EURO 4 Alumina Honeycomb Ceramic Catalyst Carrier Support High Flow Universal

EURO 6 Alumina Honeycomb Ceramic Carrier

Product Description

Honeycomb ceramic monolithic carrier has a small specific surface area, which can not effectively achieve gas-solid contact. Generally, a porous material is coated on its wall to support catalytic active components, and alumina and its mixture with other oxides are usually selected. Among various crystal forms of alumina, γ-Al2O3 has strong adsorption capacity and large specific surface area, which is the main coating material used at present. The γ-Al2O3 coating generally accounts for 5-15% of the weight of the carrier, and the specific surface area of the carrier can be increased to over 50-150m2/g by coating with alumina coating, thus providing enough surface area of the catalyst to ensure the efficient catalytic reaction. However, the thermal stability of γ-Al2O3 is poor. When the temperature is higher than 1000°C, it will change into α-Al2O3 with small specific surface area (< 10 m2/g), and the catalyst activity will decrease. Therefore, in order to prevent γ-Al2O3 from deteriorating at high temperature, rare earth or alkaline earth oxides such as Ce, La, Ba, Sr and Zr are usually added as additives to enhance the thermal stability.
