摘要
应用穆斯堡尔谱学和X -射线衍射技术 ,研究了钾含量对乙苯脱氢铁钾系催化剂中KFe11O17物相形成的影响。发现催化剂中氧化钾质量分数为 1 0 %左右时对形成KFe11O17物相较有利 ,而KFe11O17物相的存在有利于提高催化剂的性能。
The effect of K 2O on the forming of KFe 11 O 17 in catalyst for the ethylbenzene dehydrogenation was studied by Mossbauer spectroscopy and X-ray diffraction methods.The results showed that the catalyst containing about 10% of K 2O could easily form KFe 11 O 17 .The KFe 11 O 17 with spinel structure was useful for increasing the activity of catalyst used in ethylbenzene dehydrogenation to styrene.
