木质素加氢液化研究

Research on effect of lignin hydrogenation liquefaction

在高压釜内,研究了温度、反应时间、初始氢压和搅拌速率对木质素加氢液化反应的影响。结果表明,木质素加氢液化的最佳工艺条件为:温度300℃,反应时间60 min,氢压3 MPa,搅拌速率800 r/min。在此条件下,木质素转化率与液体产率分别为71.3%与66.8%。

The influence of stirring speed,temperature,reaction time and initial hydrogen pressure on lignin hydrogenation liquefaction were studied.The results indicated the optimum conditions were the temperature 300 ℃,cool hydrogen pressure 3 MPa,reaction time 60 min and stirring speed 800 r/min.The conversion and liquid yield reached 71.3% and 66.8% under this condition.
