Selective Catalytic Reduction (SCR)

Selective Catalytic Reduction (SCR) that developed based on high quality cordierite material, with a special structure, has the advantages of high mesh, thin pore wall, large specific surface area, high compressive strength, low coefficient of thermal expansion and good thermal shock resistance is mainly used to purify NOx from diesel exhaust gas by ammonia selective catalytic reduction technology. Diesel Selective Catalytic Reduction (SCR) can also be used to purify NOx from Marine internal combustion engines.

Product details

Selective Catalytic Reduction (SCR) that developed based on high quality cordierite material, with a special structure, has the advantages of high mesh, thin pore wall, large specific surface area, high compressive strength, low coefficient of thermal expansion and good thermal shock resistance is mainly used to purify NOx from diesel exhaust gas by ammonia selective catalytic reduction technology. Selective Catalytic Reduction (SCR) can also be used to purify NOx from Marine internal combustion engines.

Vanadium-SCR catalyst can meet the requirements of diesel engine road EUO IV,EUO V and EUO IV emission standards for non-road small and medium power diesel engines; V-SCR catalyst has good sulfur resistance, low cost, high conversion efficiency between 350℃ and 450℃, and easy inactivation at high temperature.

Fe-SCR catalyst with excellent sulfur resistance, excellent medium, high temperature activityand hydrothermal stability is suitable for heavy-duty diesel and truck that do not have high requirements for oil quality.

Cu-SCR catalyst has excellent activity at low temperature, good hydrothermal stability at high temperature but poor sulfur resistance.

Bellows with Outer Braid

Bellows with outer braid as kind of exhaust flexible pipe is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler which makes the connection of the entire exhaust system flexible and plays a role in reducing noise.

Exhaust flexible pipe with outer braid that easy to install and extend the life of exhaust noise reduction system is mainly used for light trucks, small passenger cars and buses. In order to improve the noise reduction effect, an expansion joint or mesh sleeve can be installed in the bellows.

Bellows with Inner Braid

Bellows with Inner braid as kind of exhaust flexible pipe is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler which makes the connection of the entire exhaust system flexible and plays a role in reducing noise. The inner braid could reduce the exhaust noise and improve the noise elimination function of the exhaust system.
