DIFFUSION, CONVECTION AND REACTION IN CATALYST PARTICLES - ANALOGY BETWEEN SLAB AND CYLINDER GEOMETRIES

Forced intraparticle convection in a finite cylinder porous catalyst p article is studied. An analytical solution for steady state, simultane ous diffusion, convection and reaction is obtained and the effect of i ntraparticle convection on the catalyst performance, i.e. its effectiv eness factor, is analysed. The relationship for the augmented intrapar ticle 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.
