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).
Mobile emissions control: A Catalysed soot filter (CSF) is a coated Diesel Particulate Filter (DPF).
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.
Mobile emission controls: Johnson Matthey’s NSC technology removes NOX from a lean gas stream and converts it to N2.
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: Johnson Matthey's Three Way Filter® (TWF®) technology can reduce particle numbers by up to 99%.
Mobile emission controls: three-way catalysts for cars, vans, light trucks and motorcycles.
Stationary emissions control: A fuel burner will be used to regenerate the filter when the machine has stopped operating. Air from a small pump is heated to >600°C and blown through the filter to remove the carbon.
Stationary emissions control: These systems use mains electrical power. The regeneration units may be mounted on the machine as an on-board control system, wall mounted or as an off-board control system.
