Abstract: By the method the ammonium sulphate formed during themanufacture of acrylonitrile by direct ammoxidation (reactionbetween ammonia and oxygen) of propylene or propane, ammonia andogygen-containing gas, such as air on catalyst fluidized bedfitted in respective reactor, is eliminated to a great extent orcompletely. In the reactor organic substance, or substances,respectively, are introduced which react with practically all theresidual ammonia without this affecting the acrylonitrile yield.It is preferable that the organic substance should be methanolwhich is introduced in the reactor at temperatures bellow thepoints of its carbonization.20 claims

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: A process for the substantial reduction or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.

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.
