Research Abstract:

Pure MoO3 and Cr2O3 and samples of the mixed oxide system Mo-O-Cr (1-15 wt.% Cr2O3) were prepared by mechanical mixing method, then calcined at 500 oC. The textural properties for the catalysts were investigated by analysis of N2 adsorption data at 77K. The results showed that the adsorption isotherms of N2 at 77K for all catalysts are mixed of types I and II. The specific surface areas were calculated by BET , V-t and V-αS methods. The analysis of the adsorption data proved that SBET , St and Sα are in good agreement . It has found that the specific surface area increased with adding Cr2O3 to MoO3. The specific surface area was gave maximum value for the catalysts containing 5wt.% and 10 wt.% Cr2O3. The pore diameter showed that the catalysts contain mesopores and micropores but its mainly mesoporous. The total pore areas volume VT increased with adding Cr2O3 and showed maxima for the catalysts containing 5wt.% and 10 wt.% Cr2O3.
