Title:
IMPROVED PHOSPHORUS/VANADIUM OXIDATION CATALYST
Document Type and Number:
Japanese Patent JP2577831
Kind Code:
B2
Abstract:
PURPOSE: To provide an improved phosphorus/vanadium oxidation catalyst used for partial oxidation of hydrocarbons such as n-butane.
CONSTITUTION: The catalyst contg. phosphorus, vanadium, zinc and lithium mixed oxides is prepared by adding a molybdenum compd. modifier at a Mo/V molar ratio of 0.005-0.025:1 during the digestion of the reduced vanadium compd. by concn. phosphoric acid. The addition of Mo products a catalyst which is very stable, more active and lives longer than the unmodified catalyst.
