Cordierite Ceramic Honeycomb Catalyst Substrate for Catalytic Converter
Product Description
Honeycomb ceramic catalyst carrier for automobile
Introduction: Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic substrate body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a variety of unobstructed parallel channels sized to through 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.
Application
*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc, for instance, utilized in exhaust catalytic converter, airfresher machine for hotel, restaurant, toilet and so on.
*Heat transfer agent: It can save 12% of energy in heat exchange, and it mainly utilized in heat recovery unit of RTO. Refractory stove: Low mass/volume, fast heat conduction. Gas burn distributing plate: Complete burn, energy saving is 10%.
*As filtrate substrate, they are generally utilized in food processing, environmental industry, metallurgical industry etc. For filtering particulate in industrial waste gas and bubble in liquid of molten melt and making the molten melt laminar so as to increase casting yields, also filtering impurities in juice, dextrose and sucrose etc.
