Products for diesel applications
Emission control products for diesel applications, for cars, vans, trucks, buses and more.
ExploreSelective Catalytic Reduction Filter® (SCRF®)
Mobile emission controls: the SCRF® system integrates Selective Catalytic Reduction (SCR) with a soot filter – the next step for diesel nitrogen oxide control.
ExploreDiesel 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.
ExploreDiesel particulate filter
Mobile emission controls: a diesel particulate filter (DPF) removes particulate matter from diesel exhaust by physical filtration.
ExploreNOx storage catalyst (NSC)
Mobile emission controls: Johnson Matthey’s NSC technology removes NOX from a lean gas stream and converts it to N2.
ExploreAmmonia 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).
ExploreSCRT system technology
Mobile emission controls: the SCRT® system is more than simply a combination of a CRT® system and an SCR system.
ExploreSelective catalytic reduction (SCR)
Mobile emission controls: selective catalytic reduction (SCR) systems work by chemically reducing nitrogen oxide to nitrogen.
ExploreProducts for gasoline applications
Emission control products for gasoline applications, for cars, vans, hybrids and more.
ExploreThree Way Filter (TWF®)
Mobile emission controls: Johnson Matthey's Three Way Filter (TWF®) technology can reduce particle numbers by up to 99%.
ExploreThree-way catalyst
Mobile emission controls: three-way catalysts for cars, vans, light trucks and motorcycles.
ExploreMethane oxidation catalysts
Clean air solutions: our system offers cost-effective, low-temperature oxidation of methane from active and abandoned coal mines.
ExploreHalocat
Our Halocat™ SC29 PTA emission control catalyst reduces air pollution from PTA manufacturing plants to meet clean air emission standards economically.
ExploreActivCRT® and ActivDPF ® diesel particulate filters
Diesel particulate filter systems / engines
ExploreSINOx - HT SCR catalyst
JM offers a high temperature SCR catalyst that can operate under a broad range of temperature conditions.
ExploreOxidation catalyst systems
Our portfolio offers our customers options for catalytic coatings on both metallic and ceramic substrates.
ExploreSUREOX sulfur resistant oxidation catalyst
Our SUREOX™ catalyst with proprietary washcoat technology designed for reliable durable oxidation performance in the presence of sulfur.
ExploreFormaldehyde oxidation catalyst
We are a leading supplier of VOC catalyst for the treatment of formaldehyde emissions.
ExploreAmmonia slip catalysts (ASC)
Designed to enhance SCR performance, these catalysts achieve greater NOx control in parallel with lower carbon monoxide emissions and minimal ammonia slip.
