Reduction of Manganese Ores by Methane

reduction process Therefore, optimum methane content in the CH4-H2-Ar gas for the MnO reduction is 10-15 vol Effect of hydrogen concentration on manganese oxide reduction was quite marginal, however increase in hydrogen content decreased carbon deposition Addition of CO to the reducing gas retarded manganese oxide reduction...

The reduction and oxidation behaviour of manganese oxides ,

The reduction of manganese oxides with methane was studied to investigate the suitability of manganese as an oxygen storage compound Manganese oxides are reduced by CH 4 to a lower-valent manganese oxide, producing CO 2 and water Once the manganese oxide is reduced, it can be regenerated, ie reoxidised...
