Activated Alumina catalyst used in exhaust gas treatment
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.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 |
| Color | white |
| Chemistry composition | La2O3 | 4±1% |
| Al2O3 | ≥95% |
| Physical property | D50(μm) | 3-6 |

【Product features】
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 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.
【Packing】 25kgs/poly-drum ,500kgs/pallet
