Spent Pd catalyst—Component for oxide catalysts, designed for CO oxidation and NO reduction
چکیده انگلیسی

The aim of this investigation is to check the possibility of using, after Pd extraction, the residue of deactivated alumina–palladium catalyst as a component of an oxide composite, as well as to establish the effect of Pd on the catalyst activity. In order to do so, Cu–Co active phase was impregnated on catalyst containing Pd residue (synthesized catalyst 3KN). The polyoxide composition obtained is intended for a catalyst to be used in reduction of NO with CO and oxidation of CO to CO2 in gas mixtures.For comparison Cu–Co oxide catalysts (KA1–KA3) and regenerated Pd catalyst with content of 2% Pd (catalyst KN) were used. It was established that not only the catalyst activity towards NO reduction with CO, but also the resistance to poisoning with SO2 increased in the presence of Pd in combination with the synthesized fresh active Cu–Co phase.In this way the 3KN catalyst is suitable to be used as a catalyst for purification of polluted gases.
