Abstract
The present disclosure relates to ruthenium promoter catalyst compositions. The ruthenium promoter catalyst compositions comprise ruthenium metal species, an oxide support material, and a promoter species independently selected from the group consisting of La, Rb, Y, Yb, K, Cs, and Ba, or hydroxides, nitrates or oxides thereof. The present disclosure also relates to various methods, processes, systems, membranes and/or reactors, which can utilise the ruthenium promoter catalyst compositions, for example in ammonia synthesis.
Claims12
A catalyst composition comprising one or more catalyst hybrid particles and a transport promoter species,
- wherein each catalyst hybrid particle comprises a ruthenium metal species, an oxide support particle having an average particle size from about 5 nm to about 10 μm, and one or more catalytic promoter species each independently selected from the group consisting of La, Rb, Y, Yb, K, Cs, and Ba, or hydroxides, nitrates or oxides thereof, wherein the ruthenium metal species and one or more catalytic promoter species are supported on the oxide support particle,
- wherein the transport promoter species is in the form of a plurality of particles, and
- wherein the transport promoter species comprises a metal species selected from the group consisting of molybdenum, tungsten, iron, cobalt, boron, chromium, tantalum, osmium, palladium, platinum, nickel, and combinations thereof.
