摘要：

This research aimed to enhance biodiesel stability through catalytic transfer hydrogenation using a biomimetic bimetallic catalyst and glycerol as a hydrogen donor. The effects of catalyst species, intermediate solvent, glycerol feed, and glycerol form on biodiesel stability were investigated. In this study, the examined bimetallic catalysts were Zn-Cr-bicarbonate, Zn-Cr-formate, Zn-Cr-Ni, and Cu-Ni/SiO2. Based on the results, the most excellent catalyst was presented by Cu-Ni/SiO2 catalyst with DMF solvent and 10 wt% glycerol feed. This combination demonstrated a significant reduction in iodine (Delta IV = -4.9 g-I2/100 g) and peroxide values (Delta PV = -5.2 meq-O2/kg) accompanied by an elevation of oxidative stability (Delta OS = 4.3 h). Moreover, the reaction of catalytic transfer hydrogenation using these bimetallic catalysts followed the theoretical mechanism of the simultaneous dehydrogenation-hydrogenation process with two different metals. The promotion of bicarbonate and formate ions on the bimetallic catalyst provided hydrogen transfer assistance in the catalyst. Hence, the continuous improvement of biodiesel properties is expected to promote sustainable implementation of cleaner diesel fuel.
