences this process. The TGA results were also used to determine the kinetic parameters of the pyrolysis and combustion processes of biomass in the presence of K and Ca.
