The sorption-enhanced steam reforming process was applied to the tar removal to produce high-purity hydrogen. In this study, the reforming catalyst was Ni/Mg-Ca12Al14O33 prepared by solid-state reaction method, and the CO2 sorbent was CaO-Ca12Al14O33 prepared by sol-gel method. The effects of temperature, S/C ratio (the mole ratio of the steam to the carbon in the reaction system) and the WHSV (mass hourly space velocity) on enhancing hydrogen production from tar reforming. The results showed that the addition of the CO2 sorbent can improve the tar reforming efficiency, with the H2 yield and volume fraction increased significantly. Especially, the H2 volume fraction reached over 95%. As the S/C ratio rose and the WHSV declined, the hydrogen production was accelerated, for both of the common steam reforming and the sorption-enhanced reforming. And, for the two processes, when the S/C ratio reached over 12:1 and the WHSV reached below 0.128 h-1, the change of the reforming efficiency was no longer distinct. Compared to the common steam reforming, the best temperature to produce H2 was decreased for the sorption-enhanced reforming, and the H2 yield at 800℃ can reach 87.35%. Compared to thermodynamic results, the H2 yields from the experiment were lower, but the sorption-enhanced reforming can narrow the gap between the experimental and thermodynamic values.
