<p>The invention relates to a method for the catalytic reduction of dinitrogen oxide (N2O) in the presence of zeolite with the addition of a reducing agent, characterised in that the reducing agent used is a saturated hydrocarbon such as methane (CH4), propane (C3H8), LPG (C3H8/C4H10) or a combination of these reducing agents. It has been found that temperatures of 400 °C or lower can be achieved for complete N2O conversion even with very low concentrations of the reducing agent and in the presence of water vapour.</p> |
