Decrease in Carbonyl Sulfide in the Feed to Claus Converters by Shift Catalysts
Alumina or commercial shift catalysts were used downstream of a Claus burner to shift carbon monoxide to carbon dioxide before it could react to form carbonyl sulfide. The shift catalysts were effective in preventing formation of carbonyl sulfide, thereby decreasing sulfur losses.
