honeycomb ceramic catalyst

Ceramic honeycomb ceramiccatalysts have been widely used since the 1980s. They can be extruded in a variety of shapes and cell densities,they can carry a heavier amount of coating than metallic supports, which gives ceramics the advantage in applications where catalyst deactivators are present or where very high levels of precious metals are needed to reach the desired performance. Features: 1) Using honeycomb ceramics carrier that has many advantages, such as low cost, strong adhesive and active ingredient, and long life 2) Adopting late-model of rare earths to advance the heat resistance and activity of catalyst 3) Introducing transitional metal, alkaline earth metal and active material of little precious metal that has plenty of excellences, such as high purification rate, and low burning temperature 4) Making use of new-style of oxygen storing stuff that reduces the burning temperature of catalyst and complete transformation.The major technical parameters for cordierite are as below:1.
