A catalyst suitable for producing dimethyl ether comprises alumina particles having an average size of 200 µm or less and a methanol synthesis catalyst layer formed around each of the alumina particles. The methanol synthesis catalyst has a weight ratio of 0.05 to 5 to a weight of the alumina particles. The catalyst is produced by forming a layer comprising a methanol synthesis catalyst around each of alumina particles. The dimethyl ether is produced by the method of forming a slurry by introducing the catalyst into a solvent and introducing a mixed gas comprising carbon monoxide and hydrogen into the slurry.

Un catalyseur approprié pour produire de l'éther diméthylique comprend des particules d'alumine de granulométrie moyenne de 200 micromètres ou moins et une couche de catalyseur de synthèse du méthanol formée autour de chacune des particules d'alumine. Le rapport pondéral du catalyseur de synthèse du méthanol aux particules d'alumine est de 0,05 à 5. Le catalyseur est produit en formant une couche comprenant un catalyseur de synthèse du méthanol autour de chacune des particules d'alumine. L'éther diméthylique est produit par la méthode consistant à former une suspension par l'addition du catalyseur dans un solvant et par l'introduction, dans la suspension, d'un gaz mixte comprenant du monoxyde de carbone et de l'hydrogène.
