介绍了乙醇作为制备地沟油生物柴油原料醇的应用前景,综述了均相催化(碱、酸及酸碱两步催化酯交换反应)及非均相催化(固体酸、固体碱、酶及超临界法)酯交换反应制备地沟油生物柴油的研究进展,并着重分析了各自的优缺点,旨在为后续研究制备地沟油生物柴油提供参考.
The application prospect of ethyl alcohol as raw materials is introduced and homogeneous catalysis (alkali,acid,acid and alkali two-step) and heterogeneous catalysis (solid acid, solid base, enzymatic and supercritical method) as different catalytic process are reviewed, the advantages and disadvantages are emphatically analyzed, so as to prepare for the future study of biodiesel production from waste cooking oil.
