1. METHOD FOR CLEANING GASES FROM NITROGEN OXIDES by reducing combustible gases on catalysts in the form of two layers containing oxide, characterized in that, in order to reduce the temperature of gases supplied for purification, and to exclude combustible impurities and carbon monoxide B gases after cleaning , catalysts are used that additionally contain nickel, calcium, barium and titanium oxides. 2. Method POP.1, characterized in that a catalyst is used as the first layer along the gas path with the following content of ingredients, wt%: 20-25 Nickel oxide 0.1-2.0 Calcium oxide 0.4-0 , 8 Barium oxide 0.2-0.7 Dioxide-titanium Else Alkzhini oxide and as the second layer use a catalyst with the following content of i ingredients4 wt.%: 10-15 Nickel oxide (L 0.4-4.0 Calcium oxide 0 , 2-1.5 Barium oxide 0.1-1.5 Titanium dioxide Alumina rest |
