中文摘要:以纳米Zn-Mg-Al高温煅烧物为催化剂,高酸值小桐子油为原料,超声波反应器中连续生产生物柴油,并系统研究超声波辐射协同纳米催化剂催化制备生物柴油的最优条件。研究结果表明,超声波协同纳米催化剂催化制备生物柴油的最优条件为:超声波功率210 W、醇油摩尔比4︰1、催化剂为油质量的1.2%、反应温度60℃时生物柴油收率94.3%。在此优化条件下完全可实现小桐子油连续工业化生产生物柴油的需求,精制后的生物柴油完全符合德国生物柴油标准DIN V 51606: 1997,且理化性质稳定,放置1 a后生物柴油的酸值、密度、黏度和化学组成基本不变。

Abstract:Biodiesel was prepared continuously in an ultrasonic tubular reactor with calcined Zn-Mg-Al hydrotalcite as catalyst and Jatropha oil as raw material with high acid value. Assisted with ultrasonic radialization, the optimized conditions for biodiesel production catalyzed by calcined Zn-Mg-Al hydrotalcite were obtained. Experimental results showed that at the optimized conditions, i.e., ultrasonic power 210 W, methanol to Jatropha oil molar ratio 4:1, catalyst concentration 1.2% and reaction temperature 60℃, the yield of biodiesel was 94.3%. On the optimized conditions, biodiesel could be continuously produced with Jatropha oil as raw material, the specification of biodiesel after purification completely met German biodiesel standard DIN V 51606: 1997 and the physicochemical properties were stable. The acid value, density, viscosity and chemical compositions of biodiesel stored for 1 year were invariable.
