Activated alumina is used as adsorbent
It is mainly used in tableware industry, jewelry industry, auto
parts, optical lens, machine electrical accessories and other
industries that need surface treatment.The calcination temperature
of alumina polishing powder should be high, generally above 1600,
so as to ensure that the product has good hardness.
(1) Purification and catalysis of automobile and motorcycle exhaust
(2) Industrial organic waste gas purification and indoor air
(3) Natural gas combustion catalysis.
(4) Fluid catalytic cracking in oil refining industry.
|Aged BET(1000℃ 4h/m2·g-1)||>100|
A catalyst composition suitable for three-way conversion of
internal combustion engine, e.g., automobile gasoline engine,
exhaust gases includes a catalytic material disposed in two
discrete coats on a carrier.
The first coat includes a stabilized alumina support on which a
first platinum catalytic component is dispersed and bulk ceria, and
may also include bulk iron oxide, a metal oxide (such as bulk
nickel oxide) which is effective for the suppression of hydrogen
sulfide emissions, and one or both of baria and zirconia dispersed
throughout the first coat as a thermal stabilizer.
(1) High temperature resistance and high aging ability: the
modification of lanthanum oxide can inhibit the sintering of -Al2O3
and improve the high temperature anti-aging ability of the
(2) High solubility index and viscosity: the modified alumina is
easy to gel solution and has high viscosity, which can reduce or
not use aluminum sol, improve the coating performance and reduce
the shedding rate.
(3) The particle size distribution is moderate: the medium diameter
of the material is controlled to be 3-6 μ m and the particle size
distribution is narrow.
(4) Good product stability: advanced production technology and
production equipment, standardized management, to ensure the
stability of the product.
