考察了α－Ｆｅ２Ｏ３在ＭＣＭ－４１，ＨＭＳ和ＫＩＴ－１三类介孔分子筛上的分散情况，以及介孔分子筛负载氧化铁催化剂的乙苯脱氢性能．实验结果表明，α－Ｆｅ２Ｏ３能有效地分散在介孔分子筛的表面上，其分散阈值远高于其他载体，由此大大提高了乙苯脱氢反应的活性．钾的引入对该类负载催化剂会产生不利影响
The dispersion of α-Fe2O3 on MCM-41, HMS and KIT-1 mesoporous mesoporous molecular sieves and the dehydrogenation of ethylbenzene on mesoporous molecular sieve supported iron oxide catalysts were investigated. The experimental results show that the α-Fe2O3 can be effectively dispersed on the surface of mesoporous molecular sieves, and the dispersion threshold is much higher than that of other supports, thus greatly increasing the activity of ethylbenzene dehydrogenation reaction. The introduction of potassium adversely affects this type of supported catalyst
