NiO particles with Ca and Mg based additives produced by spray-drying as oxygen carriers for chemical-looping combustion
Magazine article, 2008

Chemical-looping combustion is a two-step combustion process where CO2 is obtained in a separate stream, ready for compression and sequestration. The technique involves two interconnected fluidized bed reactors, with a solid oxygen carrier circulating between them. Results of reactivity experiments with 24 different oxygen carriers, based on NiO with NiAl2O4 and/or MgAl2O4 and produced with spray-drying, are presented. The investigation revealed that oxygen carriers supported by MgAl2O4, or where a small amount of MgO was added, displayed an increased fuel conversion when compared to oxygen carriers of NiO supported by NiAl2O4.
