本工作的目的是研究原料组成对生物柴油质量的影响，使用酯交换反应。因此，使用甲醇钾作为催化剂和标准反应条件（反应时间，1小时;催化剂的重量，1重量%）将10种精炼植物油转化初始油重量;甲醇/油摩尔比，6/1;反应温度，60 ℃）。根据标准[UNE-EN 14214，2003.汽车燃料。用于柴油发动机的脂肪酸甲酯（FAME）。要求和试验方法]。根据不饱和度和长链饱和因子两个参数，将生物柴油的氧化安定性、十六烷值、碘值和冷滤点等关键参数与甲酯组成进行了关联。最后，建立了基于单不饱和、多不饱和和饱和甲酯组成的三角图，以预测已知其组成的生物柴油的欧洲标准临界参数。(C)2008爱思唯尔有限公司保留所有权利。
The aim of this work was the study of the influence of the raw material composition on biodiesel quality, using a transesterification reaction. Thus, ten refined vegetable oils were transesterificated using potassium methoxide as catalyst and standard reaction conditions (reaction time, 1 h; weight of catalyst, 1 wt.% of initial oil weight; molar ratio methanol/oil, 6/1; reaction temperature, 60 degrees C). Biodiesel quality was tested according to the standard [UNE-EN 14214, 2003. Automotive fuels. Fatty acid methyl esters (FAME) for diesel engines. Requirements and test methods]. Some critical parameters like oxidation stability, cetane number, iodine value and cold filter plugging point were correlated with the methyl ester composition of each biodiesel, according to two parameters: degree of unsaturation and long chain saturated factor. Finally, a triangular graph based on the composition in monounsaturated, polyunsaturated and saturated methyl esters was built in order to predict the critical parameters of European standard for whatever biodiesel, known its composition.
