Abstract

The effects of free fatty acid (FFA) and moisture contents in palm oil, as well as working volume ratio on the production of biodiesel (fatty acid methyl esters; FAMEs), were investigated using palm oil and a non-catalytic supercritical process. FAME content obtained using anhydrous palm oil was 95.8% during the non-catalytic supercritical process. FAME content produced with 15% moisture content and 15% FFA content was 94.4% and 95.1% respectively, which was similar to that of anhydrous palm oil with no FFA. The non-catalytic supercritical process was not affected by FFA or moisture content in oil. By increasing working volume ratio, reaction temperature decreased from 340 °C to 260 °C at the same pressure, whereas FAME content increased from 69.9% to 95.5%.
