Abstract
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 ZrO 2 (cubic) catalyst ( Cr / Zr = 0.25 ) at different temperatures (485–673 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 13.2 kcal mol - 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.
