应用X-射线相分析并结合催化剂的活性评价,考查了乙苯脱氢催化剂的相组成及相转变。实验结果表明,K_2Fe_(22)O_(34)·n/mK_2O与催化活性之间无显著联系。本文讨论了催化剂活性相的可能状态与转化,初步认为K_2Fe_(22)O_(34)·n/mK_2O不大可能是有效活性相。
X-ray phase analysis was used in combination with the activity evaluation of the catalyst to examine the phase composition and phase transition of the ethylbenzene dehydrogenation catalyst. The experimental results show that there is no significant relationship between K 2 Fe 22 O 34 (34) · n / mK 2 O and catalytic activity. In this paper, we discuss the possible state and transformation of the active phase of the catalyst. It is preliminarily believed that K 2 Fe 22 O 34 (34) · n / mK 2 O is unlikely to be an effective active phase.
