Abstract The increase in demand for energy has caused a clear contradiction between the supply and consumption of these resources, which has triggered countries to divert their attention towards biodiesel. Biodiesel yield and sustainability of the biodiesel production process are highly influenced by the catalyst. Homogeneous catalyst is the conventional method to produce biodiesel, but it requires larger water consumption to purify the final product while on the contrary heterogeneous catalyst does not require expensive utility separation cost and it can be separated from simple filtration method. Thus, this paper comprehensively reviews the conventional and advanced biodiesel reactor technologies, particularly link to the kinetic studies of different types of catalysts. The effects of the operating conditions on the reactor technology with different catalysts are discussed to observe a better oil conversion. Merits and limitations of different catalysts for biodiesel production are then compared. The kinetic studies are reviewed to compare the rate of reaction and activation energy between various types of catalysts. As the catalyst and reactor type selection affect the transesterification reaction, it is necessary to search for the correct combination of catalyst and reactor to increase the efficiency of biodiesel production at a lower cost.

反应器技术和动力学研究对生物柴油应用的影响综述

摘要 能源需求的增加导致这些资源的供需矛盾明显，引发各国将注意力转向生物柴油。生物柴油产量和生物柴油生产过程的可持续性受催化剂的影响很大。均相催化剂是生产生物柴油的常规方法，但它需要较大的水消耗来净化最终产品，相反，多相催化剂不需要昂贵的效用分离成本，可以通过简单的过滤方法分离。因此，本文全面回顾了传统和先进的生物柴油反应器技术，特别是与不同类型催化剂的动力学研究的联系。讨论了操作条件对使用不同催化剂的反应器技术的影响，以观察更好的油转化率。然后比较了用于生物柴油生产的不同催化剂的优点和局限性。回顾了动力学研究，以比较不同类型催化剂之间的反应速率和活化能。由于催化剂和反应器类型的选择会影响酯交换反应，因此有必要寻找催化剂和反应器的正确组合，以更低的成本提高生物柴油的生产效率。
