Catalytic Substrates and Cleaning Services
Our leadership in
technology, business
processes, and operational
excellence creates products
and services capable of
achieving the highest
level of client satisfaction
and long-term loyalty
throughout the global
energy industry.
The Dresser-Rand brand represents high quality catalytic systems and
replacement substrates for most converter housings being produced today.
There is a difference in our quality, manufacturing processes and cleaning
capabilities because today’s high technology coatings require careful application,
packaging, installation, and cleaning to assure regulatory compliance and long life.
Catalytic substrates – The catalytic substrate is the heart of the system and will
require periodic replacement. The catalytic converter in conjunction with your
air-fuel-ratio control keep you in compliance by choosing the best quality products
available. Our replacement substrates are available in many standard sizes and
are competitively priced.
How The Catalytic Emissions System Works
Central to the catalytic converter/catalytic silencer is the catalyst substrate, comprising a cordierite (ceramic) or metallic foil honeycomb with flow-through channels,
coated with a thin layer of catalytic materials. The number of channels in a substrate
is typically between 200 and 400 cpsi (cells per square inch) for engine applications. This large number of channels provides a high geometric contact surface for
the exhaust gas to pass through, enabling catalytic reactions to occur. The catalytic
materials coated onto the surfaces of the channels consist of a refractory inorganic oxide, various substances which act as chemical promoters and stabilizers,
and a combination of precious metals that can include platinum, palladium
and rhodium. The actual formulation of the coating and precious metals
depends on the type of engine application. Dresser-Rand offers two main
types of catalyst formulas for industrial engines:
•tThree-way/NSCR catalysts to simultaneously reduce oxides of
nitrogen (NOx), hydrocarbons (HC) and carbon monoxide (CO) from
stoichiometric-operating engines

Oxidation catalysts to reduce non-methane hydrocarbons (NMHC) and
CO from lean-burn engines. Oxidation catalysts also can be used with richburn engines if the engine is set to operate with excess oxygen in the exhaust, or if
air is injected into the exhaust upstream of the catalyst.
