Abstract
Chemical looping combustion,which transfers oxygen from the air to the fuel through an oxygen carrier,avoids the energy-intensive process of oxygen separation,enabling CO2 capture at the source with lower energy consumption.It is regarded as one of the most promising solid fuel-based large-scale carbon emission reduction technologies.This paper provides a systematic review of the research and development progress of chemical looping combustion in China.It introduces the pilot-scale progress,engineering demonstration deployments,and technological roadmaps of chemical looping combustion technology in China.The review covers the current status of fundamental research on chemical looping combustion in China,including oxygen carrier preparation,kinetics and models of oxygen carrier oxidation/reduction reactions,oxygen carrier testing methods,and dual fluidized bed systems.Additionally,future development trends of chemical looping combustion technology are also briefly discussed.
