Leibniz Universität Hannover

Introduction

In the Institute of Phys. Chemistry and Electrochemistry of the Leibniz Univ. Hannover the group of Nano-structured host/guest-systems, membranes and membrane-reactors (http://www.pci.uni-hannover.de/~lgpcb) is specialized in the development of porous and non-porous membranes for separation and catalysis. Activities include the preparation and characterization, testing and optimisation of zeolite, perovskite and metal membranes. State of the art hollow fibre perovskite membranes for oxygen separation have been developed by a spinning technology with partners.

The competences

Development of perovskite materials with high oxygen flux and high stability under chemical environment. Processing of these perovskite materials to membranes with the geometry of fibers by spinning, capillaries and tubes by extrusion and planar disks by pressing. Evaluation of these materials for the separation of oxygen and hydrogen. Testing of chemical membrane reactors under practice-relevant conditions such as elevated pressure. There are always Humboldt Price laureates like Prof. Ruthven (Univ. Maine, US) or Prof. Saboungi (Univ. Orleans) present in this group, also Humboldt Research Fellows like Dr. Wang in perovskite membranes and Dr. Li in zeolite membranes. The department of J. Caro is at present involved in several national German BMBF-projects and DFG-projects as well as in direct contract research with different industrial companies (Volkswagen AG, Uhde GmbH, BASF) and last but not least member in the EU Network of Excellence InsidePores. The group comprises about 30 persons, the amount of additional money per year is about 1.3 Mio €.

The role in NEXT-GTL

Task leader 1.3: Development, preparation and characterization of mixed conduction oxygen transporting membranes. Involved in the scale-up.
