Thermal stability evaluation of palm oil as energy transport media

The thermal stability of palm oil as energy transport media in a hydraulic system was studied. The oils were aged by circulating the oil in an open loop hydraulic system at an isothermal condition of 55 °C for 600 h. The thermal behavior and kinetic parameters of fresh and degraded palm oil, with an...
