Reduction of high content of free fatty acid in sludge palm oil via acid catalyst for biodiesel production
Published 2011“…An acid catalyzed esterification process was carried out to evaluate the low content of FFA in the treated SPO with the effects of other parameters such as molar ratio of methanol to SPO (6:1–14:1), temperature (40–80 °C), reaction time (30–120 min) and stirrer speed (200–800 rpm). The results showed that the FFA of SPO was reduced from 23.2% to less than 2% FFA using 0.75% wt/wt of sulphuric acid with the molar ratio of methanol to oil of 8:1 for 60 min reaction time at 60 °C. …”
