Abstract: Chemical-looping combustion（CLC）is a combustion process with inherent CO2 separation，which can simultaneously improve combustion efficiency and reduce environmental pollution. With the concept of CLC，it is advantageous to realize highly efficient utilization of solid fuels with economical feature and low pollution. The present review introduces the technical approaches for solid fuels CLC，and summarizes the recent research advances in reactor deign and oxygen carriers. The existing technical problems in solid fuels CLC are discussed. It is suggested that solid fuels CLC under high temperature and high pressure would be an important tendency for future research.
