摘要：The batchwise liquefaction of Hydrolytic lignin (HL) in supercritical solution in autoclave was depicted. Results indicated that NaOH was an effective catalyst for HL liquefaction, catalyzed by NaOH with preferred temperature 285°C, and which concentration was 0.06 g/mL, material conversion based on C was up to 93.53%, while yield of total oil 94.96%. Results also demonstrated that the addition of Na2S to catalyst could not promote the activity of the liquefaction of HL. The analysis of products identified that the liquefaction of HL was very complicated which may consist of the deoxidation of intermediate from degradation of HL and the broken-off of branched carbon chain of HL.
