- The obstacle of biodiesel preparation from waste cooking oil (WCO) is mainly caused by the high content of free fatty acids (FFAs) in the sample. The high concentration of FFAs in biodiesel feedstock often leads to soap formation and difficulty of product separation. In this experiment, WCO was filtrated using a ceramic filter to reduce FFAs before being converted to biodiesel. Ceramic filters were made using natural clay, diatomite, and an iron powder mixture in various compositions. The effect of contact time and ceramic filter composition on flux was investigated. Temperature and flowrate of WCO were set at 40oC and 1.5 L/min, respectively. The results showed that FFAs concentration was decreased from 12% to 0.003% using ceramic filter with the composition of 69% natural clay, 30% diatomite, 1% iron powder, and contact time of 90 minutes. The results also showed that palmitic acid and oleic acid concentration decreased to about 1.5 and 4%, respectively. The results will contribute to the application of ceramic filter as the pretreatment for biodiesel feedstock with high concentrations of FFAs.
