This paper constitutes a review of the control of toxic metal emissions using sorbents. The objective of sorbent-in-jection methods is to effectively capture the metal species (preferably transform it to an environmentally benign fo rm) and to suppress the fraction in the submicrometer mode. The design of an effective sor-bent-injection methodology thus requires an understanding of the fate of the metallic species and its transformation pathways (transfer to the gas phase, subsequent chemistry at high temperatures, and aerosol formation and growth dynamics) in the combustor. Several different sorbent methodologies used for metals capture are discussed, and a mechanistic description is provided. The need for further experimentation and pilot scale testing is also emphasized.
