Modified Alumina
From a view point of preventing air pollution caused by the
emission of these noxious compounds, it is required to render the
exhaust gases harmless by oxidizing carbon monoxide, hydrocarbons,
etc., in the exhaust gases and by reducing or decomposing the
nitrogen oxides before the exhaust gases are released into the open
air. The above-mentioned oxidation and reduction reactions can be
accomplished by using a catalyst.Following the success in mobile
engine applications, catalyst technologies were introduced for
stationary applications, for the control of volatile organic
compounds (VOC) and NOx emissions.
【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.
【Specification】
| TYPE | AC-100 |

| Al2O3 | ≥95% |
| Physical property | D50(μm) | 3-6 |

【Product features】
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
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.
