Abstract

Biodiesel is an unconventional fuel composed of mono-alkyl esters also achieved essentially from the base catalyzed transesterification reaction of oils or fats. It is utilized clean haven’t require single alteration in the diesel engine and also biodiesel does not contain in consequential amount of sulphur. Consequently, biodiesel is presently the preeminent alternate for petro diesel. Biodiesel was synthesized using one step trasesterification reaction using magnesium oxide over aluminum oxide (MgO/Al2O3) at different ratio 5%, 10% and 15%. Moreoverthe biodiesel were analyzed using 6890N network GC/MS and physicochemical analysis cared out are compared according to international standardvia American Society of Testing Material (ASTMD-6751) the results obtain were: Acid value (0.1, 0.1, 0.2mgKOH/g), Density(0.64, 0.82, 0.71g/cm3) Iodine value (0.70, 0.52, 0.70mgI2/100g), Saponification value (0.10, 0.28, 0.63mgKOH/g), and Water & Sediment level (0.002, 0.002, 0.002) for sample A, B, and C, more ever the percentage yield obtained were (51%, 50%, 50.5%) for A, B, and C.

MgO/Al2O3催化剂催化非洲蛇籽油原位酯交换制备生物柴油

生物柴油是一种非常规燃料，主要由油或脂肪的碱催化酯交换反应合成的单烷基酯。它是清洁利用的，不需要对柴油机进行任何改动，而且生物柴油不含大量的硫。因此，生物柴油目前是石油柴油的最佳替代品。以氧化镁与氧化铝(MgO/Al2O3)的比例分别为5%、10%和15%，采用一步酯反应合成了生物柴油。采用6890N网络GC/MS对生物柴油进行分析，并根据美国材料测试协会(ASTMD-6751)的国际标准对理化分析结果进行比较，得到的结果如下:样品A、B和C的酸值(0.1、0.1、0.2mgKOH/g)、密度(0.64、0.82、0.71g/cm3)、碘值(0.70、0.52、0.70 mgkoh /100g)、皂化值(0.10、0.28、0.63mgKOH/g)、水和沉积物水平(0.002、0.002、0.002)，所得收率分别为A、B和C的51%、50%、50.5%。
