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. |
