摘要：

Fine Bubble Jet reactor (FBJR) is designed for the enhancement on mass transfer of gas liquid with the generation of fine bubbles. The mass transfer and hydrodynamic characteristics were evaluated with the chemical absorption in FBJR. The effects of the ejector structure including downcomer length, opening ratio of outlet and the operation parameters (gas flow rate and liquid flow rate), were investigated with absorbent pH, CO2 removal efficiency and the gas holdup. Therefore, suitable combinations for the reactor can be selected for efficient gas liquid reaction in the industrial process. It was found that CO2 could be captured rapidly and efficiently by alkaline solution in FBJR system. Even neutral solutions also can achieve high CO2 removal efficiency. Comparison of CO2 absorption efficiency between FBJR and the bubbling reactor shows that the overall CO2 removal efficiency and mass transfer coefficient of FBJR are much higher than those of the bubbling reactor under the same operational conditions.
