Testing the assumption of surface homogeneity in modeling catalytic reactions

Two techniques are described, which can be used to test the validity of the assumption of a uniform surface when modeling the kinetics of gas-solid catalytic oxidation reactions. These are applied to data previously obtained for the oxidation of toluene and o-xylene over a vanadium oxide catalyst. O...

Description
Summary:Two techniques are described, which can be used to test the validity of the assumption of a uniform surface when modeling the kinetics of gas-solid catalytic oxidation reactions. These are applied to data previously obtained for the oxidation of toluene and o-xylene over a vanadium oxide catalyst. On the basis of these data, the introduction of terms accounting for nonuniformity of the catalyst surface is not warranted and the assumption of a homogeneous catalyst surface is shown to be adequate.
