Catalytic oxidation of olefin over oxide catalysts containing molybdenum: II. Variation of kinetic parameters of propylene oxidation with composition of cobalt-molybdenum binary oxide catalysts

摘要: Abstract Variation of catalytic property Co3O4MoO3 binary oxide with its composition was investigated in the oxidation propylene. Some kinetic data such as specific activity, apparent activation energy, and reaction orders propylene oxygen were determined, varying molybdenum concentration 10 atomic % difference each. Addition a small amount trioxide to cobalt, caused remarkable changes these parameters. On contrary, addition cobalt did not seriously affect trioxide. These variations parameters seem correspond variation product distribution Active species for acetone formation by means X-ray diffraction infrared absorption.
