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.
