摘　　要：炭基固体酸是一种具有高催化活性和稳定性的催化剂。当以高酸值废油脂为反应原料制备生物柴油时,炭基固体酸可同时催化脂肪酸与甲醇的酯化反应和甘油三酯与甲醇的酯交换反应。对炭基固体酸的制备、结构及其分别在酯化反应或酯化与酯交换协同反应中的催化性能方面进行了详细阐述。指出了炭基固体酸存在的一些问题,并展望了其催化制备生物柴油今后的研究方向。The carbon-based solid acid is a catalyst with high catalytic activity and stability, h can simultaneously catalyze the esterification of methanol with fatty acid and the transesterification of methanol with triglyceride when the waste oils with high acid value are used as the raw material for the preparation of biodiesel. The preparation, structure and the catalytic performance of the catalysts in the esterification or simultaneous reaction of esterification and transesterification are reviewed. The problems in the research of the carbon-based solid acid and the directions of the carbon-based solid acid to be used to produce biodiesel in the future are also proposed.
