ABSTRACT:
Flue gas resulting from combustion of sulfur-containing fuel is treated for reduction of its sulfur dioxide content by creating in it a suspension of finely divided sorbent such as lime, and then contacting it at elevated temperature in a vertical contacting zone with a descending shower of sulfur dioxide oxidation catalyst. The resulting sulfur trioxide is captured as a powdered sulfate.
