| Summary: | The process of ‘nyamplung’ oil in biodiesel manufacturing are by impurity and some
compounds; such as : alkaloid, phosphatide, carotenoid, chlorophyll, and many others which
are usually called gum. There are three steps of biodiesel manufacturing : degumming, preestherification,
and trans-estherification. Degumming process started by the addition of
phosphoric acid 1% wt and wait for 1 x 24 hours. And then, the oil is washed by methanol :
water : hexane until it has brownish color and separated, where the oil will be dissolved in
hexane. While for the pre-estherification process is done by mixing methanol and oil which
has the ratio methanol : oil = 20 : 1 by using pitch HCl 6% wt for about two hours in 60°C.
The separated oil will be used in the step three. In the trans-estherification, it is done by
mixing the oil with methanol and NaCH3O with the ratio of oil : methanol : NaCH3O = 10 :
60 : 2 for about two hours in 60°C. As the result, biodiesel oil has a yellowish color and 45%
of rendemen. |
