Development and application of wustite-based ammonia synthesis catalysts

摘要

In the 1980s, Zhejiang University of Technology (ZJUT) started developing a new catalyst for ammonia synthesis which in final form comprises multi-promoters wustite-based catalysts with Fe1-xO as precursor. This became the first new iron catalyst for ammonia synthesis commercialized since Fritz Haber's promoted iron catalyst. The catalyst is commercialized in the existing or new low pressure process. In this paper, the basic theory, method, technology and practice of the wustite-based catalyst in industrial production and application are reviewed.
