Abstract

La presente invenzione riguarda un processo per la riduzione catalitica degli ossidi d'azoto, presenti nei fumi di combustione, che consiste nel porre a contatto questi fumi con una zeolite beta scambiata con sali di cobalto, in presenza di un idrocarburo leggero come riducente.The present invention relates to a process for the catalytic reduction of nitrogen oxides, present in the combustion fumes, which consists in putting these fumes in contact with a beta zeolite exchanged with cobalt salts, in the presence of a light hydrocarbon as a reducing agent.
