Environmentally benign sorbents for removing mercury from flue gas
Abstract
A new class of carbon-based sorbents for vapor-phase mercury removal is disclosed in this invention. The optimum structure of the sorbent particles, and a method to produce the sorbent, are described. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The thin metal-oxide layer acts as a barrier for the adsorption of Air Entrainment Admixture (AEA), the component used to stabilize bubbles in cement), thereby enhancing its concrete friendliness. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.
