摘　　要："碳中和"目标提出后,各行各业都在寻求减少碳排放的方法,生物质能源的使用是实现碳中和目标的重要手段之一。生物柴油以其优良的燃烧性能及环保性能成为一种较为理想的生物质燃料,其生产工艺是近年研究热点。连续化生产工艺对生物柴油的规模化制备与推广有着重要意义。目前连续化制备生物柴油的反应装置主要有微反应器、固定床反应器、管式反应器、膜反应器。本文综述了近年来国内外采用连续化工艺制备生物柴油的研究进展。这些研究表明,通过优化反应器结构、使用助溶剂、提高催化剂活性等均可提高生物柴油的收率。最后本文还分析了各反应器存在的不足,并提出了相应的建议,对生物柴油连续化生产进行了展望,以期为低成本、低能耗的生物柴油生产提供参考。After the“carbon neutral”goal was put forward,all industries are looking for ways to reduce carbon emissions.The use of biomass energy is one of the important means to achieve the carbon neutral goal.Due to its excellent combustion property and environmental protection performance,biodiesel has become an ideal biomass fuel,its production process has been a research hotspot in recent years.The continuous production process is significant to the large-scale production and promotion of biodiesel,the reaction devices mainly include microchannel reactors,fixed-bed reactors,tubular reactors,and membrane reactors at present.This review summarizes the research progress in the use of continuous processes to prepare biodiesel at home and abroad recently.These studies shows that the yield of biodiesel can be improved by optimizing the structure of the reactor,using a co-solvent,and improving the activity of the catalyst.Also we analysis the shortcomings of each reactor,and put forward corresponding suggestions,then prospects has been made for the continuous production of biodiesel,so as to provide a reference for the production of low-cost and low-energy biodiesel.
