Advanced After-treatment Technologies for Automotive Applications

International APT Course
The Course on “Advanced after-treatment technologies for automotive applications” gathers worldwide renowned scientists and technologists, in order to provide a comprehensive picture of current challenges and solutions related to automotive-related air pollution. Moreover, the Course delivers fundamental knowledge on the involved complex phenomena, from the aftertreatment line scale down to the catalyst scale. The Course starts with an introduction having an engine-directed perspective, in order to describe the mechanisms of pollutant generation, the control of the engine to minimize them, and the developments driven by law regulations. Subsequently, the catalytic converters are individually considered: firstly, the oxidation of gaseous pollutants from either gasoline (TWC) or diesel (DOC) engines exhausts in structured reactors is described. Then, the abatement of soot within Particulate Filters is tackled from an experimental and modeling point view, with a multi-scale approach: soot-catalyst interactions are specifically addressed, with a focus on mechanisms and rational catalyst design. NOx abatement, which constitutes a tremendous problem nowadays given the gap between bench and on-road performance of catalyst converters, is presented through concurrent technologies: NSR (and specifically the Di-Air technology), SCR, NSR+SCR, and ammonia slip catalysts (ASC). The mechanisms, the catalysts, and the reactor-scale management from reaction engineering perspective, are widely described. The possible combination of these different technologies will be proposed too. Finally, the perspective of a major manufacturer of catalytic converters and diesel engines is given, aiming at understanding the practical trade-offs that have to be optimized in terms of reliability, durability, cost and customer acceptance of the available technologies.
