摘    要:为提高废木屑热解油品质,使其能够作为发动机燃料使用,提出了一条新的热解油提质路线。首先将热解原油进行基于组分分离的乙醚萃取和化学催化相结合的精制过程,得到精制热解油;其次,利用超声反应器制备了精制热解油/柴油新型混合燃料,以单位体积柴油所溶解的精制油的体积定为S值,作为判断乳化效果的准则,考察了不同的影响因素对S值的影响。研究结果表明,乳化剂添加量对S值影响较大,在V精制生物油:V柴油:V乳化剂=10:30:5条件下,存在最佳的乳化超声操作条件:超声时间、超声电功率、乳化温度分别为20 min、540 W、50℃。制备了不同S值的乳化燃料,通过对燃料物理指标的分析发现,该燃料性质稳定、燃烧性能优良,有望成为柴油的替代产品。

关 键 词:精制热解油  乳化  超声作用  萃取

Abstract:A new upgrading method of pyrolysis-oil was proposed to improve the quality of pyrolysis-oil to be an engine fuel. First, the raw pyrolysis-oil was treated by the combination of ether extraction and chemical catalysis. Secondly, the upgrading pyrolysis-oil/diesel blends were prepared by the ultrasonic treatment. The value of S, which is defined as the volume of upgrading pyrolysis-oil dissolved in a unit volume of diesel, was used for evaluating the emulsification of the blends. The results show that the amount of emulsifier plays an important part in the value of S. When the volume ratio of upgrading pyrolysis-oil, diesel and emulsifier equals 10:30:5, the optimal experimental condition is that the ultrasonic time is 20 min, the ultrasonic power is 540 W, the temperature is 50℃. By analyzing the physical characteristics, the blends are found to be stable and have a good combustion performance, which can be a promising alternative to diesel.
Keywords:upgrading pyrolysis-oil  emulsion  ultrasonic  extraction
