Activated alumina is used as adsorbent
It is mainly used in tableware industry, jewelry industry, auto parts, optical lens, machine electrical accessories and other industries that need surface treatment.The calcination temperature of alumina polishing powder should be high, generally above 1600, so as to ensure that the product has good hardness.
【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】
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.
【Packing】 25kgs/poly-drum ,500kgs/pallet
