Zigzag micro-channel reactors have been fabricated and used for continuous alkali-catalyzed biodiesel synthesis. The influences of the main geometric parameters on the performance of the micro-channel reactors were experimentally studied. It has been found that the zigzag micro-channel reactor with smaller channel size and more turns produces smaller droplets which result in higher efficiency of biodiesel synthesis. Compared to conventional stirred reactors, the time for high methyl ester conversion can be shortened significantly with the methyl ester yield of 99.5% at the residence time of only 28 s by using the optimized zigzag micro-channel reactor, which also exhibits less energy consumption for the same amount of biodiesel during biodiesel synthesis. The results indicate that zigzag micro-channel reactors can be designed as compact and mini-fuel processing plant for distributive applications.
已经制备了曲折微通道反应器并将其用于连续碱催化生物柴油合成。通过实验研究了主要几何参数对微通道反应器性能的影响。已发现具有较小通道尺寸和更多匝数的曲折微通道反应器会产生更小的液滴，从而导致生物柴油合成效率更高。与传统搅拌反应器相比，使用优化的曲折微通道反应器，在仅28 s的停留时间下，甲酯产率为99.5%时，实现高甲酯转化率的时间可显著缩短，并且在生物柴油合成过程中，对于相同量的生物柴油，其能耗也更低。结果表明，曲折微通道反应器可设计成紧凑的微型燃料加工厂用于分布式应用。
