摘要：
It is the purpose of this paper to check on the applicability of the authors' equation to suspension bubble columns, i. e. , fluidization by gas-induced liquid motion with no net liquid flow. Specifically, whether the relation holds also for particle mixtures is investigated. The volumetric mass transfer coefficients in suspension bubble columns and three-phase fluidized beds can be described by the same relation if the solids fractions at the bottom are considered. It is concluded that at moderate dispersion heights the suspension properties at the gas distributor determine the overall column performance.
