The 25th North American Meeting of the North American Catalysis Society, held in Denver from 6/4-9/2017, covers novel catalysis and catalyst systems for vehicle emissions control, both from gasoline and diesel engines. For gasoline engines, novel catalyst formulations with lower precious metal loading, and higher sulfur tolerance are currently being studied. For diesel engines, research on lean-NOx trap catalysts is currently focused on improving the selectivity, focusing on mechanisms of N2O formation, and on improving the sulfur tolerance. Promising new catalytic systems, namely Passive NOx Adsorbers have been developed to control NOx emissions at very low temperatures during engine start up periods. Diesel Particulate Filters continue to be used for the control of particulate emissions, with an important new goal to achieve not only the abatement in terms of mass as dictated by current regulations, but also in terms of particulate number, to meet the upcoming regulations.

Abstract
The 25th North American Meeting of the North American Catalysis Society, held in Denver from 6/4-9/2017, covers novel catalysis and catalyst systems for vehicle emissions control, both from gasoline and diesel engines. For gasoline engines, novel catalyst formulations with lower precious metal loading, and higher sulfur tolerance are currently being studied. For diesel engines, research on lean-NOx trap catalysts is currently focused on improving the selectivity, focusing on mechanisms of N2O formation, and on improving the sulfur tolerance. Promising new catalytic systems, namely Passive NOx Adsorbers have been developed to control NOx emissions at very low temperatures during engine start up periods. Diesel Particulate Filters continue to be used for the control of particulate emissions, with an important new goal to achieve not only the abatement in terms of mass as dictated by current regulations, but also in terms of particulate number, to meet the upcoming regulations.File | Dimensione | Formato | |
