Abstract Using Raney-Ni as catalyst, isopropyl alcohol as hydrogen donor and water as solvent, the intensification of catalytic transfer hydrogenation (CTH) of Jatropha oil biodiesel by the microwave at different constant power was studied in detail. The effects of important parameters, including catalyst loading, microwave power, isopropyl alcohol amount, water quantity, and stirring speed, on the CTH of Jatropha oil biodiesel have been investigated. For CTH of Jatropha oil biodiesel, the non-isothermal kinetics at constant microwave power of 50 W and at 75 were gained, and the results of verification showed the rate parameters calculated were credible. Furthermore, the isothermal kinetics at constant microwave power of 100 W and at 150 W were investigated. The results showed the microwave intensity had a significant influence on the reaction rate and the selectivity of CTH of Jatropha oil biodiesel. At the high microwave intensity, the reaction rate was accelerated and the selectivity was increased. It was found that the non-thermal effect from microwave truly played an important role in the strengthening of CTH reaction, and had a higher positive effect on the hydrogenation reaction of methyl linoleate to methyl oleate than on the hydrogenation reaction of methyl oleate to methyl stearate. Moreover, the performance of upgraded Jatropha oil biodiesel has been presented. Overall, the work has provided an approach to investigate the non-isothermal kinetics at constant microwave power, and our finding has clearly demonstrated the intensification from microwave played different influences on the two consecutive steps of CTH reaction for Jatropha oil biodiesel.

恒定微波功率下生物柴油的微波辅助催化转移加氢

摘要 以Raney-Ni为催化剂，异丙醇为供氢体，水为溶剂，详细研究了不同恒功率微波对麻风树油生物柴油催化转移加氢(CTH)的强化作用。研究了催化剂载量、微波功率、异丙醇用量、加水量、搅拌速度等重要参数对麻风树油生物柴油CTH的影响。对于麻风树油生物柴油的CTH，获得了恒定微波功率50 W和75的非等温动力学，验证结果表明计算的速率参数是可信的。此外，研究了 100 W 和 150 W 恒定微波功率下的等温动力学。结果表明，微波强度对麻风树油生物柴油的反应速率和CTH选择性有显着影响。在高微波强度下，反应速率加快，选择性增加。发现微波的非热效应确实对CTH反应的强化起到了重要作用，对亚油酸甲酯加氢反应生成油酸甲酯比对油酸甲酯加氢反应生成硬脂酸甲酯有更高的积极作用。 . 此外，还介绍了升级后的麻风树油生物柴油的性能。总的来说，这项工作提供了一种研究恒定微波功率下的非等温动力学的方法，
