Beschreibung
Zusammenfassung:	The invention provides a method that regenerates the bleaching capacity of spent clay, which has been used for purification of fats and oils, easily and simultaneously with production of a compound with which thermal recycling from oil components in the spent clay into biofuel is possible. That is, this method for producing purified fats and oils comprises: a method for producing regenerated clay characterized in that spent clay that has been used in fat and oil purification is mixed with a lower alcohol and an acid catalyst, and the extraction of oil components from said spent clay is performed simultaneously with an esterification reaction of the fats and oils and/or free fatty acids in said oil components with the lower alcohol to regenerate the bleaching capacity of the spent clay; the regenerated clay produced by said method for producing regenerated clay; and a process of bleaching fats and oils using said regenerated clay. Cette invention concerne un procédé qui régénère le pouvoir de blanchiment d'une argile usée, qui a été utilisée pour purifier des graisses et des huiles, de manière facile et simultanément à la production d'un composé permettant le recyclage thermique des composants huileux contenus dans l'argile usée dans un biocarburant. A savoir, le présent procédé de production de graisses et d'huiles purifiées comprend : un procédé de production d'argile régénérée caractérisé en ce que l'argile usée qui a été utilisée pour la purification de graisses et d'huiles est mélangée avec un alcool inférieur et un catalyseur d'acide, et l'extraction des composants huileux contenus dans ladite argile usée est mise en oeuvre simultanément à une réaction d'estérification des graisses et des huiles et/ou des acides gras libres dans lesdits composants huileux avec l'alcool inférieur pour régénérer le pouvoir de blanchiment de l'argile usée. Cette invention concerne également l'argile régénérée obtenue par ledit procédé de production d'argile régénérée ; et un procédé de blanchiment des graisses et des huiles à l'aide de ladite argile régénérée.
