乙苯脱氢催化剂中铁钾化合物形成过程的穆斯堡尔谱研究

Msbauer study on the formation process of Fe-K composition in iron-based catalyst for dehydrogenation of ethylbenzene

用穆斯堡尔谱学的方法研究了乙苯脱氢含钾铁系催化剂中活性相的前身 ,铁钾尖晶石结构的形成过程。着重讨论了催化剂的组分和制备条件与产物的关系 ,为新型工业催化剂的研制和筛选提供了重要的依据。

Fe-K spinel structure is the predecessor of active phase of potassium promoted iron-based catalyst for dehydrogenation of ethylbenzene. Mssbauer spectroscopy has been used to study the formation process of Fe-K spinel structure which depends on the catalyst composition and preparing condition. The results may prove useful for production of industrial catalyst.
