摘要:
以柴油、复合乳化剂、甲醇与棕榈油为原料,在一定超声反应条件下,采用超声法制备了棕榈油-甲醇-柴油微乳液。结果表明:随着超声功率的提高和超声时间的延长,微乳液的乳化稳定性指数存在最大值;当棕榈油用量超过10份(质量,下同)时,微乳液的稳定性大幅下降,并且CO与氮氧化合物的排放量增大;随着复合乳化剂用量的增加,微乳液的稳定性增强,超过4.0份时,微乳液的稳定性变化趋于稳定;在超声功率为25 W,超声时间为9 min,超声温度为30 ℃,棕榈油、甲醇、柴油和复合乳化剂用量依次为5,5,90,3.0份的最佳超声波反应条件下,以及于发动机负荷为50%,转速为1 200 r/min的应用实验条件下,微乳液的乳化稳定性指数为76.6,CO,NO,NO2的排放量依次为3.0,3.9,1.2 g/(kW·h)。
Abstract:
Palm oil-methanol-diesel microemulsion was prepared by ultrasonic method with diesel, compound emulsifier, methanol and palm oil as raw materials under certain ultrasonic reaction conditions.The results showed that with the increasing ultrasonic power and duration, the emulsifying stability index had a maximum value.When the amount of palm oil exceeded 10 phr (mass, the same below), the stability of the microemulsion had decreased significantly, and the emissions of CO and NOx had increased.With the increasing amount of compound emulsifier, the stability of microemulsion was enhanced, and the stability of microemulsion tended to be stable when it was more than 4.0 phr.Under the optimum conditions of ultrasonic power was 25 W, ultrasonic time was 9 min, ultrasonic temperature was 30 ℃,the amount of palm oil, methanol, diesel and compound emulsifier was 5, 5, 90 and 3.0 phr respectively, and the applied experimental conditions of engine load was 50% ,and the rotate speed was 1 200 r/min, the emulsifying stability index was 76.6, and the emissions of CO, NO and NO2 were 3.0, 3.9, 1.2 g /(kW·h) respectively.
