Study on Preparation of Oxygen Carrier Using Copper Slag as Precursor

open access: yesFrontiers in Energy Research, 2021
Copper slag, an important by-product of the copper smelting process, is mainly composed of 2FeO SiO2, Fe3O4, and SiO2. Due to the sufficient metal oxides, copper slag is regard as a potential oxygen carrier (OC), which can be applied in chemical looping ...
