Lifetime Predictions of Uncoated Metal-Supported Catalysts via Modeling and Simulation, based on Reliable Material Data

摘要

As has been shown, it is indeed possible in spite of the extremely complex interrelationships, to make well-founded prognoses with regard to the mechanical stability of metallic catalyst supports. The model illustrated forms the basis for this. However, additional specific material values will be required. Values taken from literature are not suitable for accurate lifetime predictions. Using this work as a basis, the influence of further parameters can be investigated, for example, the influence of lesser foil thickness and higher cell densities as well as the influence of coating composition and coating thickness. Also the changes in foil properties with time is of importance. Due to the findings established as part of the investigations described in the above, the use of metals as catalytic supports does allow calculations about lifetime predictions and this is a major advantage when modifying or developing new supports in the shorter times now required.
