Honeycomb Ceramic/Metal Substrate Catalyst for Auto Exhaust System Pt Pd Rh
Honeycomb Catalyst
The material of the honeycomb ceramic substrate is mainly cordierite, and the honeycomb ceramic material for automobile exhaust gas treatment is often porous cordierite, whose main function is to provide an inert physical structure that supports the catalyst coating. In order to have a larger catalytic surface in a smaller volume, the surface of the substrate is made into a honeycomb shape. The advantages are large specific surface, low thermal expansion coefficient, excellent thermal shock resistance, strong acid and alkali resistance, and high mechanical strength.
Metallic catalyst substrates are made of thin metal foils. The advantages of metal substrates are their high geometric surface area, low pressure drop and improved flow properties associated with the thin walls. The foils in metallic substrates can be brazed/welded together to provide good mechanical durability and resistance to thermal shock.
