Non-Catalytic Microwave Assisted Transesterification of Palm Oil with Dimethyl Carbonate

Siti Aqilah Samsuddin

Abstract


A reactor-condenser microwave (600W) was modified as an assisted method for continuous transesterification of palm oil. The high free fatty acid oil was simultaneously neutralized and trans esterified with dimethyl carbonate. With the DMC to oil molar ratio of 10:1, 7:1 and 5:1, with temperature range of 150 degrees to 250 degrees, 2 to 4-hour residence time, the continuous conversion of palm oil to ethyl ester was over 90%. The palm oil biodiesel was analyses using FTIR analysis to determine the conversion yield.  Most ideal ratio was figured out to be 1:7 (oil to DMC) and it continue to next 4 hour of heating to obtain the best result.   The maximum conversion yield achieve was 95.9% and the density, viscosity also fuel properties achieve ASTM standard.
