On the kinetics of catalytic reduction of nitrogen oxide by alkenes in oxidizing atmosphere

  • Paolo CarnitiEmail author

A kinetic model is presented which considers the catalytic reduction of NO to N2 by hydrocarbons in oxidizing atmosphere (NO−HC−O2) as the sum of two simultaneous competitive reactions: the red-ox reaction between NO and hydrocarbon (NO−HC) and the hydrocarbon oxidation (O2−HC). The model is developed for alkenes employed as reductants and noble metal catalysts. The ratio of the kinetic constants of the two reactions can be considered as a selectivity index in evaluating the ability of a catalyst to favor the desired NO reduction with respect to the undesired O2−HC oxidation.
