Abstract
High energy (e.g., ultrasonic) mixing of a liquid hydrocarbon feedstock and reactants comprised of an oxidation source, catalyst and acid yields a diesel fuel product or additive having substantially increased cetane number. Ultrasonic mixing creates cavitation, which involves the formation and violent collapse of micron-sized bubbles, which greatly increases the reactivity of the reactants. This, in turn, substantially increases the cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. Alternatively, an aqueous mixture comprising water and acid can be pretreated with an oxidation source such as ozone and subjected to ultrasonic cavitation prior to reacting the pretreated mixture with a liquid hydrocarbon feedstock.
