The emission of mercury into the atmosphere from combustion sources has increasingly become a major environmental and health concern. The recent Clean Air Act Amendments have called for close scrutiny and possible limits on mercury emissions. Unfortunately, because it is in the form of a vapor or submicron aerosol in gas streams, elemental mercury has proven very difficult and expensive to control.

A new inexpensive dry sorbent material was recently discovered that exhibits a surprising capability to capture this air-toxic from gases. Initial experiments have shown high preferential sorption of mercury under typical flue gas conditions, as well as potential for the simple recovery of the sorbed mercury. The proposed Phase II work will carry forward the research begun in Phase I. More specifically, it will involve the investigation and optimization of the new sorbents in the laboratory and the demonstration of their use in a pilot panel-bed filter at an existing refuse incineration site.
