High Active Fe -Mn Catalyst for Ammonia Synthesis at Low Temperature
- 化学化工－已发表论文 
The catalytic activity of the industrial catalyst A 110 3 after modification with Mn 2+ was found to be increased to about 17.4%. The ammonia synthesis was carried out under conditions of 2 1 MPa, 14400 h -1 and 300 ℃. The increase in activity is explained in terms of the weakness of Fe NN or Fe—N bond based on the XPS and TPD MS results.
