Abstract
NO oxidation and propylene oxidation were studied on standard and acidityenhanced Pt/Al2O3 catalyst Deactivation by platinum oxide formation was suppressed by the presence of chlorine and sulfates After a long SO2 exposure the activity of modified catalysts was higher than the standard catalyst The aged chlorinated sample showed the best propylene oxidation activity while the sulfated one exhibited the best NO conversionThe funding from the Swedish Foundation for Strategic Research F060006 and Swedish Energy agency is acknowledged This work was carried out at the Competence Centre for Catalysis Chalmers University of Technology KCK is financially supported by Chalmers University of Technology the Swedish Energy Agency and the member companies AB Volvo Volvo Car Corporation Scania CV AB Haldor Topsoe A/S and ECAPS AB
