    Sammanfattning : This PhD thesis is a summary of my work with thermal deactivated commercial three way catalysts (TWCs). An examination of catalytic properties, before and after accelerated aging was performed, such as light-off temperature, specific surface area (BET), noble metal dispersion and oxygen storage capacity was performed.
