Preparation and Characterization of Palladium Catalysts
… and systems currently available, such as the three way catalytic converter (TWC), have low activity below 400 °C in the catalytic process. Palladium catalysts were prepared by alternative methods including: preparation by wet impregnation or incipient wetness, drying by room temperature or …

Spatio-Temporal Dynamics of Reaction Zones in Catalytic Monolith Reactors
Catalytic monolith reactors are widely used in exhaust after-treatment systems. Unlike traditional chemical reactors which are commonly operated around certain steady-states, monolith reactors are almost always in transient states due to the nature of their applications. In this work, we studied …

Low-dimensional Models for Real-time Simulation of Internal Combustion Engines and Catalytic After-treatment Systems
… work, we propose a low-dimensional model of the three-way catalytic converter (TWC) for control and diagnostics. Traditionally, the TWC is controlled via an inner-loop and outer-loop strategy using a downstream and upstream oxygen sensor. With this control structure, we rely on the oxygen sensor …
