Abstract

L'invention concerne un procédé permettant de produire des acides gras libres insaturés et saturés à partir d'huiles collectées, de graisses collectées, graisses brunes, de déchets de collecteurs de graisse en tant que produit de départ. Le procédé décrit dans cette invention consiste à soumettre le produit de départ à un prétraitement, à une première étape de purification, à une étape de fractionnement, à une seconde étape de purification et, éventuellement, à une étape d'hydrogénation. Ce procédé permet d'obtenir des esters méthyliques d'acides gras libres insaturés et saturés, d'acide oléique et de stéarine.
