Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.
Ceramic substrate 20/40 process bauxite with high content finely and make it into small and round grains with different grain diameters like 0.45mm-0.90mm, 0.09mm-0.224mm with chemical agents and transformation agents. Finally fire them under high temperature. In this way, high strength fracturing propping agent is finished. It has high strength, low breaking rate, good sphericity, etc. Under closing pressure. It is the best product for stratum fracturing transformation of oil and gas field at present.
Applications:
Ceramic Honeycomb Substrate is mainly used for supporting fissure of stratum fracturing transformation of deep oil and gas field. Enhance permeability of stratum Circulate oil gas. Increase output of oil gas
Features:
*High specific surface area: Ensure exhaust gas could contact weigh catalyst enough
*Stable water absorption: Guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste for too thick coating
*Warm up characters: After starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time
*Low exhaust resistance: Ask exhaust resistance of substrate to engine low, so that it won't affect the performance of engine
*High intensity: Substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed
*Perfect assembly: Substrates are parts of exhaust; Perfect appearance and exact dimension could ensure assembly perfect
