ABSTRACT:
Acrylonitrile is produced by passing a gaseous mixture comprising propylene, molecular oxygen and ammonia upwardly through a fluidized bed comprising particles of a highly-active acrylonitrile catalyst in physical admixture with particles of a composite consisting essentially of antimony oxide and silica. The use of the antimony oxide-silica composite moderates the effect of the highly-active acrylonitrile catalyst reducing its activity sufficiently to enable the use of longer residence times, but without reducing the acrylonitrile selectivity of the catalyst.
