  • Oxygen addition to reduce inerts in an acrylonitrile reactor
    Patent number: 5883281
    Abstract: A process for increasing the yield of an ammoxidation product by passing a feed into a reactor, passing an oxygen-containing gas stream containing at least a portion of inerts into the reactor, passing a substantially pure oxygen stream into the reactor, and reducing the flow of the oxygen-containing gas stream while increasing the flow of said substantially pure oxygen stream, wherein the total rate of flow of oxygen from the oxygen-containing gas stream and the substantially pure oxygen stream is maintained in an effective amount to produce the ammoxidation product such that the flow of said inerts passing into the reactor is substantially reduced.
