A method for selectively oxygenating methane to carbon monoxide and hydrogen by bringing the reactant gas mixture at a temperature of at least 600°C into contact with a sole catalyst which is either; a) a catalyst of the formula MxM'yOz where: M is at least one element selected from Mg, B, Al, Ln, Ga, Si, Ti, Zr and Hf, Ln is at least one member of lanthanum and the lanthanide series of elements, M' is a d-block transition metal, and each of the ratios x/z and y/z and (x+y)/z is independently from 0.1 to 8; or b) an oxide of a d-block transition metal; or c) a d-block transition metal on a refractory support; or d) a catalyst formed by heating a) or b) under the conditions of the reaction or under non-oxidizing conditions.

Méthode pour l'oxygénation sélective du méthane en monoxyde de carbone et en hydrogène en amenant le mélange de gaz réactif à une température d'au moins 600 degrés C en contact avec un catalyseur unique qui est soit : a) un catalyseur de formule MxM'yOz où : M est au moins un élément choisi parmi Mg, B, Al, Ln, Ga, Si, Ti, Zr et Hf, Ln est au moins un élément comme le lanthane ou un élément de la série des lanthanides, M' est un métal de transition du bloc d, et chacun des rapports x/z et y/z et (x+y)/z est, indépendamment, de 0,1 à 8; ou b) un oxyde de métal de transition du bloc d; ou c) un oxyde de métal de transition du bloc d sur un support réfractaire; ou d) un catalyseur formé en chauffant a) ou b) dans les conditions de la réaction ou dans des conditions non oxydantes.
