Abstract
The present invention relates to a solid multicomponent membrane for use in a reactor where the membrane comprises a mixed metal oxide having a structure represented by the formula: La1−xCax(Fe1−y−y′TiyAly′)wO3−4 wherein x, y, y′, w, and d each represent a number such that 0.1≦(y+y′)≦0.8, 0.15≦(x+y′) ≦0.95, 0.05≦(x−y)≦0.3, 0.95<w<1, and d equals a number that renders the compound charge neutral and is not less than zero and not greater than about 0.8. Furthermore, the present invention relates to a use of the membrane in a reactor for generating heat or for generating synthesis gas.
