Abstract

Biodiesel is defines as monoalkyl fatty acid ester has represents a promising alternative to be substituted as an alternative fuel for the use of diesel engines. The catalyst used in this study was sodium hydroxide (NaOH) and reactant methanol to obtain chemical compound called methyl esters which is known as biodiesel. The approach of this research is to enhance the yield of Fatty Acid Methyl Esters, (FAME). By using ultrasound clamp on tubular reactor, immiscible liquids of vegetable oil and methanol is able to emulsify together in a short period of time based on ultrasound clamp as compared to the conventional stirring method which takes longer period of time to emulsify and to achieve the desired yield of FAME. The use of ultrasonic energy will eventually cause the rapid movement of the mixture molecule hence creating cavities where the liquids will breaks down and cavitation bubbles is produced. Based on the previous research by Achrnad, 201 1, the optimum result achieve was 98% conversion of esters by using jatropha oil at 5 minutes. The production of biodiese1 using palm oil on ultrasound clamp on tubular reactor with selected angle of 15", 25", 35" or 45" has been undergone. The obtained results for 1 minute of conversion was 94% ester using Visawit palm vegetable oil, methanol to oil molar ratio 9:1, catalyst concentration 0.75 wt.% with the homogenization temperature at 64.5 a C. The produced biodiesel from this technique has been referred according to the ASTM D-675 1 and EN1 42 14.
