Title (EN) CATALYST FOR THE SYNTHESIS OF AMMONIA
(FR) CATALYSEUR POUR LA SYNTHESE DE L'AMMONIAC
Abstract: front page image
(EN)The invention relates to a catalyst for the synthesis of ammonia from hydrogen and nitrogen, comprising iron oxides and promoters of Al, K, Ca and Mg oxides and where said catalyst in addition comprises a promoter of Ti02 in the amount of 0.3 - 2.5 weight % and a promoter of Zr02. The content of Zr02 is 0.05 - 2 weight %, preferably 0.05 - 1.0 weight %. The catalyst may also comprise a promoter of Ce02, which partly replaces Zr02.
(FR)L'invention porte sur un catalyseur destiné à la synthèse de l'ammoniac à partir de l'hydrogène et de l'azote. Ce catalyseur comprend des oxydes de fer et des promoteurs des oxydes d'Al, K, Ca Mg et, en plus, un promoteur de TiO2 dans une quantité comprise entre 0,3 et 2,5 % en poids et un promoteur de ZrO2. La teneur en ZrO2 est comprise entre 0,05 et 2 % en poids, de préférence entre 0,05 et 1,0 % en poids. Le catalyseur peut également comprendre un promoteur de CeO2 qui remplace partiellement ZrO2.
