Abstract

Concentrated aqueous hydrogen peroxide or another reactive compound in a liquid carrier is activated by atomization and contact with a suitable catalyst that is concurrently atomized in a carrier liquid. Concentrated hydrogen peroxide and a hydrogen peroxide activation catalyst are atomized into a droplet spray for catalytic activation of the hydrogen peroxide in this invention, useful for treatment of a combustion flue gas containing contaminants such as NOχ and/or Hg.
