Abstract

A research program has been designed to address the major mechanisms for speciation and partitioning. Chars generated from three coals (Pittsburgh, Illinois 6 and Wyodak) are used as sorbent material for both elemental mercury and mercuric chloride. The temperature of the source as well as the char sorbent is carefully controlled in the range of 343 to 433 K (70 to 160°C). These chars show consistent higher mercury capture in the case of mercury chloride (over elemental mercury) as the mercury source. Elemental mercury reacts chemically with sulfur in the char. HgCl2 does not appear to be reacting with sulfur in the char. The organic sulfur content of the char is a better predictor of the affinity of the char for elemental mercury, while the char surface area appears to be a better indicator of affinity of the char for mercuric chloride.
