Neue Entwicklungen in der Flüssigmembranpermeation mit gestützten Membranen

In a time of rising raw material prices und raw material shortage topics like recycling of heavy metal ions from aqueous solutions get in the focus of the public. Aim of the presented work is the development of a new apparatus design for liquid membrane permeation with support layers. The investigations are carried out in view of heavy metal recycling.     

Keramische Membranen: Materialien – Bauteile – potenzielle Anwendungen

Ceramic membranes can be divided into dense and porous membranes. The materials, microstructure, and manufacturing methods are described and insights into current research topics are given. By adapting the material properties and tailoring microstructures, membranes and components suitable for a variety of processes can be developed. In applications, a distinction can be made between pure gas separation and membrane reactors. In the latter ones, in addition to gas separation, a chemical reaction takes place on one or both sides of the membrane. Membrane reactors can be used to produce basic chemicals or synthetic fuels. The supply of gases can be of interest for power plants, cement, steel or glassworks as well as for the medical sector or for mobile applications.
