Abstract

This work aims at preparing the blended fuels in a stable emulsion in which the biodiesel was obtained from palm oil with applying the near isochoric subcritical trans-esterification. The work procedures are the following: the preparation chemicals needed; the synthesis of the biodiesel; POME (palm oil methyl ester) analysis; the blending process of the aqueous ethanol-biodiesel (Aq.Et-BD) and ethanol-diesel-biodiesel (Aq.Et-BD-D) whereby they formed in a stable emulsion. It was obtained that the compositions of water, ethanol, and biodiesel using ethanol 94-97% were ranged from 0.69-1.60, 10.74-38.40, and 69.57-88.57%. By employing ethanol with concentration 94-95%, the emulsion appeared many droplets distributed throughout the substance. It was observed by increasing biodiesel composition after a stable emulsion attained the phase did not change. After emulsions blended, the work was proceeded with the measurement of the fuel parameters such as density, SG, API, RPV, flash and pour points, cetane number, and distillation properties.
