Research on Chemical Materials with Characteristic on Chemical Looping Combustion of Co-Doped Fe₂O₃ Oxygen Carrier with CO

Abstract:

Co-doped Fe₂O₃oxygen carriers reacted with CO were investigated in order to study the temperature effect on the redox characterization.Co-Fe₂O₃ were characterized with X-ray diffraction (XRD), BET and transmission electron microscope (TEM), which showed that the surface structure was regular, and the polymorph was stable. The TG (Thermo Gravimetric Analyzer) analysis indicted that, rational doping Co could enhance the reactivity of iron-base oxygen carrier reacted with CO under different conditions. Oxygen carrier with Fe: Co molar ratio of 1:0.1 had best reactivity. With the temperature increased, the reduction degree became deeper and the complete conversion time shortened. The reduction reaction Co_0.1Fe oxygen carrier with CO was carried out step by step, and the entire process was divided into three stages, namely 344.7-391.0, 414.7-472.5 and 607.6-681.5°C.
