摘要：Chemical-looping combustion(CLC) offers an effective approach for power generation and CO2 capture. In this work, an NiO-ZrO2 oxygen carrier prepared by three methods was subjected to an optimal reaction temperature test, an optimal flow test and a cyclic redox reaction test to explore the most suitable reaction conditions. Through comparative analysis, it is noted that the coprecipitation method is not suitable for the preparation of this NiO-ZrO2 oxygen carrier, while the oxygen carrier prepared by the mechanical mixing method and solution combustion method obtained a higher CH4 conversion rate and CO2 selectivity. In addition, these two oxygen carriers also showed high stability during successive CLC testing. Therefore, both the mechanical mixing method and the solution combustion method can be used to prepare NiO-ZrO2 oxygen carriers.
