Biodiesel is a renewable fuel which can be produced through an esterification reaction. The cost of feedstock which resulted in that of biodiesel is a large problem to be resolved. Dark oil from industrial process can be a better alternative for biodiesel production because of its low price. In spite of this, the study of biodiesel production using the dark oil has not been reported. This study provides technical information and catalytic properties on this system. Among the several catalysts, WO(3)/ZrO(2) catalyst was the most effective catalyst in the esterification of the dark oil to fatty acid methyl esters (FAMEs). The catalytic reaction parameters were optimized that 20 wt.% WO(3)/ZrO(2) has a high FFA conversion of 96% at 150 degrees C, 0.4 g/ml (oil), 1:9 (oil to alcohol, molar ratio) and 2h reaction time. The physical and chemical properties of the catalyst were characterized by XRD, Raman spectrometer, BET and NH(3)-TPD.
生物柴油是一种可再生燃料，可以通过酯化反应生产。生物柴油的原料成本是一个亟待解决的大问题。由于价格低廉，工业过程中的黑油可以作为生物柴油生产的更好选择。尽管如此，使用黑油生产生物柴油的研究尚未见报道。本研究提供了该体系的技术信息和催化性能。在几种催化剂中，WO(3)/ZrO(2)催化剂是将黑油酯化生成脂肪酸甲酯（FAMEs）最有效的催化剂。对催化反应参数进行了优化，在 150°C、0.4 g/ml（油）、1:9（油对醇，摩尔比）和 2h 反应时间下，20wt.%WO(3)/ZrO(2)的转化率最高，可达 96%。通过 XRD、拉曼光谱仪、BET 和 NH(3)-TPD 对催化剂的物理化学性质进行了表征。
