A brief review is presented on the enhancing effects of fine particles on multiphase mass transfer in the first part of this paper. Some experimental results on the following aspects are shown and discussed: influence of fine particles on mass transfer parameters (kLa, kL, a), enhancement due to particles adsorption and catalyzing a chemical reaction, and effects of particle size. The second part of this paper proposes two kinds of hybrid process accompanied by ultrafine particles: adsorptive distillation and slurry catalytic distillation. Finally, prospective fields for additional research are proposed.
