摘要
在超声波条件下,以大豆油为原料,氧化钙为催化剂,利用正交试验研究了催化剂用量、油醇比、反应时间和反应温度等对生物柴油产率的影响。由实验得最佳工艺条件为:油醇比(质量)为0.9∶1,反应时间为30 min,反应温度为45℃,催化剂用量为0.9%(占原料油用量的质量分数)。在该条件下制备的生物柴油收率可达96%,其凝点为-2.2℃,闪点为112℃,运动粘度为3.93 mm/s,其性能与0号石化柴油比较接近。
Under the condition of ultrasonic, taking soybean oil as raw material and calcium oxide as catalyst, the influence of catalyst amount, mass ratio of oil to alcohol, reaction time and reaction temperature on the yield of biodiesel was studied. The experiment results show that the optimal conditions are as follows： mass ratio of oil to ethanol is 0.9 ： 1, the reaction time is 30 min, the reaction temperature is 45 ℃, and the catalyst amount is 0.9%; Under the optimal conditions the yield of biodiesel is up to 96%, and the condensation, flash point and kinematic viscosity of the prepared biodiesel are -2.2℃, 112℃ and 3.93 ram/s, respectively, which show that properties of prepared biodiesel are close to No. 0 fossil diesel.
