摘要： In a method and apparatus for removing nitrogen oxides from the exhaust gas of a lean-burn automobile, a CO adsorbent component, which may, for example be made of Pd, Ru or Ir, is contained in an exhaust gas cleaning catalyst which captures NOx when the air-fuel ratio of exhaust gas is higher than theoretical air-fuel ratio, and reduces the captured NOx when the air-fuel ratio of exhaust gad is less than or equal to the theoretical air-fuel ratio. The catalyst, which includes Rh, Pt, and element selected from among the alkaline and alkaline earth metals (Na, Mg, K, Li, Cs, Sr and Ca), and a CO adsorbent material comprising Pd, Ir or Ru, has a CO desorption capacity that reaches at maximum level at a temperature within the range from 200 to 220° C. when its temperature is increased in a He gas flow at the rate of 5 to 10° C./min, after said catalyst is saturated at 100° C. Exhaust gas having an air-fuel ratio higher than theoretical air-fuel and exhaust gas having an air-fuel ratio less than or equal to the theoretical air-fuel ratio are alternately made to flow to the catalyst.

摘要： An apparatus and method of highly efficiently purifying nitrogen oxides are provided. An NOx chemisorption reduction catalyst chemically absorbs NOx under a condition that an exhaust gas of an internal combustion engine is an oxidizing atmosphere and deoxidizes adsorbed NOx under a reducing atmosphere.

摘要： An exhaust gas purifying catalyst is provided for purifying NOx contained in an exhaust gas from an internal combustion engine of a vehicle operated at a high air fuel ratio due to excessive oxygen, using unburnt HC or CO in the exhaust gas as a reducing agent. The catalyst comprises platinum, strontium and a rare earth metal, as active components, each supported on a support of inorganic oxide. The active components of the catalyst include platinum of 0.01-3.7 by wt ratio, strontium of 0.01-55 by wt ratio and a rare earth metal of 0.01-36 wt ratio, per the inorganic oxide of 100 by wt ratio.
