Abstract:

Research progress in microwave promoted biodiesel synthesis is summarized in terms of homogeneous and heterogeneous catalysis processes. Compared with heterogeneous catalysis process，most studies have focused on homogeneous catalysis. Basic catalysts are used widely than acid catalysts for the faster transesterification reaction rate in homogeneous process，while side reactions are prominent. In heterogeneous process，both basic and acid catalysts have been used，in which activated carbon supported catalysts are frequently used for the advantages of low cost and high performance，but the catalyst lifetime needs to be prolonged.

摘要：

以微波为促进手段进行生物柴油制备近几年受到广泛关注，本文从均相和非均相催化转酯化反应的角度，综述了微波促进生物柴油制备的国内外研究进展。与非均相催化过程相比，均相催化过程的研究更加广泛。均相催化剂的研究多以碱性催化剂为主，其反应速率快，但是副反应多。非均相催化剂的研究中，均有采用固体酸或者固体碱催化剂的报道，其中以活性炭为载体的固体催化剂具有廉价、高效的特点，但是其催化剂寿命需要进一步提高。
