采用单因素法,以四氢萘为供氢溶剂,以Fe_2O_3和S为催化剂,在高压釜内,研究了配比、温度、反应时间和初始氢压对兖州煤与木质素共液化反应性的影响.结果表明,在液化中适量添加木质素可提高兖州煤的液化反应性.综合考虑实验条件和经济成本,得到共液化的最佳工艺条件为:兖州煤:木质素(质量比)=9:1,440 ℃,60 min,8 MPa,在此条件下转化率与油产率分别为86.8%与62.9%.

CT Co-liquefaction reactivity (CLR) of Yanzhou coal and lignin was investigated in the batch autoclave with the addition of tetralin as the hydrogen donor solvent and Fe_2O_3+S as the catalyst by using single-factor method. The impact of the ratio of coal to lignin, temperature, reaction time and initial hydrogen pressure on CLR were studied. The results showed that the addition of the appropriate amount of lignin to Yanzhou coal can enhance CLR of Yanzhou coal. According to comprehensive consideration experimental conditions and the economic cost, the optimum conditions is the ratio of Yanzhou reaction time of 60 min. The conversion and oil yield reached 86.8% and 62.9% at this condition.
