Abstract: High energy (e.g., ultrasonic) mixing of a hydrocarbon feedstock and reactants comprised of an oxidation source, acid, and optional catalyst yields a liquid hydrocarbon product having increased cetane number. Ultrasonic mixing creates cavitation, which involves formation and violent collapse of micron-sized bubbles, which greatly increases reactivity of the reactants. Cavitation substantially increases cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. An aqueous mixture comprising water and acid can be pretreated with ozone or other oxidizer using ultrasonic cavitation prior to reacting the pretreated mixture with a hydrocarbon feedstock to promote cetane-increasing reactions. Controlling temperature inside the reactor promotes beneficial cetane-increasing reactions while minimizing formation of water-soluble sulfones.

Abstract: A method for combined reductive and oxidative treatment of liquid hydrocarbon feedstock to form upgraded liquid fuel having increased cetane number and reduced sulfur content. The yield of upgraded liquid fuel having a given cetane number is higher than processes than only increase cetane number by oxidative treatment. The feedstock can be initially hydrotreated to reduce sulfur content followed by oxidative treatment to increase cetane number. A first portion of a hydrotreated intermediate stream can be oxidatively treated to yield high cetane number blending stock, which is combined with a second portion of the hydrotreated intermediate stream to yield upgraded liquid fuel having increased cetane number and reduced sulfur content. Combining hydrotreatment with oxidative treatment facilitated by high energy cavitation maximizes yield and fuel quality.
