Liquid–solid mass transfer in micropacked bed reactors with immiscible liquid–liquid two-phase flow

Herein, the liquid–solid mass transfer characteristics in micropacked bed reactors (μPBRs) operated with immiscible liquid–liquid two-phase flow is experimentally investigated. It is found that the overall volumetric liquid–solid mass transfer coefficient ( k s a ) increases with the total flow rate and the channel-to-particle diameter ratio, while decreases with the organic-to-aqueous phase flow rate ratio. A satisfactory correlation model for calculating k s a of the liquid–liquid μPBRs is developed. The new knowledge obtained would be useful in guiding the design and optimization of the liquid–liquid μPBRs.
