摘要：

Bubble column hydrodynamics influence important performance parameters like conversion, selectivity, and yield of a chemical reaction. Backmixing of the liquid phase and gas holdup are thereby of particular importance. In order to determine these parameters, a number of correlations exist in the literature. These correlations are mainly derived from small-scale equipment operated under atmospheric conditions using the physical system air/water. Published experimental results regarding gas holdups and dispersion in bubble columns operated under high pressure are discussed and a recommendation for further research is given.
