• A model for water flux through a PRO membrane is developed. • A validated model for temperature distribution over the membrane is also provided. • The effect of the solution temperatures on the membrane properties was highlighted. • It is shown how raising the feed solution temperature enhances the

The insights from this study allow fast membrane development for specific applications. With pore size, membrane thickness and hydrophobicity/ oleophobicity are adjustable on demand. The tested membranes show good performance in liquid–liquid extraction. State of the art in membrane contactors are p

It was shown that phase inversion is an interesting process to create complex porous structures in ceramics. This process was used to develop hollow fibre geometries. By their large specific surface area such fibres and capillaries possess a high potential in membrane applications. It could be shown

A membrane reactor with perovskite hollow fibres in combination with a commercial steam reforming catalyst is used to produce in a long term scale synthesis gas with a methane conversion of about 96%, a CO selectivity of 95% and at a H2/CO ratio of 2. By having the whole perovskite hollow fibre at 8

So far, large scale industrial separations with inorganic membranes and catalytic membrane reactors in process intensification do not exist. Two prominent developments which are near to a commercialization are discussed: perovskite membranes for oxygen separation and zeolite membranes for molecular

We have prepared dense ceramic hollow fibres based on perovskites. These fibres show a good permeability for oxygen with an excellent Presented at EUROMEMBRANE 2006, 24–28 September 2006, Giardini Naxos, Italy. 0011-9164/06/$– See front matter © 2006 Elsevier B.V. All rights reserved. doi:10.1016/j.
