Abstract
A PROCESS FOR THE SUBSTANTIAL OR COMPLETE ELIMINATION OF AMMONIUM SULFATE GENERATED DURING THE PRODUCTION OF ACRYLONITRILE BY THE DIRECT AMMOXIDATION OF PROPLENE/PROPANE, AMMONIA AND AN OXYGEN CONTAINING GAS (E.G. AIR) OVER A FLUID BED CATALYST WHEREIN THE IMPROVEMENT COMPRISES INTRODUCING AN ORGANIC COMPOUND(S) INTO SAID REACTOR AT A LOCATION WHERE THE COMPOUND(S) REACTS WITH SUBSTANTIALLY ALL OF THE EXCESS AMMONIA WITHOUT AFFECTING THE ACRYLONITRILE YIELD. PREFERABLY, THE ORGANIC COMPOUND IS METHANOL WHICH IS INTRODUCED INTO THE REACTOR AT BELOW ITS COKING TEMPERATURE.
