✦ Synopsis

Ah&r&-The effect of intraparticle forced convection on the effectiveness of a porous catalyst was studied experimentally. Depolymerization of paraldehyde, catalysed by nickel-sulfate supported on cylindrical pellet of porous silica-gel, was measured in a basket-type reactor. The effective reaction rate increased with increasing the intensity of convective fluxes within the porous pellets. The dependence of this enhancement on the PeclCt number and Thiele modulus of the system shows good qualitative agreement with predictions based on idealized models.

## Abstract The problem of simultaneous convection, diffusion and reaction inside a porous catalyst slab is considered. A combination of perturbation and integral mathematical techniques are used to derive approximate analytical solutions for the concentration and temperature profiles, as well as f
