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: 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

In the reactor organic substance, or substances, respectively, are introduced which react with practically all the residual ammonia without this affecting the acrylonitrile yield. It is preferable that the organic substance should be methanol which is introduced in the reactor at temperatures bellow the points of its carbonization.

Abstract: By the method, the ammonium sulphate formed during themanufacture of acrylonitrile is considerably reduced or completelyeliminated by means of direct amoxydation (reaction betweenammonia and oxygen) of propylene/propane, ammonia and oxygencontaining gas, e.g. air, on a catalytic fluid bed. Methanol isintroduced in the upper part of the reactor used at a point whereit reacts with the residual ammonia without this affecting theacrylonituile yield. The methanol is introduced in the reactor ata temperature under the point of its selfignition. When catalystis used for fluid bed, poor in oxygen, ogygen conraining gas inintroduced in the reaction at a distance from 20.32 and 30.48 cmfrom the place of methanol feeding.
