摘　　要：在高压反应釜中,以ZnC l2为催化剂,研究工艺条件对木质素加氢液化影响,并采用GC-MS技术对产物进行检测。结果表明,最佳工艺条件为:以甲醇为溶剂,催化剂添加量7%,反应温度310℃,固液比1∶5,加氢时间1 h。轻馏分产物GC-MS检测表明,主要有甲苯、苯酚、愈创木酚、苯甲醚,大部分产物为苯酚及其烷基取代物。In the autoclave,with ZnCl2 as the catalyst,conditions of hydrogenation on the liquefaction of lignin were researched,and the products were determined by GC-MS.Results showed the optimum conditions were：methanol as solvent,the amount of catalyst 7%,reaction temperature 310 ℃,solid-liquid ratio 1∶5,time 1 h.GC-MS analysis of light distillate products showed that main products of light distillate were toluene,phenol,guaiacol,anisole,most of the products were phenol and its alkyl substituted.
