Ceramic Honeycomb Substrate is honeycomb-like structures with thousands of parallel channels. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. 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. The honeycomb substrate 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.
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. After coating with catalysts, this product is applied in catalytic converter of diesel vehicle to catalyze, convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV and Euro V.
