Abstract:

Transesterification is the predominant process in the conversion of vegetable oils into biodiesel fuel. In this process, triglycerides are reacted with an alcohol, ethanol or methanol, and catalyst or base. Niobium materials are presently of great interest in heterogeneous catalysis where they are used as catalyst active ingredient, carrier or auxiliary agent. Ammonium niobium oxalate is an excellent watersoluble complex. It is insensitive to moisture and easily handled in ambient atmosphere. In this study are shown the results of using ammonium niobium oxalate as a catalyst to prepare biodiesel.
