Abstract
The reduction of nitrogen oxides by propene in the presence of air under net oxidising conditions has been studied for two Cu/alumina catalysts of low (1%) and high (5%) copper loadings in a flow microreactor and by DRIFT. The reaction was studied in the range 473-773K using mixtures of 2.5% NO, 1% C{sub 3}H{sub 6} and 10% O{sub 2} with a balance of nitrogen or helium, using samples which were pretreated in air at 673K and also over samples which had been pre-exposed to SO{sub 2} at 473K. The surface species present under reaction conditions have been identified and the sensitivity of their adsorption sites in the two different loaded catalysts to SO{sub 2} pre-treatment has been investigated. SO{sub 2} adsorption enhanced NO adsorption at 473K in the absence of oxygen and, in reaction, enhanced formation of NCO species leading to increased levels of adsorbed CO as a decomposition product
