If a reaction with mole changes takes place isothermally in a porous catalyst, intrapellet concentration and pressure gradients can develop and mass transfer will occur by simultaneous diffusion and flow. A very useful equation for describing simuItaneous diffusion and flow in porous media is the on
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 r
An analytical study on fully developed forced convection in a homogeneous porous medium is presented. Closed form solutions for the temperature distributions in the transverse direction with the inclusion of frictional heating due to viscous dissipation are obtained, with variations of Darcy number
