Calcined waste starfish was used as a base catalyst for the production of biodiesel from soybean oil for the first time. A batch reactor was used for the transesterification reaction. The thermal characteristics and crystal structures of the waste starfish were investigated by thermo-gravimetric analysis and X-ray diffraction. The biodiesel yield was determined by measuring the content of fatty acid methyl esters (FAME). The calcination temperature appeared to be a very important parameter affecting the catalytic activity. The starfish-derived catalyst calcined at 750 °C or higher exhibited high activity for the transesterification reaction. The FAME content increased with increasing catalyst dose and methanol-over-oil ratio.
首次使用煅烧废弃海星作为基础催化剂，从大豆油中生产生物柴油。采用间歇式反应器进行酯交换反应。通过热重分析和 X 射线衍射研究了废弃海星的热特性和晶体结构。通过测量脂肪酸甲酯（FAME）的含量来确定生物柴油的产率。煅烧温度似乎是影响催化活性的一个非常重要的参数。在 750°C 或更高温度下煅烧的海星衍生催化剂对酯交换反应表现出高活性。随着催化剂用量和甲醇与油的比例的增加，FAME 的含量增加。
