Steam Reforming of Methanol with Nanostructured Copper-Catalysts

The aim of our project " Nanochemie für eine neue Automobiltechnik- Möglichkeiten zur Optimierung von kupferbasierten Katalysatoren für die Gewinnung von Wasserstoff aus Methanol" is the development of new and better catalysts that avoid the two major problems of the catalysts used today. The bad long term stability of CuO-ZnO-Al2O3-catalysts and the formation of a high level of carbon monoxide as by-product require a sophisticated process design around the methanol reforming reactor. Additional process steps are needed for catalyst regeneration and CO removal from the hydrogen steam in order to prevent poisoning of the fuel cell catalysts. Mechanistic, analytical and kinetic studies with the CuO-ZnO-Al2O3-catalyst tought us how to search for new catalysts and optimise them. The tasks within the project are devided amoung the five following institutes: Fritz-Haber-Institute of Max-Planck-Society, Berlin (Prof. R. Schlögl): Characterisation of Cu-catalyst structure by XRD, EXAFS, etc. MPI of Colloid and Interface Science, Golm (Prof. M. Antonietti): Preparation of new nano-scaled Cu-catalysts on different support materials MPI of Chemical Physics of Solid Materials, Dresden, (Prof. Steglich): Study of Cu-catalysts by NMR MPI für Kohlenforschung, Mülheim (Prof. F. Schüth) High Throughput Screening for new Cu-catalysts Technical University, Berlin, Prof. R. Schomäcker Kinetic studies with different Cu-catalysts and development of new reactor concepts for on-bourd steam reforming of methanol. The project is funded by the ZEIT-foundation, Hamburg.
