PGM coated cordierite ceramic honeycomb carrier substrate monolith catalyst support

Ceramic honeycomb substrate is a new kind of catalyst monolith, which is widely used in automobile emissions purifying system and industrial exhaust gas treatment system. After coated with catalysts, this product is applied in catalytic converter of diesel or gasoline vehicle to catalyze, convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV, Euro V and Euro VI.

Advantage of Honeycomb Ceramic Monolith

1. Thin wall, high surface area.

2. Low coefficient of thermal expansion.

3. Low back pressure, good air flow.

4. Good thermal shock resistance and heat resistance.

5. High temperature resistance and chemical corrosion resistance.

6. High compressive strength and stable water absorption rate.

7. Accurate size control, good for encapsulation.

8. Low light off temperature and high conversion efficiency.

9. Ideal matching with different catalysts.

The ceramic monolith is made of cordierite, and it is used for car catalytic converter of gasoline engines. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals.

Advantage of ceramic monolith

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. Fast in temperature rising: 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.
