ABSTRACT:
A supplementary catalyst for long term maintaining the activity of the fluidized bed catalysts for ammoxidation of propylene to produce acrylonitrile. Particularly, the present invention provides a supplementary catalyst for compensating for the loss of the fluidized bed catalyst caused by the volatilization of molybdenum and loss of fine particles during operation. By adopting the supplementary catalyst, the life-time of the fluidized bed catalysts for ammoxidation of propylene to produce acrylonitrile in fluidized bed reactors can be increased from 1-1.5 years to 4 or more than 4 years.
