发明名称 CATALYST AND METHOD FOR THE CATALYTIC REDUCTION OF NITROGEN OXIDES
摘要 The invention provides a method for the catalytic decomposition of nitrogen oxides using periodic rich/lean excursions with a high durability even in the presence of oxygen, sulfur oxides and water and at high reaction temperatures. The invention also provides a catalyst for the catalytic decomposition of nitrogen oxides that comprises Rh and/or Pd supported on zirconium oxide, cerium oxide, praseodymium oxide and/or neodymium oxide. The catalyst may also comprise an outside layer of said catalyst type and an inner layer containing Rh, Pd and/or Pt which preferably is supported on an inorganic oxide.
