The mass-transfer efficiency of a new vapor-liquid contactor-rotating packed bed was studied. Distillation experiment was doing with the ethanol-water system, in RPB that contained a rotor, with an outside diameter of 180 mm, inner diameter of 60 mm, axial depths of 40 mm. The result showed that the mass transfer efficiency of RPB increased correspond to the F and βin low rotating speed. Its HTU was 1.09～1.76 cm and its mass transfer model was set up.
