SFB TR 63: Integrated Chemical Processes in Liquid Multiphase Systems; TP A10: Gas/Liquid Mass Transfer in Reactive Multiphase Systems

The amination of undecanal with hydrogen is a fast reaction. The effective rate of reaction may therefore be limited not only by the reaction kinetics but also by the transport of the gas through the liquid phase. Project A10 investigates the rate-limiting steps of mass transport and reaction for a gas component in reactive, catalyst-containing novel solvent systems. The mass transport in these systems is complex due to the multiple phases, phase interfaces, and transport pathways. Project A10 quantifies the volume-specific mass transport coefficients (kLa) in micellar solvent systems, thermomorphic phase systems, and Pickering emulsions. The goal of the project is to develop a fundamental understanding of gas/liquid mass transport in the reactive phase systems being considered in SFB/TR 63 and to provide a model that can describe the various transport pathways among all of the phases involved.
