Abstract
The role of active component distribution among the pores of different size in supported catalysts has been examined. The influence of ''mic rodistribution'' on catalyst pellet activity and stability were studie d. It was shown that the ''microdistribution'' parameter does not affe ct the pellet effectiveness factor in the case of gas-phase reactions. High catalyst stability can be achieved when the fraction of ''microp ores'' does not exceed 30-40%, otherwise the deactivation rate constan ts in small and large pores differ less than 5 times.
