提出将CH4重整融入载氧体还原反应过程的固定床化学链燃烧新工艺，将Ni基载氧体与Cu?Fe基载氧体混合作为装填载氧体，考察了反应压力对其低温反应活性的影响. 结果表明，固相载氧体转化率和气相CH4转化率均随压力升高而增大，工作温度下限从0.1 MPa下的600℃降至0.9 MPa下的525℃, 900℃下20次循环的压力损失在0.9 MPa下较0.1 MPa下增加快，但载氧体性能未劣化，也未出现明显的积碳和烧结.
A new chemical-looping combustion process based on fixed beds, which was characterised by integrating methane steam reforming into the reduction step, were proposed. A mixture of Ni-based oxygen carrier and Cu?Fe-based oxygen carrier was prepared and its low temperature reduction performance was investigated at different pressures. The results showed that the conversion rates of oxygen carrier and CH4 were both improved with elevating reaction pressure. The lower limit temperature of the operation was lowered from 600℃ at 0.1 MPa to 525℃ at 0.9 MPa. In addition, after 20 cycle at 900℃, the performance of oxygen carrier did not degrade and no carbon deposition and sintering occurred, although the pressure drop in the oxidation step increased faster at 0.9 MPa than that at 0.1 MPa.
