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.

Abstract: The method consists in the introduction of additional quantity of oxygen-containing gas, preferably air, in the absence of any oxygen-saturated compounds in the upper part of the fluidized bed reactor which reacts with at last part of the unreacted ammonia, in order to reduce the content of the available, unreacted ammonia in the waste reactor fluid.
