Mo/ZSM-5 type catalysts based on two ZSM-5 zeolites with comparable crystal morphology, shape and size, Si/Al in bulk (22–23), acidity and amount of Mo (~ 4.7 wt.%) but having a different (homogeneous and non-homogeneous) Al distribution in particles and different acid sites type distribution were investigated in methane dehydroaromatization. From the results follows that Mo is associated with both BAS and LAS in the samples with almost homogenous Al distribution (MoZSM-5/AH). In the case of both samples with non-homogenous Al distribution (MoZSM-5/BH and MoZSM-5/BNH₄) Mo preferably associates with BAS. Evidently lower activity and selectivity of Mo/ZSM-5/AH catalyst in methane transformation compared with Mo/ZSM-5/BH we attribute to the fact that from Mo species which interact with Lewis acid sites in sample ZSM-5/AH less active carburized species are formed as from the Mo associated with Brønsted sites in sample ZSM-5/BH.

Mo / ZSM-5型催化剂，基于两种ZSM-5沸石，具有可比的晶体形态，形状和大小，Si / Al体积（22-23），酸度和Mo量（〜4.7 wt。％），但具有不同的性质在甲烷脱氢芳构化过程中，研究了（均匀和不均匀）Al在颗粒中的分布以及不同酸位点类型的分布。从结果可以看出，Mo与样品中的BAS和LAS都具有几乎相同的Al分布（MoZSM-5 / AH）。对于两种均具有非均匀Al分布的样品（MoZSM-5 / BH和MoZSM-5 / BNH ₄）Mo优选与BAS关联。与Mo / ZSM-5 / BH相比，Mo / ZSM-5 / AH催化剂在甲烷转化中的活性和选择性明显较低，这归因于以下事实：与样品ZSM-5 / AH中的路易斯酸位相互作用的Mo物种的活性较低渗碳物质是由ZSM-5 / BH样品中与布朗斯台德位点相关的Mo形成的。
