摘要:
La présente invention concerne un additif de lubrifiance pour carburant, notamment pour carburant gazole, directement issu de l'acidification d'une pâte de neutralisation obtenue par un procédé de raffinage d'une ou plusieurs huiles végétale et/ou animale. L'additif de lubrifiance selon l'invention est plus particulièrement destiné aux carburants présentant une faible teneur en soufre, par exemple inférieur à 500ppm (poids).
