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)=X1ln(υ1ρ1)+X2lnυ2ρ2)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+0.00187X2-1.3875×10-5X3FP=57.2638+0.6836X-0.01762X2+1.8983×10-4X3。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: With Xanthoceras sorbifolia Bunge oil from Gansu province as raw materials,biodiesel was prepared and blended with the 0# diesel fuels at 0,5%,20%,40%,60%,80% and 100% on a volume basis.The key properties of blends,such as density,kinematic viscosity,cold filter plug point and flash point were measured.Additionally,the influence of volume fraction of biodiesel on the blends properties was discussed.The density of blends was linear with the volume fraction of biodiesel and its value increased with the increasing of volume fraction of biodiesel.A mixing equation 100ln100ln (υρ)=X1ln (υ1ρ1)+X2ln(υ2ρ2) was used to predict the kinematic viscosities of the blends.For all blends,it was found that there was an excellent agreement between the measured and estimated values of the kinematic viscosities with the relative absolute error less than 1%.An empirical equation CFPP=0.7344-0.1058X+0.00187X2-1.3875×10-5X3 could be used to correlate the cold filter plugging point (CFPP) and the volume fraction of biodiesel (X).The experimental data of flash point (FP) was also correlated as a function of biodiesel volume fraction(X) by empirical third-degree equation,which was given by FP=57.2638+0.6836X-0.01762X2+1.8983×10-4X3.According to the results,the density,kinematic viscosities and flash point of the blends increased with the increase of volume fraction of biodiesel in the blends,whereas the CFPP of blends decreased.The physicochemical properties of blends were improved when mixing 0# diesel fuels with biodiesel,in the purpose of storage,utilization and transportation.

Key words: Xanthoceras sorblfolia Bunge oil, biodiesel, 0# diesel, blends, physicochemical property, mixing rules
