摘要： The present invention provides a catalyst for production of nitric oxide from ammonia and oxygen. The catalyst has the composition A((n+1)−x)BxC(n(1−y))DnyO(3n+1)+d, wherein A is a lanthanide (La, Gd, Nd, Sm) or yttrium, B is an alkaline-earth cation (Ca, Sr or Ba), C is Fe and D is Cr, Mn, Ni, Ce, Ti, Co or Mg, wherein A, B, C and D are selected independent of each other. The catalyst has a high selectivity towards nitric oxide and a low ignition temperature in the reactor. Further the present invention relates to a method for the production of gas comprising nitric oxide by the catalyst of the present invention. The produced gas has a very low content of nitrous oxide.

摘要： The inventors have discovered catalyst ignition promoters comprising one or more activated metals. The catalyst ignition promoters are easily prepared from a number of metal sources, including spent catalysts, are activated quickly and provide effective catalyst ignition independent of the quality of the metals that comprise the catalytic converter. The one or more activated metals comprising the ignition promoter are prepared by contacting them with one or more chemical treatments. The activated metal components are prepared into suitable articles, referred to as ignition strips, that are placed in contact with one or more oxidative coupling catalysts, typically in the form of gauzes. The ignition promoters reduce the activation energy for catalyst ignition (also referred to “light off”), enabling ignition of catalyst gauzes that are new, used, contaminated, damaged and combinations thereof at a relatively low auto-ignition temperatures.

摘要： A method of reducing the content of NOx and N2O in gases using a gaseous reducing agent which is used in the amount required for reduction of the NOx in the presence of one or more iron-laden zeolites which have no pores or channels having a width of greater than or equal to 7 Ångström in the crystal structure and at temperatures of less than 450° C. in the reaction zone is described. In this method, the flow rate of the gas mixture and/or the amount of catalyst is/are selected so that the desired degree of decomposition of N2O is achieved. The method can be used, in particular, in nitric acid production, in power stations and in gas turbines.
