Local rocks rich in alunite mineral, field of application in oxidation catalysts Heterogeneous as a support factor

الملخص

Local alunite-bearing rocks have been employed as supporting materials in
heterogeneous oxidation of acrolein to acrylic acid over bismuth molybdate catalyst .
The applied technique has a great activity compared with the previous studies.
Infrared spectroscopy and nuclear magnetic resonance were performed to identify the
final products. Powder x-ray diffraction and thermogravemetric analysis were used
to study the reduction and reoxidation processes of the catalyest.
