Design of monolith catalysts for power plant nitrogen oxide (No.+-.) emission control

A mathematical model was developed to describe the reduction of NO with NH 3 in simulated power plant stack gases, over the internal surfaces of monolith-shaped catalysts of the vanadia-titania type. The model indicated that up to 50% improvement in the volumetric activity of these catalysts would be possible if they could be prepared with the computed optimum pore structure
