Dissertations

The effect of sulfur poisoning on the activity of catalysts containing 1.5% platinum supported on γ-Al2O3, TiO2, ZrO2, or SiO2 was investigated in this study. These four catalysts were aged with 100 ppmv H2S in air at 400°C for 24 hours to determine the effect of sulfur poisoning under oxidizing conditions. In separate experiments, 1.5% Pt/γ-Al2O3 catalyst was aged in nitrogen containing 100 ppmv H2S to obtain a frame of reference for non-oxidizing conditions.
