Abstract

The catalytic reduction of N₂O by H₂, NH ₃, CO, propene and n-decane, in the presence of O₂, has been studied on two Fe-zeolite-β (Fe-BEA) catalysts. In the following experimental conditions (GHSV=35000 h^-1, 2000 ppm N₂O, 3% O₂), CO starts to reduce N₂O from 473 K and is the most efficient reductant in the low temperature domain. The absence of strong adsorption and the ability to reduce Fe^III 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 NH ₃ slip, this reductant can be considered as an excellent candidate owing to the harmless of its reduction products.
