Dispersion of MoO3 on low specific surface area support α-Al2O3 was studied withBET, SEM, XPS, XRD and LRS. The dispersion capacity of MoO3 on α-Al2O3 obtained by XPS and XRD are 0.15gMoO3/100m2 α-Al2O3 surface for α-Al2O3 obtained by calcinating γ-Al2O3 at1300℃ and 1200℃ and 0. 17gMoO3/100m2 α-Al2O3 for γ-Al2O3 obtained by calcinating γ-Al2O3at 1100℃.
- Low specific surface support,
- Spontaneous dispersion,
- Dispersion capacity
