摘要：The effect of reaction time, ratio of solvent/HL and reaction of atmosphere on the liquefaction of HL under supercritical ethanol solution were depicted. It was indicated though analyzing the products yield and distribution and HL conversion and oil yield based on C, that lOmin is preferred for the liquefaction of HL while longer time would intensify the condensation reaction; preferred ratio of solvent/HL was 10:1, HL could not be depolyzed completely under less ratio while the condensation reaction between solvent and intermediate would be intensified under high ratio; the liquefaction results were coincided either under N2 or under H2 atmosphere, which indicated that H2 was not benefit for the liquefaction of HL.
