摘要：

The problem of modelling of the intraparticle diffusion affected by the time-on-stream catalyst decay is considered. Independently of the value of n, a cross -effect is attained consisting in a higher average conversion in the catalyst bed of higher internal diffusion resistance at a sufficiently long deactivation time. If PHI(d)>PHI(dcr) = {2(upsilon+1)}1/2, then a non-uniform profile of the fraction of unpoisoned active sites appears in a catalyst pellet, although only concentration-independent deactivation is examined.
