  • Supported perovskite-type oxides and methods for preparation thereof
    Patent number: 7070752
    Abstract: Supported perovskite-type oxides are described. The perovskite-type oxides have the general formula of AxA?x?ByB?y?O3??, wherein A is an ion of a metal of Group IIIa or IIIb of the periodic table of elements or mixtures thereof; A? is an ion of a metal of Groups Ia or IIa of the periodic table or mixtures thereof; B and B? are ions of a d-block transition metal of the periodic table or mixtures thereof; x, x?, y and y? vary from 0 to 1; 0.95<x+x?<1.05; 0.95<y+y?<1.05; ? is the deviation from ideal oxygen stoichiometry. This invention also provides for the selection of support materials and the shapes of supported perovskite-type oxides as well as the methods for making them.

  • Supported perovskite-type oxides and methods for preparation thereof
    Publication number: 20020179887
    Abstract: Supported perovskite-type oxides are described. The perovskite-type oxides have the general formula of AxA′x′ByB′y′O3-&dgr;, wherein A is an ion of a metal of Group IIIa or IIIb of the periodic table of elements or mixtures thereof; A′ is an ion of a metal of Groups Ia or IIa of the periodic table or mixtures thereof; B and B′ are ions of a d-block transition metal of the periodic table or mixtures thereof; x, x′, y and y′ vary from 0 to 1; 0.95<x+x′<1.05; 0.95<y+y′<1.05; &dgr; is the deviation from ideal oxygen stoichiometry. This invention also provides for the selection of support materials and the shapes of supported perovskite-type oxides as well as the methods for making them.

  • Purification of gases using multi-composite adsorbent
    Patent number: 6358302
    Abstract: The present invention provides for a multi-composite adsorbent mixture which will remove H2O, CO2 and nitrogen oxides and/or hydrocarbons from a feed gas stream. The improvement lies in the use of a third adsorbent which is selective for nitrogen oxides, hydrocarbons or both.
