The principle of a bubble column reactor for transesterification is similar to reactive distillation,where the reaction products in the gas phase are continuously removed from the reactive zone,while oil,as the reactant,is retained in the reactive zone(liquid phase).酯交换反应所用的流泡罩塔反应器的原理与反应性蒸馏相似，气相反应产物不断从反应区被移除，而作为反应物的油则留在反应区。A dedicated laboratory-scale continuous-floe bubble column reactor,with a predetermined 200ml liquid volume of palm oil in the reactor ,has been used for this study.本实验中采用了一套实验室规模的不断流泡罩塔反应器，预先加入200mL液状棕榈油。In this study,the effects of the methanol feed flow rates(1.5,3.0,and6.0ml/min) and reaction temperatures (250,270,and 290℃) on the biodiesel productivity increased with MeOH feed flow rate and reaction temperature correspondingly.试验结果表明，生物柴油的产率随甲醇供液速度和反应温度增加而相应增加。On the other hand, the purity of the methyl ester in the biodiesel product decreased.另一方面，产物中甲酯的纯度相应下降。 |
