Abstract

A method for oxidizing elemental mercury contained in flue gas uses a catalytic barrier filter. The method comprises directing the flue gas towards the catalytic barrier filter, passing the flue gas through the catalytic barrier in the presence of an oxidant, and outletting the flue gas from the catalytic barrier filter, wherein about fifty percent to about ninety-nine percent of the elemental mercury is oxidized.
