- Weisz-Prater_Criterion abstract "The Weisz-Prater Criterion is a method used to estimate the influence of pore diffusion on reaction rates in heterogeneous catalytic reactions. If the criterion is satisfied, pore diffusion limitations are negligible. The criterion is Where is the reaction rate per volume of catalyst, is the catalyst particle radius, is the reactant concentration at the particle surface, and is the effective diffusivity. Diffusion is usually in the Knudsen regime when average pore radius is less than 100 nm.For a given effectiveness factor,, and reaction order, n, the quantity is defined by the equation:for small values of beta this can be approximated using the binomial theorem:Assuming with a 1st or zero order reaction gives values of , 0.6 and 6 respectively. Therefore for many conditions, if then pore diffusion limitations can be excluded.".
