In this study, corn oil as vegetable oil, chicken fat and fleshing oil as animal fats were used to produce
methyl ester in a biodiesel pilot plant. The FFA level of the corn oil was below 1% while those of animal
fats were too high to produce biodiesel via base catalyst. Therefore, it was needed to perform pretreatment
reaction for the animal fats. For this aim, sulfuric acid was used as catalyst and methanol was used
as alcohol in the pretreatment reactions. After reducing the FFA level of the animal fats to less than 1%,
the transesterification reaction was completed with alkaline catalyst. Due to low FFA content of corn oil,
it was directly subjected to transesterification. Potassium hydroxide was used as catalyst and methanol
was used as alcohol for transesterification reactions. The fuel properties of methyl esters produced in the
biodiesel pilot plant were characterized and compared to EN 14214 and ASTM D6751 biodiesel standards.
According to the results, ester yield values of animal fat methyl esters were slightly lower than that of the
corn oil methyl ester (COME). The production cost of COME was higher than those of animal fat methyl
esters due to being high cost biodiesel feedstock. The fuel properties of produced methyl esters were
close to each other. Especially, the sulfur content and cold flow properties of the COME were lower than
those of animal fat methyl esters. The measured fuel properties of all produced methyl esters met ASTM
D6751 (S500) biodiesel fuel standards.
