Abstract

La présente invention concerne un catalyseur amélioré à base d'un corps moulé de catalyseur sous forme de comprimé, contenant un mélange contenant du métal, notamment du cuivre, du zinc et de l'aluminium, et de l'aluminate de calcium comme liant, la proportion en poids d'aluminate de calcium étant comprise entre 1,0 % et 30,0 %, pour la synthèse de méthanol à partir de gaz de synthèse. La présente invention concerne en outre la fabrication de ce catalyseur, ainsi que son utilisation pour la synthèse de méthanol à partir de gaz de synthèse.
