Abstract
The effect of convective flow induced by an external pressure gradient on the performance of a biporous pellet has been studied. The effecti veness factor of such a pellet depends on the convective flow paramete r, lambda, the Thiele modulus, and alpha, which characterizes the rati o of macropore to micropore diffusion times. Considerable enhancement in effectiveness due to convection occurs, especially when macropore d iffusion is the controlling step.
