چکیده انگلیسی
The kinetics of the complete combustion of propane and methyl ethyl ketone (MEK) at very low concentration in air (0.45 and 0.4 mol% in air, respectively) over Cr-doped ZrO2 (cubic) catalyst (Cr/Zr=0.25) at different temperatures (485-673Â K) in the kinetic control regime have been investigated. The combustion rate data could be fitted well to both the power law and redox (Mars-Van Krevelen) models. From the power law model, the apparent activation energy for the combustion of propane and MEK has been found to be 16.5 and 13.2kcalmol-1, respectively. Among the two models, the redox one, however, gave a better fit to the kinetic data for both the combustion of propane and MEK.
