Spray-dried NiO-based oxygen carriers developed for chemical looping combustion required high calcination temperatures above 1300 ℃ to obtain high mechanical strength applicable to circulating fluidized-bed process. In this study, the effect of CBB (CaO·BaO·B2O₃) addition, as a binder, on the physical properties and oxygen transfer reactivity of spray-dried NiO-based oxygen carriers was investigated. CBB addition resulted in several positive effects such as reduction of calcination temperature and increase in oxygen transfer capacity and porosity. However, oxygen transfer rate was considerably decreased. This was more apparent when a higher amount of CBB was added and MgO was added together. From the experimental results, it is concluded that CBB added NiO-based oxygen carriers are not suitable for chemical looping combustion and a new method to reduce calcination temperature while maintaining high oxygen transfer rate of NiO-based oxygen carriers should be found out.
