High quality molecular sieve Activated Alumina Powder
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. Most catalysts in all of the above applications use noble,
platinum group metals as their active components.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.
(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|
The 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
(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.
