Process for preparing fluidized bed catalyst for production of aromatic nitriles |
| abstract |
FLUIDIZED BED CATALYST HAVING AN ATOMIC RATIO OF V:CR:B OF 1:0.5-2.0:0.1-1.2, A TOTAL AMOUNT OF THEIR OXIDES CARRIED ON THE CATALYST BEING 20 TO 80% BY WEIGHT, BASED ON THE WEIGHT OF THE CATALYST AND CLOSED BULK DENSITY OF 0.85 TO 1.20 G./ML. IS PREPARED BY SPRAY-DRYING A SILICA SOL SLURRY CONTAINING A VANADIUM COMPOUND, A CHROMIUM COMPOUND AND A BORON COMPOUND ESPECIALLY PREPARED BY USING A DISSOLUTION AGENT FOR THE BORON COMPOUND, FOR EXAMPLE, A CIS-POLYHYDRIC ALCOHOL HAVING HYDROXYL GROUPS AT AN A- OR B-POSITION MUTUALLY OR AN A-HYDROXYCARBOXYLIC ACID, AT AN OUTLET TEMPERATURE OF A SPRAY-DRIER OF 85* TO 160*C. THE CATALYST IS USEFUL FOR THE PRODUCTION OF AROMATIC NITRILES BY FLUIDIZED BED METHOD. |
