Cerium Nitrate

CERIUM SALTS & COMPOUNDS

    CERIUM NITRATE ( Ce(NO3)3)
CERIUM NITRATE

Cerium Nitrate is highly water soluble crystalline Cerium source for uses compatible with nitrates and lower (acidic) pH.

 

    CERIUM NITRATE SYNONYMS

  • Nitric acid cerium salt, Cerous nitrate, Cerium trinitrate, Cerium(3+) cationtrinitrate
  • Molecular Formula: Ce(NO3)3
  • Molecular Weight: 326.13

If fired at high temperature, it forms cerium oxide, which can be used as the raw material of cerium oxide based polishing powder and many glass polishing powder manufacturers use this process. Cerium is used in FCC catalysts because it substantially increases the activity and stability of the zeolite, which is the most active component in the catalysts.

This comparison at a constant catalyst-to-oil ratio (C/O) shows the typical changes through applying rare earth exchange to zeolites:

  • The activity is substantially increased, which results in much higher liquefied petroleum gas (LPG) and, particularly, gasoline yield, mainly at the cost of bottoms.
  • Theolefinicity of the LPG fraction is decreased.
  • Owing to the lower olefinicity, gasoline olefinicity and octanes will also decrease
  • Coke and delta coke are increased.

 

No other elements have yet been found to increase zeolite activity and stability as efficiently and cost-effectively as lanthanum and cerium.
