摘要
研究秸秆在苯酚中[Hmim]HSO4酸性离子液体的催化液化,使用离子液体为催化剂,苯酚为溶剂,将秸秆直接液化,考察原料配比、反应时间、反应温度以及催化剂用量对秸秆直接液化的实验产率和残渣率影响。得到的最佳工艺条件是:苯酚和稻草粉末的配比10:1,温度150℃,时间1h,催化剂用量0.5g,在这样的反应条件下得到的产率不低于84.57%。
The efficient direct liquefaction of straw was achieved by using ionic liquid [Hmim]HSO4 as catalyst in phenol. The ratio of reactants, reaction time, reaction temperature and quantity of catalyst were investigated. The optimal reaction conditions are： ratio of phenol and straw powder is 10：1, the reaction is kept for 1 h at 150℃, and quantity of catalyst is 0.5 g. Under these conditions, the yield of reaction was more than 84.57%.
