Abstract
The complete catalytic combustion kinetics of isopropanol and ethyl acetate were investigated using a CeO2 catalyst coated on a monolith support. The combustions were carried out at low temperatures and atmospheric pressure, on a fixed-bed monolithic reactor. The Mars and van Krevelen model, power rate law model and Langmuir – Hinshelwood model were used to analyse the experimental results. The differential reactor assumption was used to fit the kinetic models. Due to the low activation energies of the reactions, both the Mars – Van Krevelen and power rate law models showed good agreement between the measured and calculated reaction rates, with the Mars – Van Krevelen model being slightly better.
