Interpretive Summary:

Technical Abstract: Increased emphasis on reduction of mercury emissions from coal fired electric power plans have resulted in environmental regulations that may in the future require application of activated carbons as mercury sorbents. The sorbents could be injected into the flue gas stream where is adsorbs the mercury. The sorbent (now containing mercury) would be removed via filtration or other means from the flue gas. Our preliminary work has demonstrated that activated carbon made from agricultural animal waste material can adsorb mercury from air with great efficiency. In experiments, the manure-based activated carbon removed over 95% of elemental mercury from air streams both in its granular and powder forms. A commercial activated carbon product tested in similar experiments did not perform as well as the manure-based product.
