Abstract

Abstract: A systematic research about the liquefaction of alkali lignin in supercritical ethanol using ZSM‐5 zeolite catalysts is reported, which includes the synergistic effect of temperature, catalytic content, and reaction time on product yield and distribution. Fourier transform infrared and gas chromatography‐mass spectrometry analysis were carried out to evaluate the compositions of bio‐oil and solid residue. Under moderate condition, maximum conversion and yield of bio‐oil were satisfactorily high. With the help of ZSM‐5 catalyst, lignin could be successfully converted into aromatic compounds. Abstract : A ZSM‐5 zeolite catalyst combined with supercritical ethanol was applied to produce bio‐oil in alkali lignin catalytic liquefaction. The synergistic effect of relevant reaction parameters on conversion as well as product yields in terms of bio‐oil, solid residue, and aromatic compounds was investigated. ZSM‐5 promoted successfully the conversion of lignin into aromatic compounds.
