Abstract
Zeolites Y ion-exchanged with cation of transition metals were tested for oxidation reaction.
For the oxidation of carbon monoxide by Zeolite Co（II）Y, Fe(II)Y, Ni(II)Y, Cr(III)Y and Mn(II)Y, rate equations obtained are as follows.
Vco = k P1oP0CO for Ni（II）Y
Vco = k’ Pno2P0CO Cr（III）Y, Fe(II)Y, Co(II)Y
Vco = k" P1o2P3CO Mn（II）Y
Mechanism of Twigg-Redeal type which carbon monoxide adsorbe chemically and oxygen arrive on the surface as gas phase was also proposed.
Activation energies of the above transition metal Zeolites were measured at the temperature range of 200-400 ℃ to discuss the mechanism.
