Ammonia 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.

SCR catalyst elements and modules

Stationary emissions control: SINOX® honeycomb SCR and plate SCR catalyst are pre-installed in element frames or modules for durability and easy handling.

Formaldehyde oxidation catalyst

We are a leading supplier of VOC catalyst for the treatment of formaldehyde emissions.  

Oxidation catalyst systems

Our portfolio offers our customers options for catalytic coatings on both metallic and ceramic substrates.

SCR catalysts

Stationary emissions control: our advanced SCR catalysts can achieve high Hg0 conversions under a variety of power plant conditions for cleaner energy and cleaner air.

CompactSCR® NOx control systems

SOOTALERT monitor

Stationary emissions control: Companion product to the CRT® system that alerts operator when and how long to regenerate the diesel particulate filter.

Mixed oxide catalyst pellets and honeycombs

Stationary emissions control: Johnson Matthey’s SINOx® mixed oxide catalysts can be used alone or in combination with precious metal oxidation catalysts for more efficient and economical catalyst systems.
