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. The ceramic honeycomb substrate could be coated or non-coated with noble metals.
Ceramic honeycomb substrate is well known for its high specific surface area, low pressure drop, rapid light-off time and reliable & durable performance are achieved through high cell density of 400, 500 and 600 cpsi. All of these make our ceramic honeycomb an ideal catalyst substrate media for oxidation & reduction catalyst. Our ceramic honeycomb substrate with different specification and differnt cars for the car converter as per customers' requests. The ceramic substrate is made of cordierite, and it is used for car catalytic converter. The shape will be round, oval or racetrack. The usual CPSI for honeycomb ceramic substrate is 400.
