The effect of cyclic operation on heterogeneous catalytic reaction with educt inhibition
In heterogeneous catalytic reactions, the rate of adsorption often falls extremely rapidly with increasing coverage. The reason can be a strong inhibition by a reactant or an increasing activation energy with coverage. Adsorption/desorption models based on those assumptions predict a considerable rate improvement for cyclic operation. This was demonstrated by exptl. study of the heterogeneous catalytic addn. of HOAc to C2H4. [on SciFinder (R)]
