Review of Hydrogen Production from the Steam-Iron Process by Chemical-Looping Combustion

Chemical looping hydrogen production (CLH) is a promising method for pure hydrogen production, which not only can improve energy conversion efficiency and reduce environmental pollution, but also can separate carbon dioxide. This paper try to review the present chemical looping hydrogen process development on the screening of oxygen carrier particles of gaseous fuel and solid fuel, the design of proper reactors, and the system simulation. The design of solid fuel CLH system and the development of oxygen carriers with high reactivity and abrasion resistance for solid fuel at high temperature and pressure will be future research focuses.
