NSCR Catalysts for Marine Engines

Engine exhaust has been effectively treated by catalytic converters since the 1970’s when the first automobile catalysts were placed on cars. Now EPA has a new requirement for catalytic converters on spark ignited, marine gas engines. The Environmental Protection Agency determined that for engines built after January 1, 2010, that are less than 500 HP, they would need to meet certain emission requirements. Why catalytic converters? Catalytic converters use chemistry to remove most of the hydrocarbons, nitrogen oxides and carbon monoxide from exhaust fumes. The emissions removed are some of the most harmful to our environment and air quality.

 

For recreational boat owners, the engine and exhaust system is now more complicated with additional sensors and electronics. To make sure the catalytic converter is working properly, oxygen sensors are required in the exhaust stream before and after the catalytic converter to measure the fuel/air mix in the exhaust. The oxygen sensors report to the engine’s electronic controls to adjust the fuel/air mixture as necessary (to achieve the stoichiometric air to fuel ratio of 14.7 to 1) and to deliver an exhaust gas mixture that the catalytic converter can clean up, leading to the fewest harmful exhaust emissions. At these stoichiometric conditions, a “three-way” catalyst can be employed, which allows the catalyst to eliminate Carbon Monoxide (CO), Hydrocarbons (HC) and Nitrogen Oxides (NOx) all at the same time with the same catalyst.

Product Types for Emission Control

Activated Carbon Monolith

In chemical process applications, ACMC® catalysts can be used for continuous hydrogenation reactions in many areas where traditional GACC (granular activated carbon catalysts) are currently used.

Monolithic Catalysts

Our monolithic solutions include activated carbon, ceramic, and metallic catalysts that have great applications for engine emissions control and industrial air pollution.

Particulate Systems

Our particulate systems include extrudates, precious metal spheres and saddles for regenerative air pollution control.  Enjoy benefits like 95% heat recovery.

RTO/RCO Media

We offer unique designs, such as our ceramic honeycomb, that provides excellent benefits including high resistance to thermal shock and solid thermal mass for effective heat exchange.
