Effect of the reductant nature on the catalytic removal of N2O on Fe-zeolite-ß catalysts

Résumé

The catalytic reduction of N2O by H2, NH3, CO, propene and n-decane, in the presence of O2, has been studied on two Fe-zeolite-ß (Fe-BEA) catalysts. In the following experimental conditions (GHSV¼35 000 h1, 2000 ppm N2O, 3%O2), CO starts to reduce N2O from 473 K and is the most e?cient reductant in the low temperature domain. The absence of strong adsorption and the ability to reduce FeIII oxo-cations can be put forward to explain this behaviour. At medium temperature range n-decane become very reactive to reduce N2O. Finally, in the absence of NH3 slip, this reductant can be considered as an excellent candidate owing to the harmless of its reduction products.
