KATALYSATOR FÜR DIE SYNTHESE VON AMMONIAK AUS BASIS VON FE(1-X)O

摘要

This invention relates to a catalyst for ammonia synthesis. The main phase of the catalyst is a non-stoichiometric ferrous oxide expressed as Fe1-xO, which is structurally in a Wustite crystal phase form having the rock salt face-centred 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.
