A method and composition are described for catalytically converting unburned hydrocarbons and carbon monoxide to carbon dioxide and reducing nitrogen oxides to nitrogen during or subsequent to the combustion of fossil fuels while adsorbing sulfur oxides. The method and composition of the invention are also useful for treating reducing gases containing one or more of hydrogen sulfide, ammonia, and carbonyl sulfide to reduce these gaseous components to non-polluting components such as nitrogen, hydrogen, and water while adsorbing sulfur so that it can be removed from the system. The method and composition of the invention are especially characterized by their use to remove polluting gaseous components from fossil fuels during combustion or subsequent to combustion or from reducing gases and in various stages as long as the catalyst adsorbent system of the invention is brought into contact with the gaseous contaminants being removed.
A method for catalytically converting unburned hydrocarbons and carbon monoxide to carbon dioxide and reducing nitrogen oxides to nitrogen during or subsequent to the combustion of fossil fuels while absorbing sulfur oxides, which comprises contacting gaseous products of said combustion with a catalytic material for catalyzing said conversion and reduction reactions, said catalytic material being physically combined onto an adsorbent matrix selected from the group consisting of calcium aluminate, calcium aluminate cement, barium titanate, and calcium titanate.
A method for treating reducing gases containing one or more gaseous components selected from the group consisting of hydrogen sulfide, ammonia and carbonyl sulfide to reduce said gaseous components to non-polluting components and adsorbed sulfur which comprises contacting said reducing gases with a catalytic material for said conversion which is physically combined onto an adsorbent matrix selected from the group consisting of calcium aluminate, calcium aluminate cements, barium titanate, and calcium titanate.
