Abstract:
Transesterification is the predominant process for converting vegetable oils into biodiesel. Nb2O5.nH2O is known to have strong surface acidity and it reportedly increases Lewis acid sites at temperatures higher than 500 ºC, whereas Bronsted acid sites are more abundant at temperatures between 100 and 300 ºC. This study, which is a continuation of other investigations of this research group, aims to implement a methodology for preparing methylic biodiesel through transesterification process of cotton, coconut and flaxseed oils, monitoring heat treatment of Nb2O5.nH2O catalyst ratios and different proportions of catalyst mass/oil mass.
