Title: Development of a sorbent-based technology for control of mercury in flue gas

This paper presents results of research being, conducted at Argonne National Laboratory on the capture of elemental mercury in simulated flue gases by using dry sorbents. Experimental results from investigation of various sorbents and chemical additives for mercury control are reported. Of the sorbents investigated thus far, an activited-carbon-based sorbent impregnated with about 15% (by weight) of sulfur compound provided the best results. The key parameters affecting mercury control efficiency in a fixed-bed reactor, such as reactor loading, reactor temperature, sorbent size distribution, etc., were also studied, and the results ire presented. In addition to activated-carbon-based sorbents, a non-carbon-based sorbent that uses an inactive substrate treated with active chemicals is being developed. Preliminary, experimental results for mercury removal by this newly developed sorbent are presented.
