Effect of enhanced support acidity on the sulfate storage and the activity of Pt/γ-[Al.sub.2][O.sub.3] for NO oxidation and propylene oxidation

NO oxidation and propylene oxidation were studied on standard and acidity-enhanced Pt/[Al.sub.2][O.sub.3] catalyst. Deactivation by platinum oxide formation was suppressed by the presence of chlorine and sulfates. After a long S[O.sub.2] exposure, the activity of modified catalysts was higher than t...
