Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.
Because of it's features of corrosion resistances, large specific surface area, small heat resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. It's widely used in many fields. The gasoline engine tail gas purifier carrier coated with catalyst is suitable for and is currently one of the most important means to control tail gas purification for gasoline engine discharge of tail gas in motorized vehicles. Our honeycomb ceramics are characterized by unique honeycomb structure, low expansion coefficient, good thermal stability, large specific area and low pressure loss, and reach domestic advanced level.
Advantages:
*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
