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.
The ceramic substrate is made of cordierite, The cells density can be 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi. The usual cpsi (Cell Per Square Inch) for catalytic converter substrate is 400, the shape of ceramic substrate is round, racetrack, ellipse and other special shape according to the customer's requirement.
The ceramic substrate is made of cordierite, and it is used for car catalytic converter. The cells density can be 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi. The shape will be round, oval or racetrack. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals.
Heat exchanger Honeycomb Ceramic application:
*NOx purification system in the smoke of the thermal power plant
*The harmful gas purification system in rubbish burning
*Poison gas purification system in chemical and mining industries. The slag filter for casting production in the metallurgical industry. The catalyst substrate. Stuffing material for chemical industry colums and Contact combustion.
*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.
