This paper is a preliminary study using cavitation energy to break the carbon and hydrogen in triglycerides of palm oil as a catalystreplacement. The cavities were generated by injecting water via a nozzle into palm oil in the helleshaw cell in volumes of 3ml at pressures varying between 2 and 16 MPa. Glycerol amounts were measured employing a colorimetric andacrolein test method. The result shows that the amount of glycerol formed was greatly influenced by 3 factors, namely, bubble diameters, jet speed and size at 0.002 seconds shortly before the jet reach its maximum speed. The smaller the bubble diameters and the greater the jet flow speed and size at 0.002 seconds, the greater the amount of glycerol produced. © Research India Publications.
