Abstract: The behavior of one- and two-bed systems consisting of Pt–Rh gauze pack (the first bed) and monolith honeycomb catalyst (the second bed) in the conditions corresponding to those in the industrial medium pressure plant for NH3 oxidation to NOx was experimentally studied. At complete NH3 conversion in the gauze pack installation of the monolith results in the increase of the temperature in the gauzes and NOx yield. One dimensional mathematical model with heat and mass exchange between gas and solid phases and considering the effect of monolith as a heat shield was developed. The effect of monolith was supposed to consist preferentially in increasing the coefficients of heat and mass exchange between gas and solid phases in the gauze pack and determined by “hydrodynamic factor” γ depending on monolith geometry. It results in the shift of temperature front towards the frontal gauze and the reasonable increase of NOx yield.
