Abstract
A novel technology for biodiesel production from used cooking oil has been studied. It involves ozonolysis and transesterification in the biodiesel synthesis. The effect of temperature and agitation speed were studied in both ozonolysis and transesterification which has been working simultaneously. The ratio mol for used cooking oil and methanol was I : 5. The ozone concentration was 5.8 mol %, the acid catalyst was 4 % w/w. Result from this study showed that the highest methyl esters produced from this study was at the reaction temperature 30% and 400 rpm. Short chain methyl esters were produced from double bond cracking of unsaturated fatty acids whereas long chain methyl esters were produced from transesterification Ozonolysis was dominant at reaction temperature 20°C and 30°C whereas transesterification was dominant at reaction temperature 40°C. Total methyl esters was higher at 400 rpm compare to that at 300 rpm for both operation temperature of 30°C and 40°C.
