Differences between combustion and oxy-combustion of corn and corn-rape blend using thermogravimetric analysis

The activation energy obtained from corn (153.0 kJ/mol) combustion was lower than that obtained from corn oxy-combustion (168.6 kJ/mol). However, corn-rape blend oxidation was more favourable in the presence of CO2 (E ~ 155.3 kJ/mol) than in N2 (E ~ 155.9 kJ/mol). Both Vyazovkin and Ozawa-Flynn-Wall methods yielded similar results.
