Rare Earth Elements<\/h3>\n

Rare earth elements possess a unique outer electron structure (4f), which allows them to serve as central atoms for coordination complexes, with coordination numbers ranging from 6 to 12. This variability in coordination numbers gives them “residual valency.” The 4f orbitals, with their seven available bonding sites, provide a “reserve chemical bond” or “residual valency,” a characteristic essential for catalysts.<\/p>\n

Performance of Rare Earth Catalysts<\/h3>\n

Rare earth elements not only have catalytic activity themselves but also act as additives or co-catalysts to enhance catalytic performance, especially in terms of aging resistance and anti-poisoning ability. Rare earth catalytic materials include molecular sieve rare earth catalysts, rare earth perovskite catalysts, cerium-zirconium solid solution catalysts, etc. These can be used for internal combustion engine exhaust purification, factory emissions and environmental purification, catalytic combustion, fuel cells, and low-value alkane utilization.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Cerium-Zirconium Solid Solution<\/h3>\n

Cerium-zirconium solid solution has excellent oxygen storage and release capabilities, making it a critical component of three-way catalysts (TWC). During catalytic reactions, it helps regulate the air-fuel ratio and serves as a catalyst support, effectively enhancing the catalytic activity and anti-sintering properties of precious metal catalysts. This can significantly increase the purification efficiency of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) in vehicle exhaust and factory emissions.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Rare earth-zirconium composite carrier coating materials have stable surface area and uniform particles, and they can be used in automotive exhaust purification, catalytic combustion of natural gas, factory waste gas treatment, indoor air purification, and catalytic cracking in oil refineries. These materials can reduce the amount of precious metals used without compromising purification efficiency, significantly lowering the production cost of catalytic purifiers for manufacturing enterprises.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Characteristics of Rare Earth-Zirconium Composite Carrier Coating Materials<\/h3>\n
    \n
  1. Scientifically optimized composition: The base is a cerium oxide and zirconium oxide solid solution, doped with some lanthanum oxide and yttrium oxide, resulting in optimal oxygen storage capacity and stable surface area.<\/li>\n
  2. Stable aged surface area: By controlling porosity and pore size, the surface area of the coating material is large and stable, enhancing the durability of the catalytic gas.<\/li>\n
  3. Fine and evenly distributed particles: The use of grinding and precision classification techniques ensures that the material does not settle during the coating process, improving product consistency.<\/li>\n<\/ol>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Rare earth oxygen storage materials have many advantages such as excellent oxygen storage capacity, faster oxygen storing\/releasing rate, lower firing point and higher hermal resistance stability. It also can promote the dispersing of precious metals, reducing the quantity of the precious metal, improving the catalytic activity and extending life time of the catalyst. This product can be applied in many areas, including automobile and motorcycle exhaust gas purification, catalytic combustion, industrial waste gas treatment, etc.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Coating material with RE-zirconium composite carrier has a perfect surface area stability, particles uniformity and other characteristics. It can be used in purification catalyst of vehicle exhaust gas, catalytic combustion of natural gas, the treatment of industrial waste gas, the purification of indoor air, as well as the oil refining industry in Sulfide catalytic cracking. RE-zirconium composite carrier coating materials can reduce the dosage without damaging purification effect, at the same time, significantly reducing relative enterprise costs.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
