Specifications

Monolith catalysts are made of cordierite, and they are used for car catalytic converter. We can supply both ceramic element coated with precious metals of Pt, Pd, Rh and ceramic element without precious metals.

 

*We can produce 100CPSI, 200CPSI,400CPSI,600CPSI can be in the shape of round ,racetrack and oval.

*Specification can be customized, as the the customers requirement.

*Can be coated with the catalyst and the precious metal as the customers emission standards:Euro II, EuroIII and EuroIV and EPA standard and the Cariforlia standards.

 

They well match active components of catalysts, have thin pore wall, large geometric specific area, low thermal expansion coefficient and good thermal impact resistance, while widely used in various fields. The products are the ideal carrier for catalysts and heat exchanger of purifying waste gas in environmental protection and chemical industry, and also the ideal high-temperature filtering materials of the metallurgy and casting industry.

 

Monolith Catalysts Honeycomb has the unique construction, excellent surface function and thermal property, was widely used in the automobile tail gas purification, chemical effluent gas purification, chemical catalysis, connecting combustion, melt metals and thermal medium filtering etc.

 

Application: Automobile exhaust purification catalyst carrier, suitable for Automotive vehicle exhaust purifiers (European standard) supporting

*Max. Outside dimensions: Diameter 300mm, height 355mm
*Low thermal expansion coefficient
*High porosity of hole on the wall, good liquidity and uniform distribution
*High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong
*The pressure drop is small
*Cold start performance is good, low light-off temperature, high conversion efficiency

 

Monolith catalysts Advantages:
*High specific surface area: ensure exhaust gas could contact weigh catalyst enough.
*Stable water absorption: guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it is no waste for too thick coating.
*Warm up characters: ask exhaust resistance of substrate to engine low, so that it will not affect the performance of engine.
*Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it will not affect the performance of engine.
*High intensity: substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed.
*Perfect assembly: substrates are parts of exhaust; perfect appearance and exact dimension could ensure assembly perfect.
