【摘要】：以甘肃产文冠果油为原料,在制备生物柴油的基础上,通过测试文冠果生物柴油与0#柴油混配物(生物柴油体积分数分别为0、5%、20%、40%、60%、80%、100%)的密度、运动黏度、冷滤点、闪点等理化性质,研究了生物柴油体积分数对混配物理化性质的影响规律。结果表明,混配物的密度与混配物中生物柴油的体积分数呈良好的线性关系;混配物的运动黏度可用公式100ln(υρ)=X_1ln(υ_1ρ_1)+X_2ln(υ_2ρ_2)预测,计算值和实测值的相对偏差在±1%之内;混配物的冷滤点(CFPP)、闪点(FP)与生物柴油的体积分数(X)关系分别符合三次多项式CFPP=0.7344 0.1058X+0.00187X~2 1.3875×10~( 5)X~3和FP=57.2638+0.6836X 0.01762X~2+1.8983×10~( 4)X~3。随着生物柴油体积分数的增加,混配物的密度、运动黏度和闪点不断增大,而冷滤点逐渐降低,通过0~#柴油与生物柴油混配,可提高油品在储存、运输和使用过程的理化性能。
[Abstract]:On the basis of the preparation of biodiesel, the density of the mixed ligand of biodiesel and 0# diesel (the volume fraction of biodiesel is 0 5% and 20% respectively) was tested on the basis of the preparation of biodiesel from Gansu Province, and the density of the mixture was 100%. The effects of volume fraction of biodiesel on the physicochemical properties of ligands were studied. The results showed that there was a good linear relationship between the density of the mixed ligands and the volume fraction of biodiesel in the mixed ligands. The kinematic viscosity of the mixed ligand can be predicted by the formula 100ln (v 蟻) = X_1ln (v _ 1 蟻 _ 1) X_2ln (v _ 2 蟻 _ 2), and the relative deviation between the calculated value and the measured value is within 卤1%. The relationship between the cold filtration point (CFPP), flash point (FP) and the volume fraction (X) of biodiesel is consistent with the cubic polynomial CFPP=0.7344 0.1058X 0.00187X~2 1.3875 脳 10 ~ (5) X ~ (3) and FP=57.2638 0.6836X 0.01762X~2 1.8983 脳 10 ~ (4) X ~ (3). With the increase of the volume fraction of biodiesel, the density, motion viscosity and flash point of the ligands increased, while the cold filtration point decreased gradually.
