To realize the resource and high-value utilization,a new approach,named bagasse lignin (BL) used to produce aryl oxygen-containing compounds by catalytic pyrolysis over perovskite,was proposed.LaTi0.2Fe0.8O3 (LTF) samples prepared by the sol-gel method (SG) and the solid-state reaction method (SS) were characterized.The catalytic action on BL pyrolysis was performed by the test of TG-DTG and the evaluation of the fixed bed micro-reactor,the components and contents of the products were determined.The results show that LTF samples have cubic perovskite phase,LTF prepared by SG (LTF-SG) is porous with larger specific surface area than LTF prepared by SS (LTF-SS).During the pyrolysis of BL,the addition of LTF lowers the pyrolysis temperature and the activation energy,the contents of CO2 and CO in gaseous products reduce by 4.6％-8.0％ and 30.7％-34.3％,respectively,the total content of aryl oxygencontaining compounds (including phenolics,guaiacols,syringols and phenylates) in liquid products increases from 62 wt％ to more than 72 wt％,and LTF-SG shows better catalytic performance.LTF samples have nice phase and catalytic stabilities for BL pyrolysis after five successive redox cycles.
