PENGARUH ELEKTROLISIS TERHADAP RENDEMEN MINYAK JARAK YANG DIHASILKAN PADA PROSES PEMBUATAN BIODIESEL
Abstract: The use of jatropha
oil as a source of raw material for making biodiesel is needed in order to
decrease the production cost of biodiesel, since jatropha oil is categorized as
non edible fat. In this research, the biodiesel production process by using an
electrochemical reactor has been done. At the beginning of treatment, carried
out the hydrolysis of oil by using HrS04 with acid and oil volume ratio is 1:
20. At follow-up treatment, carried out the decarboxylation via electrolysis.
This process is done by varying the voltage of 0 V, 10 V,20 V,30 V,the
variation of the concentration of 0.5 M acetic acid. 1 M, 1.5 M, as well as the
distance between the electrodes in the reactor 5em and 10 em. From the
experiments shown that electrolysis with voltage parameters, acidic electrolyte solution. and
electrode spacing affects the yield of decarboxylation process. Electrolysis with
1.5 M acetic acid concentration and voltage of 30 volts per cent obtained the
highest biodiesel yield of compound that is 70.432% in the reactor with
inter-electrode distance of 5cm. While in the reactor with inter-electrode
distance of 10 cm. the highest yield was 53.372% by reacting the oil with 1.5 M
acetic acid and voltage 30 Volt.
