FIELD: chemistry.
SUBSTANCE: invention relates to catalysts. Described is a catalytic block based on nickel foam and alloys thereof for purifying gases from organic compounds, including benzopyrenes, dioxins, nitrogen oxides, ammonia, carbon and ozone in form of a block which consists of an assembly of separate plates made from nickel foam and alloys thereof with a coating, placed in a cassette made from stainless steel at distance from each other, wherein a support, which is in form of plates made from nickel foam and alloys thereof, which are coated with a heat-resistant coating, is placed at an angle 30-90° to the direction of the gas flow, wherein the support has the following composition, wt %: aluminium oxide 4-55 or titanium oxide - 0.5-10; lanthanum oxide - 0.5-5.0; manganese oxide - 0.25-2.5; silver - 0.1-0.2; nickel foam and alloys thereof - the balance.
EFFECT: wider range of purification catalysts.
