Adsorption of SO(sub 2) on sewage sludge-derived materials

Article Abstract:

A dewatered sewage sludge-derived pellet product, and carbonated coconut shells are ground and used to investigate the adsorption of sulfur dioxide from the air. The breakthrough curves for the carbon adsorbents are graphed, as are the thermogravimetric curves for the adsorbents.

Sewage sludge-derived materials as efficient adsorbents for removal of hydrogen sulfide

Article Abstract:

Sewage sludge-derived materials, such as the fertilizer terene, that have been carbonized at 950 degrees Centigrade proved to be efficient absorbents of hydrogen sulfide from moist air. The adsorbents are efficient until the pore entrances are blocked with sulfur resulting from the oxidation reaction.
