Product Description

Alumina-supported Rare Earth −Zr Complex Oxide

 

    [Applied Field]

  • Catalyst for cleaning exhaust gases of automotives and motorcycles
  • Cleaning of industrial organic exhaust gases and indoor air
  • Catalyst for nature gases combustion
  • Catalytic decomposition in fluidized-bed in oil refining industry

    [Product Properties]

  • Being carried by γ-Al2O3 can accelerate the dispersing of rare earth-Zr complex oxide in the carrier and keep the stability of the specific surface area at high temperature. Therefore, it improves the activity and lifetime of the catalyst materials
  • The crushing and mixing of γ-Al2O3 and rare-earth-Zr compound oxide can improve the mixture uniformity.
  • Slurring the products when using, it is convenient for the users.

    [Instruction]

  • Making the product to 35% slurry with water, adding 1% poly-vinyl alcohol, then adjusting the slurry to PH=2~3 with nitric acid.
  • The second spreading, if needed, should be performed after the coatings prepared by the first spreading have been solidified and dried.
