Abstract

An overview of the reactivity and reaction mechanism of SO₂ oxidation-sorption and simultaneous reduction of NO by NH₃/O₂ on copper oxide on alumina is presented. This sorbent-catalyst exhibits high activity in SO₂ oxidation-sorption, can be easily regenerated by reductive treatment and shows reasonably good activity in NO conversion to N₂ in the presence of NH₃ and O₂. However, it is shown that an improvment in the rate of the latter reaction may be useful. The possibility of introducing a vanadium oxide component resistant to SO₂ poisoning in order to increase the deNOx rate during the simultaneous sorption of SO₂ is discussed.
