Characterization Of Mixtures Of Natural Manganese Ore

Characterization Of Mixtures Of Natural Manganese Ore

Abstract Manganese oxides have high activity at temperatures below 200176C and are currently being examined for use as selective catalytic reduction SCR catalysts. Natural manganese ore NMO is inexpensive, composed mainly of MnO2, and can be used as an SCR catalyst. However, the activity of NMO decreases significantly in the presence of moisture, and for this reason it has been difficult to ...
