摘要：
The reforming of bio-oil to syngas can not only make full use of the components in bio-oil, but also demonstrate the high-value utilization potential of bio-oil into chemicals. NiFe2O4 and Ni based catalysts were coupled to form a catalytic coupling chemical looping reaction system. In order to compare the influence mechanism of catalysts, Ni/Si-NiFe and Ni/VR-NiFe catalytic coupling chemical looping systems were constructed respectively. The pure substances and mixtures of guaiacol, acetic acid and ethanol were used as the models of biomass pyrolysis liquid. The effects of catalyst ratio, reaction temperature, water carbon ratio and reaction time on the product distribution were investigated by steam reforming experiment. Based on the screen of reaction conditions, the stability of the reaction system was further verified by life test, bet and SEM characterization. Finally, the reforming mechanism of the chemical looping coupling catalytic system was analysed through the single component and mixed liquid reforming reaction. The article provided an important theoretical support for biomass thermal conversion to produce chemicals. © 2021, Editorial Board of CIESC Journal. All right reserved.
