Theses
The impact of hydrogen sulfide (H2S) pretreatment on the oxidation activity of powdered 1.5% Pt/γ-AL2O3 catalyst was investigated in this study. Fresh 1.5% Pt/γ-Al2O3 catalyst was aged with different concentrations of H2S in air at 400 °C for 24 hours. Then, the aged and fresh catalysts were tested to determine the oxidation activity with diagnostic gases which contained either 1% propane or 1% carbon monoxide in dry air. The test results indicated that the catalysts were deactivated for carbon monoxide oxidation and promoted for propane oxidation as a function of …
