A catalyst system for the reduction of NOcomprises a catalyst comprising a metal oxide catalyst support, a catalytic metal oxide comprising at least one of gallium oxide or silver oxide, and at least one promoting metal selected from the group consisting of silver, cobalt, molybdenum, tungsten, indium, bismuth and mixtures thereof. The catalyst system further comprises a gas stream comprising an organic reductant, and a compound comprising sulfur. A method for reducing NOutilizing the said catalyst system is also provided.

[object Object]

A method comprises injecting a reductant stream comprising a hydrocarbon reductant and water into an exhaust chamber comprising a nitrogen oxide-containing exhaust stream; contacting a composition comprising the reductant stream and exhaust stream with a catalyst; and decreasing a concentration of the nitrogen oxide in the composition comprising the reductant stream and exhaust stream. An exhaust stream treatment system, comprises an exhaust chamber comprising a catalyst; an exhaust stream comprising a nitrogen oxide; and a reductant stream comprising a hydrocarbon reductant and water.

A catalyst system for the reduction of NOx. is provided. The system comprises a catalyst in a first zone comprising a catalyst support, a catalytic metal comprising gallium, and at least one promoting metal selected from the group consisting of silver, gold, vanadium, zinc, tin, bismuth, cobalt, molybdenum, tungsten, indium and mixtures thereof; a catalyst in the second zone comprising a second catalyst support, a second catalytic metal selected from the group consisting of indium, copper, manganese, tungsten, molybdenum, titanium, vanadium, iron, cerium and mixtures thereof The catalyst system further comprises a gas stream comprising an organic reductant. The catalyst system may further comprise a catalyst in a third zone; the catalyst comprising a third catalyst support and a third catalytic metal selected from the group consisting of platinum, palladium, and mixtures thereof. A method for reducing NOx utilizing the catalyst system is also provided.

A catalyst system comprising a catalyst and a reductant is disclosed. The catalyst comprises a metal oxide catalyst support, a catalytic metal oxide, and a promoting metal. The catalytic metal oxide comprises gallium oxide, indium oxide or a combination of the two. The promoting metal comprises at least one of silver, cobalt, vanadium, molybdenum, tungsten, zinc, tin and bismuth. The catalyst comprises about 5 to about 31 mol % catalytic metal oxide and about 0.5 to about 9 mol % promoting metal. The reductant comprises a fluid hydrocarbon having at least 4 carbon atoms. Also disclosed is a process for reducing NOto Nusing the disclosed catalyst system by mixing NOwith a reductant and passing the mixture through a catalyst of the disclosed catalyst system.

A slot armor component for use in a rotor of a dynamo-electric machine comprises a plurality of profile co-extruded polymer layers. The composite cross-section of the profile co-extruded layers may include a first leg portion and a second leg portion disposed at an angle to the first leg portion. The plurality of co-extruded polymer layers may include a glass-filled polymer layer arranged between two unfilled polymer layers such as a glass-filled Ultem layer having a glass-fill concentration equal to or less than 30% arranged between two unfilled Ultem layers or a glass-filled polyetheretherketone (PEEK) layer having a glass-fill concentration equal to or less than 30% arranged between two unfilled PEEK layers.
