Abstract: Redn. in the amt. of unreacted ammonia exiting the reactor in acrylonitrile mfr., comprises: (a) contacting with a fluid bed catalyst, in the lower portion of a fluid bed reactor, ammonia, O2 and a hydrocarbon comprising propylene or propane, to produce acrylonitrile; (b) feeding O2 free of any oxygenate cpds. into the upper portion of the fluid bed reactor, at a point where the additional O2 does not affect the reaction, but reacts with at least some of the unreacted ammonia; (c) cooling the reactor effluent contg. acrylonitrile by feeding into a water quench column; (d) removing unwanted impurities; and (e) recovering acrylonitrile from the quench column.
