This work compares two different types of water regeneration methods, continuous washing and intermittent washing, that are applied to catalytically enhanced activated carbon previously loaded with hydrogen sulfide gas. The efficiency of the two regeneration methods was evaluated using Thermo Gravimetric Analysis (TGA), Coulorimetric titration using Karl Fisher reagent and apparent density "as is". The effectiveness of both methods in terms of regenerability, apparent density, and sulphur and organic loading was investigated. Results demonstrated that regeneration of the activated carbon by intermittent washing is more effective than by a continuous washing, as the former was able to remove more sulphur and organic loading from the activated carbon material than the latter, hence retaining its adsorption capacity.
