We are professional at manufacturing Metal Catalytics and Ceramic Catalytics for Auto and Motorcycle exhaust system, like Honeycomb metallic substrate catalytic Honeycomb metal substrate catalytic. The material of outside shell is SUS441 and 444. The foil material of inside is OCr21Al6, and the thickness is 0.1mm. Compared to ceramic substrate, the metallic substrate has good heat conduction advantage. Metal Honeycomb Substrate for precious metal coating, our technology can make sure the low loss rate. It can be made of concentric round metal substrate, also can be made of duboule's metal substrate.
Features:
*Stainless steel shell,
*Foil material is OCr21Al6, foil thickness is 0.1mm
*Cell pieces per square inch: 100, 200, 300 and 400cpsi
*Shape and dimension is customized according to drawing provided
Application
*Round & Ovel metallic substrate for On-road vehicle
*Metallic substrate for small engine
*Metallic substrate for Off-road vehicle
*Metallic substrate for industrial catalyst
*Specific structure metallic substrate for other application
Metal-based monolith substrate offers many advantages in comparison with a ceramic one, for instance:
Shorter light off time;
Less risk of overheating
Less back pressure;
Larger effective area
Greater catalytic capacity
Smaller and more flexible design
Thinner walls
Higher mechanical strength
Better resistance to thermal shock
Working principle
Catalytic converter is a device used to reduce the toxicity of emissions from an internal combustion engine.
Reduction of nitrogen oxides to nitrogen and oxygen:
2NOx xO2 + N2
Oxidation of carbon monoxide to carbon dioxide:
2CO + O2 2CO2
Oxidation of un-burnt hydrocarbons (HC) to carbon dioxide and water:
CxH2x+2 + [(3x+1)/2]O2 xCO2 + (x+1)H2O
