采用空气-CO2-NaOH体系,对泡沫金属填料旋转床的气相压降特性和CO2吸收特性进行研究,研究结果表明：泡沫金属填料旋转床的气相压降随转速和气量提高而增加,与液量的变化无关;体积传质系数（KGa）随转速的提高先增大后缓慢降低,随气量的增加几乎呈线性减小,随液量的增加而增加。与常见的金属丝网填料相比,泡沫金属填料具有动平衡性好、传质效率高、压降低等优点。

With an air-CO2-NaOH system,the characteristics of gas pressure-drop and the absorption of CO2 in rotating bed with foamy metal packing have been studied.The results show that the gas pressure-drop of the rotating bed increased when the rotating speed or the gas flow was enhanced,and was independent of liquid flow.The volume mass-transfer coefficient(KGa)increased firstly then decreased with the increasing of rotating speed.KGa decreased linearly with the increasing of gas flow and increased with the increasing of liquid flow.Compared with the normal metal wire packing,the foamy metal packing has better kinetic balance,higher mass transfer efficiency and lower pressure drop.
