Abstract:
The coefficient of oxygen diffusion and the activation energy for diffusion have been measured for the series of oxide catalysts of selective oxidation of organic compounds (Sm-Mg-O, Sm-O; V-P-O, Sn-Sb-O, Sn-Bi-O, Fe-Sb-O, Bi-Sb-O). The rates of oxygen diffusion under catalytic conditions have been compared with the reaction rates. For all studied systems (except Sm-O and Sm-Mg-O) at optimal operative temperatures the maximum rate of oxygen diffusion is sufficient to carry out the reactions of selective oxidation through rapid oxygen diffusion in the surface layers.
