| 摘要 |
Reactor membranes advantageously useful in oxidation reactions of hydrocarbons involving oxygen comprise a selective oxidation catalyst on a mixed conducting, oxide ion selective ceramic membrane of the composition (Sr1-xCax)1-yAyMn1-zBzO3-delta, where A is Ba, Pb, Na, K, Y, an element of the lanthanide group or a combination thereof, B is Mg, Al, Ga, In, Sn, an element of the 3d or 4d period or a combination thereof, x is from 0.2 to 0.8, y is from 0 to 0.4, z is from 0 to 0.6, and delta is a number, dependent on x, y and z, that renders the composition charge neutral. |
