摘要：

A lumped parameter model of monolith SCR reactors is developed which accounts for both inter- and intra-phase transport of reactants, and implements an approximate analytical solution for diffusion and reaction inside the pores of the monolith walls suitable for specific Rideal SCR kinetics. The model is validated by experiment on a purely predictive basis, using ind pendent intrinsic kinetics of the SCR reaction determined over a SCR catalyst ground to very fine particles. Model predictions of NO conversion are successfully compared with data obtained over the same catalyst in the form of monolith. Analyses of the influence of catalyst pore structure and of feed maldistribution are presented.
