Ceramic Catalyst Substrate

Ceramic Catalyst Substrate for exhaust purification

The use of honeycomb ceramics is very wide, and the introduction is as follows: When honeycomb ceramics are used as catalyst carriers, they are mainly used in automobile exhaust purification, boiler exhaust denitrification (NOx), industrial exhaust deodorization, and removal of toxic and harmful gases. The honeycomb ceramic catalyst carrier for automobile exhaust purification is mainly cordierite honeycomb ceramic carrier coated with γ-Al2O3. The porous and thin-walled honeycomb ceramic can filter and purify the carbon particles in the diesel engine gas exhaust gas (about 500°C).

Gasoline ceramic carrier

This product is made of leather lapis, after being coated with a catalyst, it is applied to the exhaust gas purification treatment of gasoline vehicles to catalytically convert the exhaust gas emitted by gasoline vehicles.

The products meet the requirements of various specifications and models of motor vehicles, as well as meet the Euro III and more stringent emission standards. The size and quality can be customized according to customer needs.

Features

◆Low back pressure ◇Small thermal expansion coefficient

◆Large specific surface area ◇High compressive strength

Product performance

◆Good consistency of water absorption ◇Good thermal shock resistance and thermal shock resistance

Show details

1)High purification rate, long life and low ignition temperature.

2)Thin hole wall,High compressive strength.

3) Strong adhesion increases the activity of the catalyst.

4) High temperature resistance,Excellent resistance to chemical erosion, strong thermal shock resistance and thermal shock resistance

5) Customizable,The product is universal and various models can be customized in size

The harmful gas discharged from the engine is turned into harmless gas through the three-way catalytic converter.

Catalyst active ingredients

Ming Rh-the main component in the catalytic reduction of nitrogen oxides

Platinum Pt-mainly catalyzes the oxidation reaction of carbon monoxide and hydrocarbons, and Rh-catalyzes the oxidation of carbon monoxide and hydrocarbons

Co-catalysts (rare earth elements such as bowls, steel, etc.)-have no activity or little activity, but can improve the performance of active components
