Johnson Matthey has a long legacy in pre-reforming catalysts dating back to the 1960s and offers the CRG series of catalysts.
Our precious metal thermocouples are internationally renowned for highly accurate and reliable temperature measurement.
Mobile emission controls: a diesel particulate filter (DPF) removes particulate matter from diesel exhaust by physical filtration.
Mobile emission controls: Johnson Matthey’s NSC technology removes NOX from a lean gas stream and converts it to N2.
Mobile emission controls: three-way catalysts for cars, vans, light trucks and motorcycles.
Stationary emissions control: Johnson Matthey's MODULEX and DUALOX® catalytic converters for stationary engines were developed to satisfy the increasing demand for clean air technology combined with silencing.
Mobile emission controls: Johnson Matthey's Three Way Filter (TWF®) technology can reduce particle numbers by up to 99%.
Mobile emission controls: the SCRF® system integrates Selective Catalytic Reduction (SCR) with a soot filter – the next step for diesel nitrogen oxide control.
Mobile emission controls: selective catalytic reduction (SCR) systems work by chemically reducing nitrogen oxide to nitrogen.
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.
