摘要

The loss mechanisms and the loss kinetics of MoO₃ on MoO₃/Al₂O₃ and MoO₃/SiO₂ catalysts are studied in this paper. It is found that the loss of MoO₃ is caused by the reaction of molybdenum species on the surface of the catalysts with water. The loss kinetics of MoO₃ are the same on both catalysts and can be expressed as r=k VC_a^3.5. But the loss of MoO₃ is smaller on MoO₃/Al₂O₃ than on MoO₃/SiO ₂, which is related to the strength of interactions between molybdenum trioxide and the supports.
