Modeling the drying process of porous catalysts- impact of viscosity and surface tension

The distribution of catalytically active species in heterogeneous porous catalysts strongly influences their performance and durability within industrial reactors. A drying model for investigating this redistribution is developed and subsequently the impact of non-linear couplings of liquid viscosity and surface tension on hydrodynamics and redistribution of species during the drying process investigated. The gained insights are then used to exert control of the redistribution within the presented model by solely varying external process parameters.
