摘要：
The BaFe2O4 oxygen carrier and BaFe2O4 oxygen carrier modified by Ni, Ce and K were prepared by the sol-gel method, and the best oxygen carrier was selected as 10%(mass) K modified BaFe2O4 (10K-BF), and the difference was explored. The effect of reaction conditions on its performance was characterized by H2-TPR, XRD, SEM, and BET on the oxygen carrier. The experimental results showed that the addition of Ni, Ce and K all increase the syngas yield. The 10K-BF oxygen carrier exhibited the best performance when the mass ratio of steam to biomass (S/B) was equal to 3, peroxygen coefficient α=0.20 and t=800℃. Its syngas yield was 1.864 m3/(kg Biomass), hydrogen production rate was 1.038 m3/(kg Biomass), carbon conversion rate was 90.49% and carbon deposition rate was 1.33%. After 10 cycles, there was still a high syngas yield and carbon conversion rate. H2-TPR result indicated that the 10K-BF oxygen carrier starts to release oxygen at 300℃ and can participate in the reaction at the initial stage of biomass pyrolysis, which is beneficial to the cracking of tar. XRD characterization showed that the 10K-BF oxygen carrier can recover part of the spinel structure after regeneration. © 2022, Editorial Board of CIESC Journal. All right reserved.
