A method of ultrasound enhanced oil conjugation reaction

Abstract

The present invention discloses a method for enhancing the conjugation reaction of oils and fats using ultrasound. The method includes: filling a reactor with a macro-structured catalyst bed having a continuous three-dimensional interconnected channel network; introducing plant oils and gaseous reactants into the structured bed channels; applying a pulsed composite acoustic field generated by at least two independently controllable ultrasonic sources, which simultaneously includes axial and radial / tilted acoustic wave components, forming an interference acoustic field within the structured bed channels; wherein at least one ultrasonic source operates in pulse mode, with parameters satisfying: pulse width of 0.1-10 milliseconds, pulse interval time being 5-50 times the pulse width, and peak power density of 10-200 W / cm³. This invention can resolve the key technical challenges arising from the conflict between catalyst-acoustic field spatial matching, directional control of tri-phase interfaces, and continuous operation, which hinder industrial-scale amplification.
