Honeycomb Ceramic

With the characters of big specific surface area, big thermal capacity, low thermal expansion coefficient, strong corrosion resistance, and excellent heat endurance, honeycomb ceramic is widely applied in industries of chemical, metallurgy, gas and environment protection. Generally, it's applied as Mass transfer packing Big surface area, flow distributed evenly, and high performance of separation Catalyst carrier It can lower oxidation temperature of organic chemical. It can carry noble metal catalyst, e.g. platinum, rhodium, or palladium to form the catalytic converter to purify tail gas applied in automobile industry. Thermal storage agent It's applied in the process of heat exchange. Energy saving for the thermal storage unit is over 10%. Refractory stove packing Low bulk density, fast heat transmission, and high thermal efficiency Gas distributing plate It distributes heat evenly and facilitates complete combustion, which energy saving can be over 10%

Honeycomb Ceramic Thermal Storage Series honeycomb ceramic thermal storage are developed specially applying in steel heat furnace for heat storage and release.  With the characters of big specific surface area, high thermal storage capability, low pressure drop and excellent thermal shock resistance, honeycomb ceramic thermal storage is widely applied in various industries, especially for metallurgy of steelmaking furnace, energy saving of steel-rolling stove, NOx purification system of thermal power plant, waste gas purification system of incinerator, toxic gas purification system in chemical and mining industries, heat exchange system, etc. As for the material of honeycomb ceramic thermal storage, its principal crystalline phase is mullite. As for main chemical ingredients inside,  AL2O3 occupies about 60%, SiO2 about 38%, and others about 2%.

Honeycomb Ceramic Catalyst Carrier

With the characters of thin cell wall, big specific surface area, high compressive strength, low pressure drop and low bulk density, honeycomb ceramic can be used as catalyst carrier. Series of honeycomb ceramic catalyst carrier are made from the material of cordierite through the process of extrusion. Specification for honeycomb ceramic catalyst carrier is 100-400 pores or cells per square inch. Honeycomb ceramic usually carries noble metal catalyst, e.g. platinum, rhodium, or palladium to clean waste gas in industries, e.g. it can be formed the catalytic converter to purify tail gas applied in automobile industry.  When tail gas pass through catalytic converter, catalyst can enhance activities of CO, NOx and HC inside tail gas, converting them into CO2, H2O, N2, and O2 through selective oxidation-reduction reaction. Therefore, tail gas can be purified.
