At Süd-Chemie, we have been developing and manufacturing catalysts to clean exhaust gases from combustion processes since the early 1980s. Our EnviCat® brand catalysts include:
EnviCat® Oxidation Catalysts:
For the oxidation of CO and hydrocarbons including formaldehyde, aldehydes, PAKs, NMHCs, VOCs, TOCs into CO2 and water in lean burn applications.
Also available: special oxidation catalysts for the oxidation of NO to NO2.
EnviCat® DOC (Diesel Oxidation Catalyst):
For the 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.
EnviCat® TWC (Three-Way-Catalyst):
For the 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).
EnviCat® cDPF (Catalysed Diesel Particulate Filter):
Designed as catalyzed wall-flow filters for the efficient removal of particulate matter and the combustion of soot at low temperatures in lean-burn applications.
CARB-Verification for EnviCat® cDPF as Level 3PLUS device for off-road applications.
EnviCat® SCR (Selective Catalytic Reduction):
For the reduction of NOx emissions by ammonia or urea in a SCR system in lean-burn applications. Low, medium and high temperature variants are available.
EnviCat® ASC (Ammonia Slip Catalyst):
Designed for the oxidation of NH3 into N2 with low NOx formation.
EnviCat® catalysts have been used to treat the emissions of installation running on:
