Abstract: In the process of preparation of biodiesel，the immiscibility of oil and alcohol leads to low transesterification rate and low production efficiency. In the paper，several process intensification technologies，such as mechanical stirring，co-solvent method，supercritical liquid technology，ultrasonic cavitation technology，hydrodynamic cavitation technology and microwave technology are reviewed and compared. The comparison shows that the hydrodynamic cavitation technology is more simple，safe，efficient，reliable for scale-up and can be operated in continuous process，and has a good prospect in industrial application.

摘要： 在生物柴油生产过程中，由于原料油与醇不互溶，导致生物柴油生产过程中酯交换速率低，影响了生产效率。本文从强化反应过程、提高反应速率方面对以下几种强化手段进行了综述和比较：机械搅拌法、共溶剂法、超临界流体法、超声波法、水力空化法、微波法。指出水力空化设备简单，安全、高效，放大可靠，可连续化生产、工业前景良好。
