Trace element emission from coal combustion is a major concern for coal-burning utilities. The study of activated carbon as a multifunctional sorbent for trace metal capture is the focus of this study. In addition to mercury and halides, selenium and arsenic represent two of the most volatile trace species that remain in gas phase in substantial amounts. In this work, fundamental sorption characteristics of the activated carbon for selenium removal from the gas phase are studied. Activated carbons with different structural properties are studied for their usefulness in removing selenium from flue gas. Preliminary sorption studies indicate that selenium removal occurs by physical adsorption, with increased sorption in the presence of moisture in the gas stream.
