Automotive catalyst development using FT-IR spectroscopy and mass spectrometry
Published May 19, 1999 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Spring Conference
A dedicated FT-IR analyzer and soft-ionization mass spectrometer have been used to measure the formation, storage, release and conversions of a range of nitrogen, sulfur and hydrocarbon species over different catalyst systems under steady- state and transient conditions. Such detailed analysis provides considerable understanding into the development and optimization of engine and catalyst systems which will be required to meet future European emissions legislation. Applications presented include lean-burn gasoline aftertreatment, diesel deNOx catalysis, effects of sulfur on catalyst efficiency and hydrocarbon traps within the exhaust gas ignition system.
