Abstract
The present invention provides a novel system and method for sulphur and metal removal from crude oil and all liquid fuel fractions to biofuels by means of ultrasonic cavitation to enhance chemical reactions of said contaminants with sodium or potassium methylate and a water/fluoride mix in separate stages obtaining a solid form which is filtered out by the use of a centrifuge system. The resulting fuel is molecularly stable and cleaner than regular fuels.
