Activated carbons as adsorbents of hydrogen sulfide
We are working on monitoring the performance of activated carbons used to remove hydrogen sulfide odor in the City of New York water pollution control plants. So far mainly carbons impregnated with caustics have been used for this goal. Such carbons are expensive, create a risk of self ignition and require special precaution. That¹s why we are doing the laboratory experiments along with full scale tests to study the possibility of replacement of caustic carbons with virgin ones. Since the surface of activated carbons is very complicated from the point of view its chemistry and porous structure we are trying to define the factors which enhance the adsorption of H2S and its oxidation to water soluble species which may make the regeneration of exhausted carbons using water feasible.
Mechanism of water adsorption on activated carbons
In collaboration with Keith E. Gubbins and Simon McGrother of the Department of Chemical Engineering at the North Carolina State University we are investigating the mechanism of water adsorption on activated carbons. At CCNY we do the detailed characteristics of activated carbons, measure the water adsorption isotherms, and analyze the energetics of the process whereas molecular simulations are done at NCSU. The molecular models used for Monte Carlo simulations incorporate the structural and chemical parameters given by experiments. Doing this we hope to find the improved molecular mechanism by which adsorption occurs.
