| 中文摘要: |
| 以小桐子生物柴油为原料，研究了市场上常见的6种抗氧化剂和6种降凝剂复合作用对油样诱导期、凝点、运动黏度和热值的影响规律。结果表明：不同种类降凝剂对抗氧化剂的抗氧化效果影响较大，但影响规律与抗氧化剂种类无关，影响范围在5%以内；降凝剂与抗氧化剂对生物柴油凝点和运动黏度的复合影响较大，主要影响因素是抗氧化剂油溶性，油溶性好的抗氧化剂能够促进生物柴油凝点降低，但相应会增大运动黏度；降凝剂与抗氧化剂对生物柴油热值复合影响较小，影响因素主要是添加剂本身化学成分的热值高低；添加降凝剂可以提高生物柴油热值。 |
| 英文摘要: |
| Using Jatropha biodiesel as raw material, the compound effects of six kinds of antioxidants and six kinds of pour point depressants in market on the induction period, freezing point, kinematic viscosity and calorific value of biodiesel were studied. The results showed that different types of pour point depressants had great effects on the antioxidant effect of antioxidant, but the influence law was not related to the type of antioxidants and the influence range was within 5%. The compound effects of pour point depressants and antioxidants on the freezing point and kinematic viscosity of biodiesel were great. The main influencing factor was antioxidants oil solubility and antioxidants with good oil solubility could decrease the freezing point of biodiesel, but correspondingly increase the kinematic viscosity. Pour point depressants and antioxidants had little effect on calorific value of biodiesel, and the main influencing factor was the calorific value of the chemical components of the additive itself. Adding pour point depressants could increase the calorific value of biodiesel. |
