Activated Alumina for automobile exhaust AC-100
Activated Alumina Powder is manufactured for water adsorption and
filtration applications by adsorbing impurities from the
surrounding environment. Activated alumina powder can be used in a
wide range of applications including the production of chemicals,
pharmaceuticals, and in static or dynamic dehydration applications.
This activated alumina offers a high adsorption capacity for both
static and dynamic adsorption processes.
The exhaust gases emitted from internal combustion engines usually
contain hydrocarbons, carbon monoxide, carbonyl compounds, etc.,
resulting from partial or incomplete combustion of fuels, and
nitrogen oxides produced by the reaction between oxygen and
nitrogen gases contained in the air used for the combustion of
fuels at elevated temperatures
【Application】
(1) Purification and catalysis of automobile and motorcycle exhaust
gas;
(2) Industrial organic waste gas purification and indoor air
purification;
(3) Natural gas combustion catalysis.
(4) Fluid catalytic cracking in oil refining industry.

【Product features】
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.
The second coat, which may comprise a top coat overlying the first
coat, contains a co-formed (e.g., co-precipitated) rare earth
oxide-zirconia support on which a first rhodium catalytic component
is dispersed, and a second activated alumina support having a
second platinum catalytic component dispersed thereon.
(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
products.
(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.
