To ease the air pollution, vehicle makers have started to mount the exhaust pipe with catalyst convertor to purify the emission. The work principle is to embed the honeycomb ceramic with metallic catalyst, like Pt., Pd. and Rh, or precious-metal metallic oxide. When it is mounted to engine system, it will turn the HC. CO. and NOX into non-noxious H2O, O2, and CO2 after a series of chemical reactions.
Kerui chooses cordierite as main material for honeycomb ceramic for its chemical characteristics, like regulated dimensions, large surface area, quick thermal conductivity, high compressive strength, low thermal expansion coefficient and good thermal stability. Currently Kerui has supplied to many domestic catalyst makers.
Ceramic honeycomb heat accumulator, also known as high temperature combustion heat accumulator, is a key part of HTAC (high temperature air combustion) technology, and has been applicable in metallurgical industry furnace, like step wedge furnace, heat treatment furnace, forging furnace, melting furnace, radiant tube combustion, lifting furnace, hot blast furnace; in construction industry, applicable in all types of ceramic furnace and glasses furnace; petrochemical industry, applicable in all types of tube heating furnace, pyrolyzer and other industrial furnaces.
