Automotive Catalysts

For further information and pricing, please get in touch with us.

Automotive catalysts are employed to restrict and reduce the emission of gases that are detrimental to our environment. 

Carefully controlled catalysis speeds up and facilitates the chemical reactions required to rapidly reduce the toxicity of emissions.

Overview

 At Hiden, we design quadrupole mass spectrometer systems that are fundamental to research and development (R&D) into the treatment of potentially harmful gaseous and particulate byproducts from automotive exhaust systems.

Effective Reduction & Removal Processes

NOx Storage and Reduction (NSR)

The catalytic removal of nitrogen oxides (NOx) from exhaust fumes is one of the key challenges for automotive catalysts. One promising candidate technology is NOx storage and reduction (NSR) by  use of the reduction materials CO, H2 and hydrocarbons provided from the engine during rich-burning cycles.

Lean NOx trap (LNT)

A lean NOx trap (LNT) is a catalytic system that removes nitrogen oxides from combustion engines and stores them under lean conditions, where they are reduced to less harmful nitrogen-containing species. Yet the mechanism whereby NOx is catalytically reduced to nitrogen (N2) is not well understood. This is exacerbated by conventional gas analyses and catalyst characterization processes. Hiden gas analysis systems can help researchers explore complex reaction mechanisms such as LNT regeneration, with spatially resolved data enabling deeper insights into catalyst performance.

Hiden Analytical’s Services

Depleting the harmful emissions of the automotive industry at large is a global environmental imperative. At Hiden Analytical, we are pleased to supply advanced gas analysis systems that can support R&D efforts into cleaner systems for greener roads. Contact us today if you would like to learn more.
