  • Patent number: 9616413
    Abstract: 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.

  • Patent number: 9084987
    Abstract: The invention relates to a process to produce catalysts by powder injection molding and the catalysts thereof, wherein the catalysts are made by preparing a ceramic formulation with temperature controlled rheological properties comprising catalytic components, heating the powder formulation up to at least the fluid state transition temperature, shaping a sample by injecting the fluid powder formulation into an injection mold followed by cooling the injected powder formulation below the fluid state transition temperature, de-binding the shaped sample, and sintering the shaped sample to form a ceramic catalyst. Alternatively the ceramic structure may be formed initially followed by a coating of the ceramic structure by one or more catalytic compounds.

  • Patent number: 8992870
    Abstract: The present invention relates to a catalyst comprising 0.1-10 mol % Co3-xMxO4, where M is Fe or Al and x=0-2, on a cerium oxide support for decomposition of N2O in gases containing NO. The catalyst may also contain 0.01-2 weight % ZrO2. The invention further comprises a method for performing a process comprising formation of N2O. The N2O containing gas is brought in contact with a catalyst comprising 0.1-10 mol % Co3-xMxO4, where M is Fe or Al and x=0-2, on a cerium oxide support, at 250-1000° C. The method may comprise that ammonia is oxidized in presence of an oxidation catalyst and that the thereby formed gas mixture is brought in contact with the catalyst comprising the cobalt component on cerium oxide support at a temperature of 500-1000° C.

  • Publication number: 20140372479
    Abstract: A method for characterizing a musical recording as a set of scalar descriptors, each of which is based on human perception. A group of people listens to a large number of musical recordings and assigns to each one many scalar values, each value describing a characteristic of the music as judged by the human listeners. Typical scalar values include energy level, happiness, danceability, melodicness, tempo, and anger. Each of the pieces of music judged by the listeners is then computationally processed to extract a large number of parameters which characterize the electronic signal within the recording. Algorithms are empirically generated which correlate the extracted parameters with the judgments based on human perception to build a model for each of the scalars of human perception. These models can then be applied to other music which has not been judged by the group of listeners to give to each piece of music a set of scalar values based on human perception.
