COMPOSITIONAL INHOMOGENEITY AND LATTICE DYNAMICS IN THE M1 CATALYST – IMPLICATIONS CONCERNING ACTIVE SITES FOR PROPANE OXIDATION

摘要

Selective oxidation catalysis is used in production of roughly 25% of all important organic chemicals and intermediates used for making consumer and industrial products [1]. Significant cost savings exist if processes using light alkene feeds can be replaced with new processes using the corresponding alkane feedstocks. The dominant catalyst candidate for selective oxidation and ammoxidation to produce acrylic acid and acrylonitrile, respectively, from propane is based on the multiphase MoVTeNbO complex oxide system [1-3]; the same system is also effective for selective oxidation of ethane to ethylene.
