Solid catalysts often have a non-uniform internal composition as a result of their method of preparation and working conditions. Such products sometimes command interest because of their better performance. Variables influencing internal distribution during their preparation are considered on the basis of experimental and theoretical studies. Activity and selectivity of these catalysts depend upon the internal distribution of the active species. Activation energies, reaction orders, and apparent diffusion coefficients are masked in relation to their real values, due to the mutual interdependence between mass transport phenomena and chemical reaction.
