The diesel oxidation catalytic converter (DOC) has been extensively used by the underground mining industry to reduce exposure of workers to carbon monoxide (CO) and hydrocarbons (HC) emitted by diesel engines. The effects of those devices on the gaseous and diesel particulate matter emissions strongly depend on catalyst formulation. Recently, certain formulations of catalytic coatings used in DOCs marketed to underground mining were scrutinized for their potential to adversely affect emissions of the highly toxic compound, nitrogen dioxide (NO2). This study was conducted to get a better understanding of the effects that contemporary and emerging DOC technologies have on gaseous emissions.
