Catalysts for Oxidation and Reduction Applications
Oxidation of CO and hydrocarbons including formaldehyde and acrolein with high sulfur tolerance and low conversion of SO2 into SO3 for diesel and fuel oil applications. Also available: Special DOC catalysts for the oxidation of NO to NO2
Oxidation of CO and hydrocarbons and the simultaneous reduction of NOx into CO2, water and nitrogen in rich-burn applications with air-fuel-ratio control (lambda control)
Catalyzed wall-flow filters for the efficient removal of particulate matter and the combustion of soot at low temperatures in lean-burn applications.
Catalysts for NOx and N2O Reduction. These catalysts convert harmful ammonia and nitric oxide emissions into harmless nitrogen gas and water across a variety of processes.
NOx emissions are reduced by ammonia or urea in SCR systems in lean-burn applications. Low, medium and high temperature variants are available designed to work across a wide range of space velocities (up to 60.000 h-1). The EnviCat series is comprised of VWT (Vanadium, Tungsten, Titanium Technology) or transition metal exchanged zeolite technologies.
Oxidation of NH3 slip into N2 with low NOx formation. These catalysts offer high-performance operation thru a broad temperature range and are capable of reducing ammonia slip. Additionally, high levels of NH3 conversion can be achieved with only low formation of N2O or NOx
EnviCat NOx Blue and Red catalyst series form mainly N2 with a selectivity typically above 90%, while EnviCat NOx Red catalyst series are capable to reduce N2O using either ammonia, hydrogen or hydrocarbons as reductants
A wide variety EnviCat catalysts are available in a wide variety of forms and cell types. In engine emission control, either metal or ceramic; substrates are used typically in round or rectangular shapes. Our catalysts can be customized based on individual requirements: every project is carefully reviewed by our engineers to ensure that the catalyst design meets or exceeds the required emission reduction and engine performance.
