Abstract Jatropha curcas biodiesel was taken as the research object, studied the single and compound effects of oxidation degree and temperature on kinematic viscosity of biodiesel, and established a mathematical model. The results indicate that the kinematic viscosity of biodiesel decreases gradually with the increase of temperature, and the mathematical model affected by the single factor of temperature is η = e(A + Bt + Ct2) . The kinematic viscosity of biodiesel increases with the increase of oxidation time. The regression equation between kinematic viscosity and conductivity is established as follows: η = A + Bμ. It is found that the influence of temperature on the kinematic viscosity of biodiesel is much greater than that of oxidation, and the higher the temperature, the lower the influence of oxidation on the kinematic viscosity of biodiesel. Through the analysis of the influence weight of two factors and the change rate of kinematic viscosity, it is found that with the increase of temperature, the effect of conductivity on the change rate of kinematic viscosity of biodiesel is positive, but the influence decreases gradually. The relationship between kinematic viscosity, temperature and oxidation

氧化程度和温度对生物柴油粘度影响的研究

摘要 以麻疯树生物柴油为研究对象,研究了氧化度和温度对生物柴油运动粘度的单一和复合影响,并建立了数学模型。结果表明,生物柴油的运动粘度随着温度的升高而逐渐降低,受温度单因素影响的数学模型为η=e(A+Bt+Ct2)。生物柴油的运动粘度随着氧化时间的增加而增加。建立运动粘度与电导率的回归方程如下: η = A + Bμ。发现温度对生物柴油运动粘度的影响远大于氧化作用,温度越高,氧化对生物柴油运动粘度的影响越小。通过对两个因素的影响权重和运动黏度变化率的分析发现,随着温度的升高,电导率对生物柴油运动黏度变化率的影响为正,但影响逐渐减小。运动粘度、温度和氧化的关系
