Title:
ACTIVATION OF CATALYST
Document Type and Number:
Japanese Patent JP2559938
Kind Code:
B2
Abstract:
PURPOSE: To obtain a catalyst exhibiting good activity in the ammoxidation of propane by calcining a compsn. contg. the oxides of V and Sb to the temp. equal to or above the specified one, thereafter bringing it into contact with a liq. hydroxy compd., separating the liq. and executing drying.
CONSTITUTION: An activated Sv and V-contg. catalyst in oxide form having an atomic ratio of Sb:V in the range from 0.8 to 4 is produced. At this time, the compsn. contg. the V and Sb in oxide form is calcined at ≥750°C, and the calcined catalyst is brought into contact with a hydroxy compd, in liq. form selected from cyclohexanol, cyclopentanol, 1-8C monohydroxy, acyclic hydrocarbon and 2-4C dihydroxy, acyclic hydrocarbon. The compd. as a liq. is separated from the catalyst insofar as it is present beyond the amt. wetting the catalyst, and then, the catalyst is dried. As a result, the catalyst exhibiting good activity in the ammoxidation of propane can be obtd.
