Enhanced selective catalytic wet oxidation of H2S to S ...

Aug 01, 2018· The catalytic wet oxidation of H 2 S was tested in an aqueous solution. The solution was stirred to keep catalyst powders suspension and avoid their settlement. A gas mixture of H 2 S/N 2 /O 2 with constant H 2 S concentration was conducted into the solution at room temperature. Fig. 2 shows that the H 2 S conversion over the yFe/MgO varies as a function of the elapsed time.

Hydrogen Sulfide Monitoring in Wastewater Treatment

Mar 01, 2018· Hydrogen Sulfide (H2S) is a byproduct gas evolved during the treatment of sanitary wastewater. Due to its low odor threshold, in the part- per -billion range, the odor produced by wastewater treatment facilities offends neighboring residents. H2S may be removed from the effluent gas stream by wet, chemical scrubbing.
