  • Fe.sub.1-x O-based catalyst for ammonia synthesis
    Patent number: 5846507
    Abstract: This invention relates to a catalyst for ammonia synthesis. The main phase of the catalyst is a non-stoichiometric ferrous oxide expressed as Fe.sub.1-x O, which is structurally in a Wustite crystal phase form having the rock salt face-centered cubic lattice with lattice paracueter of 0.427-0.433 nm. This catalyst, which has quick reduction rate and high activity, and remarkably lowers the reaction temperature, is especially applicable as an ideal low-temperature, low-pressure ammonia synthesis catalsyt and can be widely used in ammonia synthesis industry.
