Abstract
The circulating liquid velocity, gas holdup, bubble size distribution, and liquid phase oxygen transfer coefficient were measured in a mini‐scale external loop airlift bubble column (MELBC) with the liquid volume suspending enzyme‐free liposomes of varying diameters. These values were compared to those for liposome‐free MELBC, normal bubble column (NBC), and a larger scale airlift column. The liposomes suspended in the MELBC are incorporated into the liquid film around the bubbles, leading to the development of a foam layer, where the incorporated liposomes exert negligible effect on the oxygen transfer in the film.
