| dc.description.abstract | Transesterification of palm oil has been conducted in methanol media by KOH
catalyst at reaction temperature and catalyst concentrations. The variation of various
reaction temperature (['1: 3d'C, T2: 500C, T3: 70°C) and the variation of catalytic
concentration (K1= 0,375% w/w, K2 = 0,500% w/w, K3 = 0,625% w/w) in the
transesterification will result in characteristic Biodiesel/ physic of variants of palm oil
(T1K1, T1K2, T1K3, T2K1, T2K2, T2K3, T3K1, T3K2, T3K3). The characteristic that was
tested includes the viscosity, density/ash point, and water content.
Methyl ester which was obtained in every treatment was separated, washed, filtered
and purified by distillation at the temperature of 110°C, which was then
characterized.
The tested Biodiesel in fact, has a linier corretation with the change of reaction
temperature as well as the catalytic concentration except for the flash point
The viscosity has a minimum rate of 2.4571 cSt on a temperature 30 °c and its
catalyst concentration of 0.375% w/w and its maximum 2.5221 cSt on temperature
70 °c still on the catalyst concentration 0.6255% w/w. The density has an maximum
rate of 0.8750 grlcm3 on temperature 70 ° C and minimum rate of 0.8650 grlcm3 on
each catalyst concentration., Noted that flash point is impacted on the reacting
temperature or catalyst concentration as used The water content has an minimum
rate of0.0263% on temperature 70 °c with a catalyst concentration 0.625% w/w and
maximum rate of0.0474% obtained on the reacting temperature 30°C on the catalyst
concentration of 0.375% w/w. | en_US |
