Cerium Zirconium Lanthanum Yttrium Solid Rare Earth Catalyst

Cerium Zirconium Lanthanum Yttrium Solid Rare Earth Catalyst

       Automotive exhaust emission is a major cause of air pollution. Rare earth elements possess 4f orbitals without full electron occupancy and lanthanide contraction. This characteristic results in their unique chemical properties when they are used as catalysts or catalytic components.Rare earth elements possess 4f orbitals without full electron occupancy and lanthanide contraction. This characteristic results in their unique chemical properties when they are used as catalysts or catalytic components.​ Three-way catalyst (TWC) which can eliminate CO, HC (hydrocarbons), and NOx simultaneously has been used to control exhaust emissions.

【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
