Abstract[English]
A catalyst composition for converting ammonia (NH3) into nitrogen (N2) and hydrogen (H2) comprises ruthenium (Ru) and rhodium (Rh) as catalytically active materials. The Ru and Rh are supported on a support material. The composition comprises Rh in a mass ratio of 0.2 to 0.5 of the total mass of Rh and Ru combined, and less than 3 wt% Ru and less than 1.5 wt% Rh based on the mass of the composition.[French]
L'invention concerne une composition de catalyseur pour convertir l'ammoniac (NH3) en azote (N2) et en hydrogène (H2), qui comprend du ruthénium (Ru) et du rhodium (Rh) en tant que matières catalytiquement actives. Le Ru et le Rh sont supportés sur un matériau de support. La composition comprend du Rh dans un rapport massique de 0,2 à 0,5 de la masse totale de Rh et Ru combinés, et moins de 3% en poids de Ru et moins de 1,5% en poids de Rh sur la base de la masse de la composition.
