Abstract:
In order to study the oxidative stability of biodiesel, the accelerating oxidation process for eight hours was carried out to determine the properties of oxidative oil, such as kinematic viscosity, acid value and peroxide value every two hours, they were compared with the ones of biodiesel/diesel blend fuel. The results show that oxidation stability of biodiesel is inferior to mineral diesel, with the increasing of biodiesel mixed ratio, oxidation stability of blend fuel decreases. The influence of four different antioxidants on oxidative stability were examined, an approximate one was found, it can markedly restrain the oxidation of biodiesel. 2 tabs, 8 figs, 8 refs.
