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 filter in the presence of an oxidant; and outletting the flue gas from the catalytic barrier filter, wherein about 50 percent to about 99 percent of the elemental mercury is oxidized.
