Abstract

Stäng
- The oxidation of NO and C3H6 over a 1wt% Pt/Al2O3 catalyst was studied. Ageing of the catalyst at 250 °C for 22 h with a gas flow containing 30 ppm SO2 decreased the dispersion and increased the catalytic activity for the two reactions. Two types of sulfur species were formed during ageing, the less stable of which have to be eliminated to recover high activity. The most stable species, probably sulfates stored on the support, affect the conversion during extinction only.
