Stationary Engines and Gas Turbines

Reliable and efficient power supply has become increasingly important across the globe in recent years. State-of-the-art highly efficient power generation technologies include gas and diesel engines as well as gas turbines and fuel cells. Emissions from these engines exceed – in many cases – the desired emission levels. In combination with catalytic emission control as secondary measure, regulatory emission limits can be met and even surpassed, thus reducing the impact on health and the environment.

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 NO_x 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.
