Süd-Chemie HyProGen® Fuel Processing Catalysts for Fuel Cells and EnviCat® Catalysts for Emission Control
As a leading international catalyst supplier, Süd-Chemie offers a wide range of catalyst products for industrial applications.
For over 60 years Süd-Chemie has been a leader in the development and manufacture of base metal catalysts in a variety of unique formulations and shapes for the production of hydrogen. This long experience led to the creation of the HyProGen® brand, a new generation of catalysts for fuel cells that meet the unique requirements of stationary and mobile systems.
Süd-Chemie has been a leading supplier of EnviCat® catalysts for emission control since 1982. Its regional headquarters are in Germany, the US, Japan and India, acting in a global coordinated R&D, production and service network.
Catalysts for fuel cells
Current development efforts are focused on the key reaction steps for fuel processors based on a variety of feedstocks and fuel cell types.
- Desulfurization: HyProGen FCDS / ActiSorb® series – industry proven and new generation products and shapes for gas and liquid phase
- Reforming: HyProGen FCRS series – base and precious metal formulations for a wide range of hydrocarbon feeds; for system designs utilizing pre-reforming, steam, autothermal or partial oxidation
- Water gas shift: HyProGen FCS / ShiftMax® series – outstanding activity and stability using base and precious metal formulations
- CO purification: HyProGen FCM series – selective CO methanation for ultra-low clean-up of CO required for PEM-based systems
- Tar-reforming catalysts: purification of syngas from biomass gasification
- Off-gas purification: HyProGen FCCB series – base and precious metal catalysts to remove traces of hydrogen from the off-gas and ensure zero-emission systems
Catalysts for stationary engines and gas turbines
EnviCat® catalysts for emission control include:
- EnviCat DOC (diesel oxidation catalysts and oxidation catalysts): oxidation of CO and hydrocarbons/VOCs including formaldehydein lean burn applications; EnviCat DOC with high sulfur tolerance and low conversion of SO2 to SO3
- EnviCat TWC (three-way catalysts): oxidation of CO, hydrocarbons and simultaneous reduction of NOx for stoichiometric engines
- EnviCat cDPF (catalyzed diesel particulate filters): catalyzed wall-flow filters for the efficient removal of particulate matter and the combustion of soot at low temperatures; CARB Level 3+ and TÜV Verification
- EnviCat SCR (selective catalytic reduction catalysts): reduction of NOx by ammonia or urea in a SCR system; low, medium and high temperature variants are available as well as ammonia slip catalysts
Catalysts for industrial applications
Süd-Chemie offers a variety of catalyst products for industrial applications:
- EnviCat VOC oxidation catalysts for the reduction of organic emissions in industrial applications: honeycomb and bulk catalysts for the combustion of solvent vapors, hydrocarbon streams and other non-desired organic matter from industrial plants
- EnviCat NOx blue/yellow/red line (SCR catalysts for NOx reduction and catalysts for selective NH3 oxidation): honeycomb and bulk SCR catalysts based on iron, copper or vanadia for temperature ranges from 200°C to 600°C
- EnviCat N2O (SCR for laughing gas reduction): iron-based bulk catalyst for N2O conversion in processes based on Uhde’s EnviNOx® technology
Süd-Chemie and Clariant: stronger together
As of 2 July 2012, Süd-Chemie will be merged into Clariant Produkte (Deutschland).
Süd-Chemie, a member of the Swiss Group owned by Clariant, Muttenz, is a speciality chemicals company headquartered in Munich, Germany, and operating on a worldwide scale.
