摘    要:为了探究丙酮与乙酸乙酯对生物油储存特性的影响,将不同质量分数(3%、6%、9%、12%、15%)的丙酮和乙酸乙酯分别加入到生物油中,考察各组生物油理化特性随储存时间的变化。结果表明,添加丙酮和乙酸乙酯降低了生物油的含水率,且乙酸乙酯对生物油水分的降低效果优于丙酮。储存35 d后,15%乙酸乙酯组生物油的含水率为13.41%,比空白组(16.32%)降低了17.8%。加入添加剂后各组生物油的运动黏度均显著下降,与乙酸乙酯相比,丙酮对运动黏度影响较大。随着添加剂添加比例的增加,生物油运动黏度降低。储存35 d后,添加丙酮质量分数为3%、6%、9%、12%、15%的实验组生物油的运动黏度比空白组分别降低了37.20%、57.78%、71.92%、79.79%、84.67%。两种添加剂均能使生物油的pH值略微增大。红外光谱分析和气相色谱质谱联用分析显示,丙酮和乙酸乙酯抑制了生物油的老化反应。

Abstract:Different ratios (3%,6%,9%,12%,15%) of acetone and ethyl acetate were added into crude bio-oil from fast pyrolysis to invest the effects of these two additives on the storage stability of bio-oil.The results show that both acetone and ethyl acetate can reduce the water content of bio-oil,and the ethyl acetate performes better than acetone.Compared to the blank control group,the water content decreases by 17.8%(from 16.32% to 13.41%) at 15% dose of ethyl acetate.The viscosities of bio-oil decrease a lot after adding acetone and ethyl acetate,and acetone shows more obvious effect.With the increasing of additive dose,the viscosity of bio-oil decreases.The viscosity of bio-oil decreases more than that of the control group by 37.20%,57.78%,71.92%,79.79%,84.67% with 3%,6%,9%,12%,15% dose of acetone,respectively.There is no significant difference in pH values among acetone and ethyl acetate addition groups and control group.According to the FT-IR and GC-MS analysis,it indicates that acetone and ethyl acetate inhibit the aging reactions of bio-oil during storage.
Keywords:pyrolysis  bio-oil  acetone  ethyl acetate  stability
