Petroleum residua are combined with water or an aqueous solution to form an emulsion which is then treated with ultrasound at a sufficient intensity and for a sufficient period of time to cause a conversion of the heavy hydrocarbon components of the residua to lighter components, thereby shifting the entire boiling point curve to lower boiling points. This allows one to draw a greater proportion of usable oil from the residua.

Selon l'invention, des résidus du pétrole sont combinés à de l'eau ou à une solution aqueuse afin de former une émulsion que l'on traite alors par ultrasons avec une intensité suffisante et pendant suffisamment longtemps pour entraîner une conversion des composants hydrocarbures lourds des résidus en composants plus légers, déplaçant de la sorte la totalité de la courbe d'ébullition vers des points d'ébullition inférieurs. L'invention permet de cette manière d'extraire une plus grande proportion d'huile utilisable des résidus.
