Abstract

La présente invention se rapporte à un mazout émulsifié et modifié et à son procédé de préparation, ledit mazout émulsifié et modifié étant obtenu par mélange des composants suivants: 40 à 50 % en poids de pétrole lourd, 10 à 25 % en poids d'eau adoucie, 0,1 à 0,5 % en poids d'un émulsifiant, 5 à 30 % en poids de pétrole léger, 1 à 15 % en poids d'un agent modificateur, et 7,5 à 15 % en poids d'un agent auxiliaire. La valeur de combustion de ce mazout émulsifié et modifié est comprise entre 8 000 et 13 000 KJ/kg. Ce mazout émulsifié et modifié peut être utilisé dans un dispositif de transport à faible vitesse et à moteur diesel ainsi que dans une chaudière à mazout.
