摘　　要：在Mo-Fe-K-Ce金属氧化物体系中添加适量的ZnO,可使脱氢活性相(KFe11O17)的形成温度降低50℃以上,从而使得乙苯脱氢生成苯乙烯的反应温度下降了5～18℃。新研制的Mo-Fe-K-Ce-Zn系催化剂具有较佳的机械强度、耐水性能和稳定性,可以在工业装置上应用。It was found that addition of just the right moment ZnO to Mo-Fe-K-Ce metal oxide system can lower the formative temperature of the active phase for dehydrogenation (KFe _(11)O _(17)),by more than 50 ℃,and thus decrease the ethylbenzene dehydrogenation temperature by 5～18 ℃.This new type Mo-Fe-K-Ce-Zn catalyst for dehydrogenation have fine mechanical strength,property against moisture and stability for ethylbenzene dehydrogen-ation reaction.It will be applied to industrial equipment.
