Improvement of the Crude Glycerol with Carbonized Rice Husk

Abstract

In this research, we studied the purification and value-added of crude glycerol which was a by-product of the biodiesel production. The purification of glycerol was systematically studied by comparison between using activated carbon (AC) and carbonized rice husk (CRH). From the experimental results, the purity of the glycerol treated with weight ratios between glycerol:AC (5:2), and glycerol: CRH (5:3) was 98.69% and 96.27%, respectively. The clarity of glycerol treated with activated carbon and carbonized rice husk was 95.77% and 92.46%, respectively.
