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 substan tially reduced.
Méthode pour augmenter le rendement en produit d'ammoxydation, consistant à introduire une alimentation dans un réacteur, à faire passer un flux gazeux oxygéné contenant au moins une fraction de charges inertes, à faire passer un flux d'oxygène pratiquement pur dans le réacteur, et à réduire le débit du flux gazeux oxygéné tout en augmentant le débit dudit flux d'oxygène pratiquement pur; le débit total du flux d'oxygène provenant du flux gazeux oxygéné et du flux d'oxygène pratiquement pur est maintenu à une valeur permettant d'obtenir le produit d'ammoxydation tout en réduisant sensiblement le débit de charges inertes passant dans le réacteur.
