摘要：

Molybdena/Al2O3 catalyst precursors have been prepared by impregnation from aqueous solution and by solid/solid wetting (spreading) in mixtures of MoO3 and Al2O3 in either humid or dry oxygen atmosphere. Thiophene HDS at atmospheric pressure was chosen as a test reaction. Those catalyst preparations which contained a surface heptamolybdate species in the oxide precursor state showed the highest HDS conversions. © 1990.
