METHOD FOR CATALYTIC REDUCTION OF NITROGEN OXIDE EMISSIONS |
摘要 |
The invention concerns a method for trapping NOx in gas treatment to reduce nitrogen oxide emissions. The method is characterised in that it consists in using a mass catalyst based on an oxide of formula (1): AxMn1-yByO2+/- delta wherein: A represents one or several elements selected from groups IA, IIA, IIIA of the periodic table; B is a metal selected among tin and elements of groups IVA to IIIB of the periodic table; x and y having the following values: 0.16 </= x </= 1 and 0 </= y < 0.5, the oxide having a laminar crystallographic or tunnel structure.
