WebAbstract. When heterogeneous chemical reactions take place in porous catalysts, mass transport can occur by bulk diffusion, Knudsen diffusion, and convective transport. … WebSince at steady state the problem of simultaneous diffusion and reaction are independent of the particle shape, an equivalent slab geometry is used for the catalyst pellet, with a characteristic length making the surface to volume ratio of the slab equal to that of the original shape of the pellet.
