Catalyst carrier cordierite honeycomb ceramics for automobile

Used as catalytic converters of gasoline engines, the honeycomb ceramic catalyst substrates are coated by catalyst;at the same time , we improve the specific surface areas and cut down the heat capacity to increase the catalytic function. When the noxious emissions pass through, HC, CO and NOX will be converted into harmless components.

The necessary property of ceramic honeycomb catalyst substrate used in cars as follows:
1.High specific surface area: ensure exhaust gas could contact weigh catalyst enough.
2.Stable water absorption: guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste for too thick coating.
3.Warm up characters: after starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time.
4.Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it won't affect the performance of engine.
5.High intensity: substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed.
6.Perfect assembly: substrates are parts of exhaust; perfect appearance and exact dimension could ensure assembly perfect.

Ceramic Honeycomb catalytic converter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and high porosity has many advantages,for example, large surface area of slags collection,large inner surface area of filtering,small flow resistance,good filtering effect,etc.

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.
