Research progress of microwave assisted biodiesel production

基于微波的选择性、瞬时性及体积性加热的特点,可以有效提高反应分子的平均能量、分子的碰撞频率,加快反应速率,采用微波辅助催化酯交换反应制备生物柴油近几年得到了国内外学者的广泛关注。将微波能应用于生物柴油制备过程具有显著的优势,与传统加热方式相比,采用微波辐射加热,反应时间明显缩短,产物组成也有所变化。因此主要从酸碱催化剂催化酯交换反应和酯化反应的角度,综述了国内外对微波辅助生物柴油制备的研究进展,并对微波优势及未来发展趋势进行了展望。

Due to the characteristics of selectivity, instantaneity and volumetric heating, microwaves can increase the reaction rate by increasing the average energy of organic reaction molecules and increasing their collision frequency. Microwave assisted preparation of biodiesel through catalytic transesterification has attracted more and more attention from the scholars. The application of microwave in the preparation of biodiesel has significant advantages compared to the traditional heating method the reaction time is obviously shortened and the products compositions are changed as well. This paper reviews the research progress of biodiesel preparation through acidic/ basic catalytic transesterification using microwave heating, and the future trend is also prospected.
