Abstract (EN): Forced intraparticle convection in a finite cylinder porous catalyst particle is studied. An analytical solution for steady state, simultaneous diffusion, convection and reaction is obtained and the effect of intraparticle convection on the catalyst performance, i.e. its effectiveness factor, is analysed. The relationship for the augmented intraparticle effective diffusivity and an equivalence ratio between the slab and the finite cylinder characteristic dimensions, valid in the whole range of Thiele modulus, are obtained.
