A rotating packed bed (RPB) reactor is an effective device for intensifying the gas-liquid mass transfer process. By providing a higher gravitational acceleration, it significantly enhances the interaction force between the gas and liquid phases, thereby improving the reaction efficiency. Based on numerical simulation methods, this paper conducts a detailed study on the gas-liquid mass transfer process in the rotating packed bed reactor, with a focus on analyzing the gas-liquid interface behavior, fluid flow characteristics, and influencing factors of the mass transfer process under high-gravity conditions. The rotating packed bed reactor can effectively accelerate the gas-liquid mass transfer process; especially under high-gravity conditions, the reduction of bubble size and the intensification of liquid-phase flow greatly improve the reaction efficiency. The simulation results provide an important theoretical basis for optimizing the design and operation of rotating packed bed reactors.
