Tests for CO_2 absorption by Rotating jetting bed was studied with MA aqueous solution.The influence of experimental conditions on CO2 absorption rate,including rotor speed, absorption temperature,absorbent flow rate,gas flow rate and CO_2 concentration was investigated. The results showed that CO_2 absorption rate reached to 158.35 mol/s,in the conditions of absorption temperature 40℃,absorbent flow rate 1 m~3/h,gas flow rate 12 m~3/h,rotor speed 1000 r/min.
