Method of making mixed metal oxide catalysts for ammoxidation and/or oxidation of lower alkane hydrocarbons

摘要

The present invention comprises a method for preparing a mixed oxide catalyst for use in producing acrylonitrile or methacrylonitrile from propane or isobutene by ammoxidation in a gaseous phase via methods of heating or calcining precursor solid mixture to obtain mixed metal oxide catalyst compositions that exhibit catalytic activity.
