DIFFERENCE IN EFFECTIVE DIFFUSIVITY UNDER REACTIVE AND NON-REACTIVE DIFFUSION CONDITIONS

[摘要] References(12)Cited-By(2)On the basis of a pore model, a difference in average pore radius under reactive and non-reactive diffusion conditions is discussed. This model suggests a difference in intraparticle effective diffusivity value (pore volume diffusivity with no surface diffusion contribution) between these two systems. Experimental pore tortuosity measurements are also reported for commercial catalyst pellets.
