This study investigates the mass transfer intensification in the absorption of carbon dioxide (CO₂) into a monoethanolamine (MEA) solution enhanced by TiO₂ nanoparticles in a typical rotating packed bed (RPB). The overall volumetric gas phase mass transfer coefficients (${\text{K}}_{\text{G}}\text{a}$) were investigated in a counter-current RPB with blade packings. The effects of TiO₂ and MEA concentrations, rotational speed, initial concentration of CO₂, gas and liquid flow rates on ${\text{K}}_{\text{G}}\text{a}$ were specified. The rotational speed had positive effects on K_Ga. It is deduced that TiO₂ nanoparticles led to enhanced CO₂ capture efficiency of over 26.9 % and enhancement in K_Ga from 7.5%–96.1% for MEA based TiO₂ suspension in comparison with MEA solution without nanoparticles. Therefore, TiO₂ nanoparticles can augment the mass transfer coefficient and intensify the CO₂ absorption, even in a high-efficiency equipment like a high gravity RPB.

这项研究研究了在典型的旋转填充床（RPB）中二氧化碳（CO 2）吸收到由TiO ₂纳米颗粒增强的单乙醇胺（MEA）溶液中的传质强化。气相总体积传质系数（${\text{ķ}}_{\text{G}}\text{一种}$）在带有叶片填料的逆流RPB中进行了研究。TiO ₂和MEA浓度，转速，CO 2初始浓度，气体和液体流速对${\text{ķ}}_{\text{G}}\text{一种}$被指定。旋转速度对K _G a产生积极影响。据推论，与不含纳米颗粒的MEA溶液相比，基于MEA的TiO ₂悬浮液使TiO ₂纳米颗粒提高了26.9％的CO 2捕集效率，并使K _G a从7.5％–96.1％提高。因此，即使在诸如高重力RPB的高效设备中，TiO ₂纳米颗粒也可以增加传质系数并增强CO 2的吸收。
