Transport and reaction in catalytic wall-flow filters

Catalysis Today, 2005
Abstract Diesel particulate filters composed of so-called wall-flow monoliths are well established devices for diesel particulate abatement. Recent improvements in production technology allow implementation of full-featured catalyst functionality in the filter walls.

Analysis on filtration characteristic of wall-flow filter for ash deposition in cake

Journal of Aerosol Science, 2016
Abstract Based on the characteristics of ash cake deposition, the single channel model and the packed bed model, a mathematical model of filtration process of wall-flow filter for ash deposition in cake has been proposed. The effects of the amount of ash load and the distribution of ash deposition in cake on the filtration characteristic of filter ...

Ignition analysis of wall-flow monolith diesel particulate filters

Catalysis Today, 2004
Abstract During regeneration the diesel particulate filter (DPF) is a dynamic system whose trajectory depends on various parameters, especially the inlet gas temperature. Parametric sensitivity signifies large changes in the DPF trajectory induced by small changes in parameters across threshold values. This is a form of critical behavior and can lead

Wall-flow filters with wall-integrated oxidation catalyst: A simulation study

Applied Catalysis B: Environmental, 2007
Abstract Diesel soot abatement via diesel particulate filters composed of so-called wall-flow monoliths is well established. Today, due to recent improvements in the production technology full-featured catalyst functionality can be implemented in the filter walls.

Flow maldistribution measurements in wall-flow diesel filters

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2004
Understanding the flow maldistribution phenomena inside porous ceramic diesel particulate filters and their effects on the pressure drop and regeneration characteristics is important for the successful design and modelling of this class of exhaust aftertreatment system.
