Abstract

Simultaneous NO reduction and CO oxidation in the presence of O₂, H₂O and SO₂ over Cu/Mg/Al/O (Cu-cat), Ce/Mg/Al/O (Ce-cat) and Cu/Ce/Mg/Al/O (CuCe-cat) were studied. At low temperatures (<340°C), the presence of O₂ or H₂O enhanced the activity of CuCe-cat for NO and CO conversions, but significantly suppressed the activity of Cu-cat and Ce-cat. At high temperature (720 °C), the presence of O₂ or H₂O had no adverse effect on the NO and CO conversions over these catalysts. The addition of SO₂ to NO + CO + O₂ + H₂O system had no effect on the reaction of CO + O₂ over Cu-cat, but deactivated this catalyst for NO + CO and CO + H₂O reactions; over Ce-cat, all of these reactions of NO + CO, CO + O₂ and CO + H₂O were suppressed significantly; over CuCe-cat, NO + CO and CO + O₂ reactions were not affected while the reaction of CO + H₂O was slightly inhibited.
