Abstract:
A systematic kinetic study of the CO oxidation reaction on the composite MnCeOx catalyst (Mn/Ce =5), varyng Pco and Po2 in the range of 0.00625-0.025, discloses constant empiric orders of 0.55 and 0.35 on Pco and Po2, respectively. Pulse CO oxidation tests suggest the occurence of Mars-van- Krevelen path triggered by the enhanced oxygen mobility of the active MnOx phase, although a formal reaction mechanism uncovers the role and influence of each elementary step on reaction kinetics.
