CoMo/Al2O3催化木质素加氢液化工艺的研究

摘要

The catalytic hydrogenation of lignin liquefaction was researched.The results showed the optimum conditions for liquefaction were as follows:reaction temperature 240 ℃ ,the hydrogen pressure over 1 MPa,liquid-solid 100 mL/30 g (ethanol∶ lignin).reaction time 60 min.The lignin liquefaction products were analysized by GC-MS.%对木质素催化加氢液化进行了研究.实验表明,液化的最佳工艺条件为:反应温度240 ℃,氢压1 MPa,溶剂原料比100:30(mL:g),反应时间60 min.用气相-质谱联用仪对液化产物进行了分析.
