Abstract
A reactor containing a plurality of porous rotors is disclosed. A liquid sprayed in a direction from a rotating axis to the rotors is hit by the porous rotors, creating fine liquid particles, so that a mass transfer takes place between the surfaces of the liquid particles and a gas injected into the reactor, and thus a crystallization reaction is initiated. The crystallization reaction is confined by the amounts of the reactants contained in the liquid particles, and will stop as soon as one of the reactants is consumed, so that the resulting crystals can be controlled in nanometer level. The reactor of the present invention is also suitable for use in a liquid-liquid reaction, wherein two different liquids are separately sprayed in a direction from the rotating axis and hit by the porous rotors, and the resulting fine liquid particles of the two different liquids contact and react with each other, so that ultra fine particles are formed.
