About the Book

Ce travail a étudié la synthèse, la caractérisation structurelle et spectroscopique et l'analyse du potentiel catalytique des catalyseurs pérovskites SrTiO3 et des pérovskites doubles Sr1-xKxTiCux/2O3, où x = 0,2, 0,3 et 0,5, dans la préparation de biodiesel par la voie éthylique. Sur la base de la structure hôte du titanate de strontium SrTiO3, des solutions solides contenant des atomes de cuivre et de potassium avec les stoechiométries suivantes ont été étudiées: Sr0.8K0.2TiCu0.1O3, Sr0.7K0.3TiCu0.15O3 et Sr0.5K0.5TiCu0.25O3, préparées par synthèse chimique à l'aide de la méthode du polyol modifié. L'étude catalytique a été réalisée en utilisant la catalyse hétérogène, les nanoparticules étant ajoutées à une solution contenant de l'huile végétale et de l'alcool éthylique. Le processus de transestérification a été réalisé dans un réacteur de laboratoire, développé au LaCCeF, avec un système d'agitation et une température contrôlée. Dans ce processus, les principaux produits formés sont le biodiesel et le glycérol résiduel. Tout au long des expériences, les paramètres du processus tels que le temps de réaction, la concentration du catalyseur, la température et le degré d'agitation ont été contrôlés. À la fin de la réaction, il a été possible de filtrer le biodiesel et le glycérol résiduel.
