Some Tips for Biodiesel Fuel Production by Transesterification
For first time transesterification projects, the use of canola, corn, soy rapeseed, and sunflower oil is recommended because they have a low tendency to harden unlike some vegetable oils or animal fats that harden even at room temperature. On the other hand, the use of peanut oil, tallow, or olive oil may require the need to add a neutralizer to provide better performance since these oils have higher acid contents.
If you intend to produce 1,000 liters of biodiesel by transesterification, then measure 1,000 liters of used cooking oil or vegetable oil. Combine with sodium methoxide made by mixing 22 kg of lye and 150 liters of methanol. You can make use of a biodiesel processor to mix the methanol and lye first before adding the heated used cooking/vegetable oil. For this amount of biodiesel production, it would be best to do at least one hour of mixing until the lye is dissolved.
More and more motorists find transesterification, the most common way to make biodiesel, to be quite convenient and simple because the process does not require complicated instructions or hard to find ingredients as additives. Besides, your used cooking oil will finally have a better application instead of being thrown away. The savings on fuel expenses is said to be as much as 50% in the long run!
