Decreasing emission limits lead to the development of combined aftertreatment systems,
consisting of combinations of different catalyst technologies and particulate filters. Modeling …

The Nobel Prize in Chemistry 2007 awarded to Gerhard Ertl for his groundbreaking studies
in surface chemistry highlighted the importance of heterogeneous catalysis not only for …

Looking at exhaust-gas after-treatment systems in its entirety leads to further improvement of
emission control devices and to the accomplishment of future challenges such as lower …

The impact of catalyst distribution within the porous wall of a coated gasoline particulate filter
on its catalytic performance is investigated. Sections of catalyzed filter wall with different …

We utilize the recently developed concept of internal or intraphase mass transfer coefficient
to simplify the problem of diffusion and reaction in more than one spatial dimension for a …

The combustion characteristics of methane-air and propane-air mixtures in catalytic micro-
combustors was studied numerically in order to clarify the importance of transport in …

Mathematical models of reaction and transport in porous catalyst on three different scales
(nano, micro, and macro) are presented. Methodology is demonstrated on CO oxidation in …

Transport phenomena in millisecond reactors are poorly understood due to extremely short
contact times and nonequilibrium states. Numerical investigation of transport phenomena at …

This study concentrates on the external and internal mass transfer with multiple reactions in
the catalytic layer of a three-way catalyst (TWC). A single channel model accounting for the …
