Abstract：

Chemical looping process for hydrogen generation (CLH) is a new type of hydrogen production with inherent CO₂ separation, high efficiency, high purity, easy segregation and low NO_x emission. Therefore CLH has a broad development prospects. The basic principle of CLH was introduced. The current situation and existing problems were summarized according to the preparation and screening of oxygen carriers, development of reactors system, selection of CLH feeds. In conclusion, 3 key directions in CLH development are pointed out, which are preparation by screening excellent oxygen carriers, design and optimization of reactor, development of CLH system suited for solid fuels.
