Abstract

This research aimed to study biodiesel production from refined palm oil stearin and propanol as an alternative fuel. The experimental results found that biodiesel production from refined palm oil stearin using sodium hydroxide as the base catalyst was 74%. Using biodiesel from refined palm oil stearin as an emulsifier in diesel: propanol: biodiesel D90P5B5(RPO), D85P5B10(RPO), and D80P5B15(RPO) at 99.9% propanol purity, the experiments examined the homogeneity and stability of the fuel produced. It was found that D90P5B5(RPO), D85P5B10(RPO), and D80P5B15(RPO) (virtue of propanol 99.9%) were homogeneous. From the results, the physical properties of D90P5B5(RPO) and D90B10(RPO) from the experiment met the high-speed diesel standards except for the flashpoint of diesohol, which was lower than standard high-speed diesel fuel. Furthermore, the results of the lubricating properties test evaluated by High-Frequency Reciprocating Rig (HFRR) according to CEC-F-06-A-96, D90P5B5(RPO) had a wear scar test 236 and D90B10(RPO) had a wear scar test 234, which were related to the better viscosity and lubricity properties than standard high-speed diesel fuel.
