The additive described consists essentially of a selected oxalkylated fatty amine or fatty amine derivative and a special mineral salt compound, preferably a metal soap. Said additive for heavy oils produces good emulsification and dispersion of asphaltenes and other high molecular compounds thereby resulting inter alia in increased storage stability, improved pumpability due to reduced viscosity of the oil and longer operational life of the filter systems. Further, said additive produces better combustion of heavy oils. The effective additive quantity for said oils amounts to 2 to 2,000 ppm. The oils described are specially adequate to be used as fuel for industrial installations and power stations and as fuel for boat motors.

L'invention a pour objet un additif essentiellement constitué d'une amine grasse oxyalkylée ou d'un dérivé d'une telle amine et d'un composé de sel métallique spécial, de préférence un savon métallique. Cet additif pour huiles lourdes provoque une bonne émulsification ou dispersion des asphaltènes et d'autres composés à haut poids moléculaire, ce qui entraîne, notamment, une stabilité au stockage élevée, une aptitude au pompage améliorée du fait de la moindre viscosité de l'huile et une plus longue durée d'utilisation des systèmes de filtration. Il assure en outre une combustion améliorée des huiles lourdes. La quantité efficace en additif dans ces huiles est de l'ordre de 2 à 2000 ppm. Les huiles selon l'invention sont utilisées notamment comme combustibles pour des installations industrielles et des centrales et comme carburants pour moteurs de bateaux.
