RASIO INPUT ENERGI DAN VOLUME REAKTAN PADA PENERAPAN ULTRASONIK UNTUK PENGOLAHAN BIODIESEL
Abstract: The application of
ultrasonic on biodiesel processing can increase the reaction rate and improve
theconversion of plant oils into biodiesel. Factors affecting the rate of
reaction on the application of ultrasonicwaves for biodiesel processing are
temperature increasing, acoustic mixing, onset of cavitations andsurface
tension on the micro bubble, and the formation of hot spots in the form of
instantaneous pressureand high temperature on the molecular scale. The vibrator
dipped into the reactants transferred mechanicalenergy which was transformed
into heat, cavitations and hot spots. This research was conducted to seethe
effect of the volume ratio of reactants and input energy on the rate of conversion
of triglycerides intobiodiesel. The results of this study demonstrated a
significant effect of the energy input to the conversion oftriglycerides into
biodiesel. The greater specific input energy produced the higher conversion and
the higherreaction rate. Input energy by using ultrasonic was significantly
lower than the use of a mechanical stirrer.
