PENGARUH MASSA MAGNESIUM SILIKAT (MAGNESOL) DAN WAKTU OPERASI PADA PROSES PEMURNIAN BIODIESEL

Biodiesel purification process using a dry cleaning method has been successfully performed. Biodiesel is derived from used cooking oil. Overall purified biodiesel dry washing method to increase the quality. Reaction time and amount used magnesol greatly affect biodiesel purification process. The best conditions obtained at reaction time of 60 minutes and the amount of magnesol 2% w / w. Density, viscosity, flash point, cetane number, free glycerol and total glycerol increased the quality are 3%, 34%, 7%, 22%, 48% and 38%, respectively.
