INTEGRATED RESERACH ON ADVANCED BIODIESEL SYNTHESIS PROCESS

废食用油中的游离脂肪酸和水阻止了甘油三酯与碱性催化剂的酯交换反应。本研究在气-液-固滴流床反应器中，在甲醇沸点以上的反应温度下，使用CaO颗粒催化剂，实现了高反应速率和易于分离的产物。在微管反应器中采用酸、碱两步法高效合成了生物柴油。

Free fatty acids and water in waste cooking oil prevents a transesterification of triglyceride with an alkaline catalyst. In this study, the high reaction rate and the easy separation of products was realized by using CaO particulate catalyst at the reaction temperature above the boiling point of methanol in a gas-liquid-solid trickle bed reactor. High efficient synthesis of biodiesel was achieved at two-step process with an acid and an alkaline catalyst in microtube reactors.
