An innovative alternative to hydrodesulfurization is the ultrasonically assisted desulfurization. High local temperatures resulting from ultrasonic cavitation change the chemical reaction kinetics of the desulfurization process. This effect allows for alternative – less expensive – catalysts or alternative desulfurization chemistry to be used.
Ultrasonication is an effective means to break cell structures. This effect can be used for the extraction of intracellular materials, e.g. starch from the cell matrix.Ultrasonication generates alternating high-pressure and low-pressure waves in the exposed liquid.
