Abstract

L'invention concerne un procédé de fabrication d'esters d'alkyle à partir d'un mélange de glycerides et d'acides gras libres provenant principalement des déchets de boîtes à graisse. Le mélange est d'abord solvaté dans un alcool à point d'ébullition bas, après quoi le pH de la solution est porté à environ 1 à 2 par l'addition d'un acide afin d'effectuer l'estérification d'alkyle catalysé par acide. On traite ensuite la solution acide avec une solution concentrée d'alcoxyde pour porter le pH de la solution jusqu'à environ pH12 et effectuer la transestérification catalysée par des bases des glycerides contenus dans le mélange. On traite ensuite la solution qui en résulte avec un acide pour réduire le pH de la solution jusqu'à environ 2 et effectuer l'estérification catalysée par acides des sous-produits saponifiés résiduels. Le solvant à base d'alcool est évacué par distillation ou par toute autre technique appropriée, et les esters d'alkyle ainsi obtenus sont séparés de n'importe quels résidus restants et neutralisés des acides résiduels.
