Description
Summary:Oxygen carrier particles with the composition ... were found to readily release gas phase oxygen at 850...C, and were capable to oxidize ... completely and convert wood char rapidly to ... during experiments in a batch fluidized bed reactor. The particles were able to release oxygen corresponding to more than 3% of their mass in less than 40 s. Because of the low price and favourable environmental properties of manganese and iron oxides, this finding could be of great importance for the development of chemical-looping combustion with oxygen uncoupling.
