Beschreibung
Zusammenfassung:	The invention relates to a catalytic composition comprising a catalytically active metal and a solid support, in which said catalytically active is rhodium and said solid support is CeO 2. According to the invention, the catalytic composition also comprises an iron compound or a combination of metal compounds, selected from: a) iron, zirconium and, optionally, a lanthanide; b) iron, vanadium and a lanthanide; and c) iron, vanadium and zirconium. The invention also relates to a method for the production thereof and to the use of same for the selective conversion of synthesis gas into ethanol. La presente invención describe una composición catalítica que comprende un metal catalíticamente activo y un soporte sólido, donde dicho metal catalíticamente activo es rodioy dicho soporte sólido es CeO 2, y donde dicha composición catalítica comprende además un compuesto de hierro o una combinación de compuestos metálicos seleccionada entre: a) hierro, zirconio y, opcionalmente, un lántanido; y b) hierro, vanadio y un lantánido; c) hierro, vanadio y zirconio, un procedimiento para su preparación, así como su uso para la conversión selectiva de gas de síntesis en etanol. La présente invention concerne une composition catalytique qui comprend un métal actif sur le plan catalytique et un support solide, ledit métal actif sur le plan catalytique étant le rhodium, ledit support solide étant CeO 2, et ladite composition catalytique comprenant en outre un composé de fer ou une combinaison de composés métalliques choisie parmi a) le fer, le zirconium, et facultativement, un lanthanide ; b) le fer, le vanadium et un lanthanide ; c) le fer, le vanadium et le zirconium. Ladite invention concerne aussi un procédé de préparation de ladite composition, ainsi que l'utilisation de celle-ci pour la conversion sélective de gaz de synthèse en éthanol.
