Catalyst systems for the reduction of the oxides of nitrogen

Patent Foster, G F ; Meissner, H E ; Stiles, J L

Devices and processes are disclosed for the treatment of waste gases, particularly automotive exhaust gases, to remove the oxides of nitrogen. Mixed noble metal catalysts consisting essentially of platinum or palladium and at least one other noble metal selected from the group consisting of ruthenium, rhodium, and iridium are employed in combination with layered oxide support coatings to eliminate ammonia formation during the removal process.
NO.sub.x catalyst and method of suppressing sulfate formation in an exhaust purification system

Patent Balmer-Millar, Mari Lou ; Park, Paul W ; Panov, Alexander G

The activity and durability of a zeolite lean-burn NOx catalyst can be increased by loading metal cations on the outer surface of the zeolite. However, the metal loadings can also oxidize sulfur dioxide to cause sulfate formation in the exhaust. The present invention is a method of suppressing sulfate formation in an exhaust purification system including a NO.sub.x catalyst. The NO.sub.x catalyst includes a zeolite loaded with at least one metal. The metal is selected from among an alkali metal, an alkaline earth metal, a lanthanide metal, a noble metal, and a transition metal. In order to suppress sulfate formation,more »« less

Catalytic reduction of nitrous oxide in exhaust streams using alkali metals

Conference Perry, R A ; Miller, J A

Recognizing the need to minimize the release of nitrous oxide to the environment, the authors have modeled a process, developed at Technor, to reduce nitrous oxide in exhaust gas streams. This talk will present the results of modeling the use of NaOH for the reduction of nitrous oxide in exhaust gas streams. The authors will also present experimental results of using alkali metal additives to catalytically reduce nitrous oxide. This model is used to show the viability of using alkali metals in practical exhaust streams. The experimental results were obtained from testing in a down-fired multi-fueled combuster operating using naturalmore »« less
Method of removal of nitrogen oxides

Patent Inaba, H ; Onizuka, S ; Kamino, Y

Nitrogen oxides in an exhaust gas are selectively removable by employing ammonia as a reductant and by employing a catalyst composed of alumina, copper, and at least one of the alkali metals, the alkaline earth metals and the transition metals. Optionally, the catalyst composition may include a slight amount (less than 1 percent by weight) of a precious metal such as rhodium, ruthenium, platinum and palladium. This selective removal of nitrogen oxides is not impaired by the presence of O/sub 2/, H/sub 2/O and SO/sub 2/ in the exhaust gas.
