While operating under cycling conditions it was found that SCR kinetic rate forms from literature are inadequate due to their inability to capture the non-linear relationship between NOx conversion and the amount of stored NH3 on the catalyst.  An experimental technique highlights this non-linear effect, which yields new global approximations.
