Continuous esterification of free fatty acids (FFA) from acidified oil with methanol was carried out with NKC-9 cation-exchange resin in a fixed bed reactor with an internal diameter of 25mm and a height of 450mm to produce biodiesel. The results showed that the FFA conversion increased with increas...
