ABSTRACT:
In CO-air filters the poisonous carbon monoxide contained in the air to be breathed is brought into reaction with atmospheric oxygen on the surface of a CO catalyst and thus removed. The Pt-catalyst used to date as air filter material offers diminished protection when humidity levels in the air are high. By being subjected to an extra impregnation with vanadium compounds the capacity of the palladium catalyst to catalyze the oxidation of CO under high humidity is increased remarkably. Effectiveness is even increased under dry conditions.
