Beschreibung
Zusammenfassung:	This invention is about the batch production of fatty acid alkyl esters using a novel catalyst, homogeneous alkali gel catalyst (HAPJEK). This invention is a process which provides a shorter transesterification time (approximately 30 minutes) in fatty acid alkyl ester production, a very short glycerine precipitation time (approximately 10 minutes) without any modification in reactor configuration. Moreover this invention is about the production of homogenous alkali polymeric gel catalyst (HAPJEK) which enables fatty acid alkyl ester production without neutralization and washing processes that are required to get a pure product in traditional transesterification process. Besides, this invention enables low cost production of fatty acid alkyl esters from crude vegetable and animal fats without any refining process and waste vegetable and animal fats without any filtration process. Moreover this invention covers utilization of polyelectrolyte gel in the batch production of fatty acid alkyl ester with heterogeneous catalysts.
