摘要:
Hydrogen can be produced from a mixture of CH4 and CO2, based on chemical looping techniques. A physical mixture of a Ni/Al2O3 catalyst and Fe2O3–CeZrO2 as oxygen storage material is used in the chemical looping. During the reduction step, CH4/CO2 is converted over Ni/Al2O3 into syngas, which then reduces iron oxide, giving CO2 and H2O. During re-oxidation of the oxygen storage material by steam, H2 with ppm levels of COx is produced.
