| 英文摘要 | serious char formation caused by the repolymerization of unsaturated decomposition products is a considerable challenge for current lignin utilization. here, a novel and efficient base-catalyzed depolymerization and in situ hydrogenolysis process for lignin decomposition and char elimination was proposed using the synergic catalyst of naoh coordinated with ru/c. in which, lignin was first depolymerized to phenolic monomer and its oligomer, and then the oligomer was further converted to more stable aliphatic alcohols simultaneously. the results showed that more than 92.5% of lignin was converted, giving 12.69% phenolic monomer, 6.12% aliphatic alcohol and less than 14.03% residual solid. this residual solid selectivity was far lower than it from the single catalyst condition. furthermore, the products were analyzed using gc-ms, gpc, hplc-ms and h-1 nmr. the synergistic effect between depolymerization and hydrogenolysis was also investigated through comparative analysis of the feed-stock, products, and the recovered lignin.
