催化转移加氢（CTH）是一种新型的选择性加氢替代工艺，微波加热是有机反应的一种有效加热方法。本研究以Raney-Ni为催化剂，水为溶剂，采用微波加热的方法对麻疯油生物柴油进行CTH。详细分析了操作参数对升级生物柴油组成的影响，得到了麻风油生物柴油CTH的最佳工艺条件。在最佳条件下，反应时间为50 min，亚油酸甲酯的质量转化率为91.98 wt%。在50 min下得到的升级生物柴油，亚油酸甲酯含量为2.45 wt%，油酸甲酯含量为76.70 wt%，硬脂酸甲酯含量为8.45 wt%，碘值为70.21。采用准一级动力学模型对微波加热下麻风油生物柴油CTH的实验数据进行了较好的描述，得到了CTH的动力学速率常数和选择性。考虑到高选择性和高反应速率，以微波能量为热源，Raney-Ni为催化剂，水为溶剂的CTH是催化升级麻风油生物柴油的有效途径。
The catalytic transfer hydrogenation (CTH) is a novel, alternative process for the selective hydrogenation, and the microwave is an effective heating method for organic reaction. In this study, CTH ofJatrophaoil biodiesel was performed through the method of microwave heating using Raney-Ni as catalyst and water as solvent. The effect of operating parameters on the composition of upgraded biodiesel was analyzed in detail, and the optimum conditions for CTH ofJatrophaoil biodiesel were obtained. Under the optimum conditions, the mass conversion ratio of methyl linoleate reached 91.98 wt% at reaction time of 50 min. For the upgraded biodiesel obtained at 50 min, the methyl linoleate content, the methyl oleate content, the methyl stearate content, and the iodine value were 2.45 wt%, 76.70 wt%, 8.45 wt%, and 70.21, respectively. The experimental data of CTH ofJatrophaoil biodiesel under microwave heating were well described by pseudo-first order kinetic model, and the kinetic rate constants and the selectivity of CTH were gained. In view of high selectivity and high reaction rate, CTH using microwave energy as heating source, Raney-Ni as catalyst and water as solvent was found to be an effective approach for the catalytic upgrading ofJatrophaoil biodiesel.
