Title
(EN) CATALYST AND PROCESS FOR PREPARING AMMONIA
(FR) CATALYSEUR ET PROCEDE POUR LA PREPARATION D'AMMONIAC
Abstract
(EN)
A catalyst for synthesis of ammonia from N2 and H2, containing a basic zeolite support; Group VIII metal clusters supported on the basic zeolite support; and divalent and alkali metal ions incorporated into the zeolite support, and a process for the production of ammonia using such a catalyst.
(FR)
Cette invention se rapporte à un catalyseur pour la synthèse d'ammoniac à partir de N2 et de H2, qui contient: un support en zéolite basique; des grappes de métaux du groupe VIII maintenues sur le support en zéolite basique; et des ions de métaux alcalins et divalents incorporés dans le support en zéolite; ainsi qu'à un procédé pour produire de l'amoniac au moyen d'un tel catalyseur.
