Cerium Zirconium Rare Earth Catalyst For Three Way Catalytic Converter Structure

Cerium zirconium solid solution of three-way catalytic converter Structure

The ternary converter (TWC) has always been the main emission control technology for light-duty gasoline vehicles. Combining TWC with an oxygen sensor-based closed-loop fuel delivery system can simultaneously convert three standard pollutants, HC, CO, and NOx generated during the fuel combustion process in spark ignition engines. Active catalytic materials are used as precious metals (for example, Pt, Pd) , Rh) and oxide-based inorganic promoters and thin coatings of carrier materials are present on the inner wall of the honeycomb substrate. The substrate usually provides a large number of parallel flow channels to allow sufficient contact area between the exhaust gas and the active catalytic material without excessive pressure loss.


【Application】

(1) 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】

【Product features】

(1) high temperature resistance and high aging ability: using cerium oxide and zirconia solid solution as the matrix, some additives (lanthanum oxide, yttrium oxide, praseodymium oxide, neodymium oxide) are added to replace the elements, which improves the high-temperature anti-aging ability of the products.
(2) Excellent oxygen storage and release capacity: the product has higher oxygen storage and release rate, faster oxygen storage and release rate and lower light off temperature
(3) Moderate particle size distribution: the medium diameter of the material is controlled to be 2.5-3.5 μ m by using air grinding and precise grading technology, and the particle size distribution is narrow, which improves the coating quality and reduces the peeling off rate.
(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
