Chelated Iron-Based Nutrient Catalyst Solution
The iron-based nutrient solution functions as a catalyst for wet oxidation of hydrogen sulfide removal, characterized of directly converting H2S into elemental sulfur.
Simple process, adjustable sulfur capacity, large flexibility
Environmental friendly, non-toxicity
Regenerable, no waste disposal problem
H2S, COS removal, by-product elemental sulfur
Adsorption: H2S + 2Fe3+ = 2H+ + S + 2Fe2+
Regeneration: 1/2 O2 + H2O + 2Fe2+ = 2OH- + 2Fe3+
