Two commercial nanocrystal *BEA zeolites CP811 (P1) and CP814E (P2) with same total Si/Al ratio (Si/Al_total = 12) but different textural properties, were desilicated using different alkaline treatment; classical in presence of NaOH alone, or incorporated with a pore directing agent. P1 was desilicated by NaOH alone, and NaOH + TPABr, while P2 was desilicated in presence of NaOH + TBAOH. A synthesized microcrystal *BEA zeolite with Si/Al total ratio of 36, was also desilicated with NaOH alone, NaOH + TPABr, and NaOH + TBAOH. All parent and desilicated zeolites were transformed into bifunctional catalysts by platinum loading and were tested in the hydroisomerization of n-C₁₀. P1 zeolite was impregnated with different Pt contents to insure maximum activity and selectivity towards isomers products. It has been seen that the improvement of the textural properties by desilication using the different pore directing agents, was not always the cause behind an increase or decrease in the activity and selectivity of the catalyst, but rather was more the location of the Pt particles and their predicted distance from the acidic sites. However, the presence of an interplay between the inter- and intracrystalline mesopores, with the additional parameter of Pt-H⁺ distance, serve better as combined characteristics behind the final activity and selectivity.

 使用不同的碱处理对两种具有相同的总Si / Al比（Si / Al_总数= 12）但结构特性不同的商品化* BEA纳米沸石CP811（P1）和CP814E（P2）进行了脱硅处理；单独使用NaOH或与孔隙导向剂结合使用时的经典方法。P1仅通过NaOH和NaOH + TPABr进行脱硅，而P2在NaOH + TBAOH的存在下进行脱硅。合成的Si / Al总比为36的微晶* BEA沸石也单独用NaOH，NaOH + TPABr和NaOH + TBAOH脱硅。通过负载铂将所有母体和脱硅酸盐的沸石转化为双功能催化剂，并在n -C ₁₀的加氢异构化中进行了测试。。P1沸石浸渍有不同的Pt含量，以确保最大的活性和对异构体产物的选择性。已经发现，通过使用不同的孔隙导向剂进行的脱硅作用来改善质地性能，并非总是导致催化剂的活性和选择性增加或降低的原因，而是更多的是Pt颗粒和Pt颗粒的位置。它们与酸性位置的预测距离。然而，晶间介孔和晶内介孔之间相互作用的存在，加上Pt-H ⁺距离的附加参数，可以更好地作为最终活性和选择性背后的综合特征。
