Description:
Objective:The objective of the research conducted by the Center for Air Toxic Metals (CATM) is to address air toxic trace element emissions, which have become a matter of worldwide concern as well as a regulatory issue in the United States. The goal of CATM is to develop key information on air toxic metal compounds to support development and implementation of pollution prevention and control strategies that will reduce air toxic metal emissions and releases to the environment.
This project is intended to develop and test promising mercury control technologies, such as sorbents that will provide rapid in-duct capture of mercury, sorbent regeneration, catalysts to oxidize Hg0 for capture in a wet scrubber, modification of wet scrubbing techniques to enhance mercury capture, or cleaning of the coal before combustion. A further goal is to determine the interaction between flue gas constituents, mercury species, and sorbents. This information has been used to develop and refine a dual functionality model for mercury/flue gas interactions with carbon sorbents. Protocol development for bench- and pilot-scale testing is an ongoing task in this program with a current focus on an entrained flow reactor. To expand our understanding of mercury capture by activated carbon in flue gas, a full factorial matrix of bench-scale fixed-bed tests was completed to determine the effects of the flue gas constituents on the capture of mercuric chloride. Under some conditions, significant reduction of the oxidized mercury to Hg0 occurs across the activated carbon bed.
