CA 2385668

The present invention relates to a solid multicomponent membrane for use in a reactor where the membrane com-prises a mixed metal oxide having a structure represented by the formula: La1-x Ca x(Fe1-y-y'Ti y Al y')w O3-d 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<l, 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.

L'invention concerne une membrane à composants multiples utilisable dans un réacteur. Ladite membrane est constituée d'un oxyde métallique mélangé dont la structure est représentée par la formule: La1-xCax(Fe1-y-y'TiyAly')wO3-d. x, y, y', w et d représentent chacun un nombre tel que 0,1</=(y+y')</=0,8, 0,15</=(x+y')</=0,95, 0,05</=(x-y)</=0,3, 0,95<w<1, et d est égal à un nombre qui neutralise la charge du composé et qui n'est pas inférieur à zéro, ni supérieur à environ 0,8. De plus, l'invention concerne une utilisation de la membrane dans un réacteur pour produire de la chaleur ou un gaz de synthèse.
