摘　　要：A new submerged membrane emulsification apparatus using ceramic external membrane was introduced, which is attractive due to its simplicity, lower energy consumption, easier to integrate with other processes and scale-up. Using different pore size membranes, O/W emulsions with different particle sizes were prepared. The O/W emulsion with Sauter mean particle size of 1.98μm was obtained by using 0.69μm ceramic external membrane element, and the emulsion with Sauter mean particle size of 0.65μm was obtained by using 0.16μm external membrane element. The specific surface areas were respectively 3.78m 2·g -1and 10.8m 2·g -1, fit for extractive reaction and biphasic reaction.A new submerged membrane emulsification apparatus using ceramic external membrane was introduced, which is attractive due to its simplicity, lower energy consumption, easier to integrate with other processes and scale-up.
