摘要
研究在微波辐射下,脂肪酸和甲醇在自制催化剂作用下酯化反应制备生物柴油的工艺.结果表明:最佳工艺条件为微波输出功率160W,微波反应时间为110 min,醇油物质的量比为5∶1,催化剂用量为2.50g(相对于100 g的脂肪酸),在此条件下反应转化率达到97.08%.与水浴加热相比,采用微波辐射加热制备生物柴油的反应速度快、耗能少、转化率高.
The preparation of biodiesel by reacting fatty acid with methanol using the self-made as catalyst under microwave radiation was studied. The experimental results showed that the optimum process conditions were as follows： the microwave output power was 160W, the microwave radiation time was 110 min, the tool ratio of alcohol/oil was 5：1, the amount of catalyst was 2.50 g corresponding to 100 g fatty acid. Under above conditions, the reactive conversion rate was up to 97.08%. Compared with the traditional water heating reaction, this process had some advantages such as quicker reactive speed, lower energy consumption, high conversion ratio and so on.
