The pyrolysis of corn stalk with sodium carbonate or potassium carbonate as catalyst was carried out with TGA, and the activation energy distribution at different weight loss of biomass was determined with Distributed Activation Energy Model. Both catalysts could increase the maximum weight loss rate and had obvious effect on pyrolysis results. Under this condition, the temperature at the maximum weight loss rate was 604 K with K2CO3and 607 K with Na2CO3. The activation energy was between 194 and 220 kJ/mole in the weight loss range of 15 to 80%, which indicated that corn stalk pyrolysis is a complex reaction containing a series of cracking of chemical bonds with different activation energies. Catalyst could reduce activation energies by ∼ 20-40 kJ/mole depending on the added amounts.
