“…319 Besides site accessibility and acidity of the zeolite, the location of the Pt species and the degree of intimacy between metal and Brønsted acid sites has also a significant impact on the hydroisomerization performance of Pt/H-zeolites. [320][321][322] Moreover, the size and orientation of Pt crystallites has been found to heavily influence the n-alkane hydroisomerization behaviour of bifunctional Pt/H-zeolites.…”

“…[348] These results were also obtained by the second group who obtained an improved crystallinity and thermal stability in the synthesis of hollow beta zeolite nanocrystals. [345] Tetrapropylammonium hydroxide/ bromide (TPAOH, TPABr) was used by multiple groups, [349][350][351] as is the case for tetrabutylammonium hydroxide/bromide (TBAOH, TBABr) [352] and cetyltrimethylammonium hydroxide/bromide (CTAOH, CTABr). [353][354][355] Although there is a subtle difference in structure, the overall outcome after use of these mesoporogens was similar.…”

Zeolites are highly crystalline aluminosilicates with welldefined pores that are constructed of SiO 2 and AlO 4 tetrahedra. These tetrahedra can be linked together in different unique ways to form various materials with a specific topology. [1] According to the International Zeolite Association (IZA), more than 250 different topologies, which are all assigned with a three-letter code, have been identified. [2] The micropores in zeolites are typically constructed from 8, 10, or 12 tetrahedral atoms

“…Simultaneously, the shortened residence time of the intermediates in the mesopores diminishes consecutive reactions, such as cracking, enhancing selectivity to isomers. The works of [76][77][78] have shown that the creation of mesopores in Pt/ZSM-5, Pt/mordenite, and Pt/β catalysts improved their activity in n-alkane hydroisomerization due to the lifted intracrystalline diffusion limitations in the zeolite pore system.…”

Hierarchical AlSBA-15–zeolite materials were utilized as a supports for preparing hydroisomerization catalysts. Detailed consideration was given to: (i) the effect of the zeolite type introduced into AlSBA-15–zeolite composites (where zeolite is β, mordenite or ZSM-5) as well as (ii) the promotion effect of Pd addition. The composites showed higher activity in isomerization as compared to Pt/AlSBA-15. The enhanced isomerization efficiency were explained by the appropriate metallic and acidic function as well as suitable transport properties. The modification of the hydrogenating function by Pd incorporation increases the hydroisomerization efficiency of Pt-Pd/AlSBA-15–β catalyst. Over bimetallic Pt-Pd/AlSBA-15–β, the high yields of isomers (68 wt%) with respect to 50 wt% for a control catalyst. The most promising Pt-Pd/AlSBA-15–β catalyst allows to improve research octane number from 0 to the 74 value.
