Abstract

The research about bleaching Palm Oil Mill Effluent (POME) using active charcoal had
been done. This research is a base research in pretreatment for making POME into
Biodiesel. The higher fat in POME made this oil palm waste has a great potential inreuse
into a renewable fuel. Bleaching is a purification process that been done to breaking
unexpected particulates by using adsorbent. In his research, the bleaching of POME was
done by using active charcoal with the aim is to reduce free fatty acids (FFA) in POME
before use into Biodiesel synthesis. POME sample was heating in 70 oC

andwas degumming with 6% of phosphoric acids than bleaching by 37.5% of active charcoal at
60 oC in 2 hours. Based on the measurement of FFA, FFA of POME that had bleached by
active charcoal has a lower FFA than POME without bleached. So, active charcoal can
reduce POME’s FFA effectively than POME unbleached.
