Synthesis of biodiesel from waste cooking oil via transesterification
Session
Pharmaceutical and Natural Sciences
Description
Biodiesel is an alternative fuel made from byproducts of the meat and vegetable industries, such as soybean oil and chicken fat. Alternately referred to as fatty acid methyl ester, biodiesel can also be made from algae and similar organic materials. During the production stages, the oils or fats undergo a transesterication process where the ingredients are purified, but not stripped of oxygen. The aim of this paper is that instead of dispose fried oil in environment, we collect, process and convert it into biodiesel that has many benefits such as: less toxic, emits less greenhouse gases. So it brings economic and ecological benefits to the environment.
We have been able to synthesize biodiesel through transesterification reaction. First we made the titration of the oil with KOH 0.1% to know how much base we should use. After doing the calculations, we used waste cooking oil, methanol and NaOH. The oil was heated to 70°C, we add sodium methoxide and stirred for 45 minutes. After stirring, we let to sit in separate funnel for 24 hours. After 24 hours we saw two layers, which bottom layer was crude glycerol and upper layer was biodiesel. We’ve rinsed it with water twice until all the impurities are clear out and added magnezium sulphate to absorbs the water.
Results obtained showed that the waste cooking oil have viscosity, free fatty acid, acid value, flash point, cloud point, density, boiling point, biodiesel reaction efficiency, no amount of water and IR spectra.
