ABSTRACT:
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.
