Abstract

The great challenge for next years concerning the emission of diesel engines is to develop diesel particle filters (DPF) with catalytic regeneration systems. This work is focused on the global understanding of the diesel soot oxidation on sintered metal filters (SMF). Platinum is studied as reference catalyst. The first objective is to determine which of platinum quantity, platinum particle size, or platinum location exhibits the preponderant influence on the catalytic.

Abstract

Emission limits are being steadily tightened. This requires an ever increasing reduction of combustion generated pollutants. This book focuses on soot and NO and their heterogeneous interactions. With the help of laser spectroscopic methods and mathematical modeling of flames, a heterogeneous reaction mechanism for surface reactions can be validated and a significant influence on precursor reactions of soot formation can be shown.

Abstract

The properties of atmospheric particles - often also termed aerosol - have been the subject of scientific studies for several decades because of their effects on air quality, health, visibility, propagation of electromagnetic radiation in the atmosphere, and climate. However, despite intense research efforts, several knowledge gaps remain to be filled; the reason being related also to the complexity of the physical and chemical characteristics of these particles and of their dynamic interactions with the surrounding environment. One of the frontier topics in this scientific endeavor is the subject of this special issue: the morphology and mixing of atmospheric aerosol at the single particle level.
