A new approach

named production of aryl oxygen-containing compounds from the catalytic pyrolysis of bagasse lignin (BL) over perovskite oxide

was proposed. A series of LaTi

(LTF-

) samples were prepared by the solid state reaction method. The crystal phase and morphology of LTF-

x

were characterized by XRD and SEM respectively. Catalytic pyrolysis performance of LTF-

x

was performed by TG-DTG and the distribution patterns of gaseous

liquid and solid products from BL was investigated using a fixed-bed micro-reactor. The optimal reaction conditions were determined:the pyrolysis temperature was 600℃

the mass ratio of

the velocity of carrier gas was 100 ml·min

the rest were

esters and carboxylic acid. The total contents of aryl oxygencontaining compounds were from 62% up to more than 72% under the action of the perovskite. Moreover

the LTF-0.2 sample had nice regenerability.
