This research investigated the production of biodiesel from soybean oil (transesterification process) using pure calcium oxide and calcium oxide obtained from eggshell as heterogeneous catalysts. Uncalcined eggshell and calcined eggshell catalysts produced were analysed using XRF and XRD spectrometers. The processing parameters considered during the transesterification of the soybean were methanol/oil mole ratio, catalyst concentration and reaction time and their effects on biodiesel yield were evaluated. Reaction temperature of 60 °C and stirring rate of 450 rpm (revolution per minute) were kept constant. As a result of calcination, XRF analysis revealed an increase in CaO percentage composition of eggshell catalyst from 96% to 97%. Also, the biodiesel yields obtained revealed similar performance patterns for both the calcined eggshell catalyst and the pure CaO catalyst.
本研究使用纯氧化钙和从蛋壳中获得的氧化钙作为非均相催化剂，对大豆油生产生物柴油（酯交换过程）进行了研究。使用X射线荧光光谱仪（XRF）和X射线衍射仪（XRD）对所制备的未煅烧蛋壳催化剂和煅烧蛋壳催化剂进行了分析。在大豆酯交换过程中考虑的工艺参数为甲醇/油摩尔比、催化剂浓度和反应时间，并评估了它们对生物柴油产率的影响。反应温度保持在60℃，搅拌速率保持在450转/分钟（每分钟转数）。煅烧结果表明，XRF分析显示蛋壳催化剂的CaO百分组成从96%增加到了97%。此外，所获得的生物柴油产率表明，煅烧蛋壳催化剂和纯CaO催化剂具有相似的性能模式。
