In multiphase reaction systems, the mass transfer between the different phases usually plays a crucial role. The mass transfer rate depends on various factors, such as the concentrations and the operating conditions as well as the interface between the phases. For the model-based selection and design of a suitable reaction apparatus, the description of the mass transport is therefore essential. One measure of the efficiency of mass transport is the experimentally accessible mass transfer coefficient.

The hydrogenation of levulinic acid to γ-valerolactone constitutes a gas / liquid reaction system in which the reaction takes place only in the liquid phase using a dissolved catalyst. For this reason, the gaseous hydrogen must enter the liquid phase in order to be able to react there with the levulinic acid.

The aim of this work is the experimental determination of the mass transfer rate of hydrogen in levulinic acid / γ-valerolactone as well as the development of a suitable mass transfer model.
