Abstract
The role of active component distribution among the pores of different size in supported catalysts has been examined. The influence of “microdistribution” on catalyst pellet activity and stability were studied. It was shown that the “microdistribution” parameter does not affect the pellet effectiveness factor in the case of gas-phase reactions. High catalyst stability can be achieved when the fraction of “micropores” does not exceed 30–40%, otherwise the deactivation rate constants in small and large pores differ less than 5 times.
