Abstract

System (10) for removal of targeted pollutants, such as oxides of sulfur, oxides of nitrogen, mercury compounds and ash, from combustion and other industrial process gases and processes utilizing the system. Metal oxides, such as oxides of manganese, are utilized as the primary sorbent in the system for removal or capture of pollutants. The metal oxides are introduced from feeders (20) into reaction zones (30, 38) of the system (10) where they are contacted with a gas (15) from which pollutants are to be removed.
