Modified Alumina for automobile exhaust AC-100
Following the adoption of the CAA and the resulting vehicle
emission standards, oxidation catalysts have been commercialized in
the USA in the mid-1970s (first commercial application in model
year 1975 cars) to control emissions of CO and HC from spark
ignited (SI) gasoline engine applications. Three-way catalyst
technology, introduced in the 1980s, made it also possible to
control NOx emissions from SI engines at levels that are
significantly lower than NOx emissions from diesel engines.
Finally, in the 1990s, oxidation catalysts have been introduced to
diesel fueled cars in Europe, as well as to heavy-duty diesel bus
and (to a limited scale) truck engines in the USA. Since as early
as the 1970s, diesel catalysts have also been used in some
occupational environments, such as underground mining. Most
catalysts in all of the above applications use noble, platinum
group metals as their active components.
【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】
This 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.
The coat may also include a second rhodium catalytic component, and
optionally, a third platinum catalytic component, dispersed as an
activated alumina support. The present invention also provides a
method for treating engine exhaust gases by contacting the gases
under conversion conditions with the catalyst composition.
(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.
