Diesel oxidation catalyst (DOC)

Mobile emission controls: many diesel particulate filter (DPF) systems incorporate an oxidation catalyst, either as a coating on the filter or as a separate element.

Diesel particulate filter

Mobile emission controls: a diesel particulate filter (DPF) removes particulate matter from diesel exhaust by physical filtration.

NOx storage catalyst (NSC)

Mobile emission controls: Johnson Matthey’s NSC technology removes NOX from a lean gas stream and converts it to N2.

Ammonia slip catalyst (ASC)

Mobile emissions control: Johnson Matthey’s ASC technology removes residual ammonia (NH3) from upstream ammonia dosing systems, converting it into nitrogen (N2) and water (H2O).

SCRT system technology

Mobile emission controls: the SCRT® system is more than simply a combination of a CRT® system and an SCR system.

Selective catalytic reduction (SCR)

Mobile emission controls: selective catalytic reduction (SCR) systems work by chemically reducing nitrogen oxide to nitrogen.
