Abstract: Based on CO₂-NaOH system，the absorption performances of rotating packed bed with the gas-liquid distribution inducer were investigated. Furthermore，the characteristics of the absorbent flow and the performance of mass transfer resulted from the three different installation forms and structures of the gas-liquid distribution inducer were discussed. The experimental results showed that the absorption performance of rotating packed bed could be influenced by the installation of the liquid distribution inducer，when used the liquid distribution inducer in clockwise deflection and the gas distribution inducer in radial without deflection，the gas and liquid two phase were downflow contact，it can prolong the contact time of liquid absorbent and gas，obtained better mass transfer effect. Based on CO₂-NaOH system， the mass transfer coefficient in the rotating packed bed with gas-liquid distribution inducer could be 2. 83 times than that without the inducers，and the removing rate of CO₂ was increased from 43. 34% to 80. 00%.
