These diffusion constraints can be mitigated by introducing secondary porosity and reducing the crystallite size. This study investigates the effect of the silica content (varied via the SiO2/Al2O3 molar ratio) on these parameters. The physicochemical properties of the synthesized samples were characterized by XRD, SEM, 29Si MAS NMR, NH3-TPD, and some other methods. Increasing the SiO2/Al2O3 ratio was shown to reduce the size of primary nanocrystals and generate a well-developed mesoporous structure. At SiO2/Al2O3 ratios ≥ 0.3, the extent of silicon incorporation and the concentration of acid sites reach a maximum, while a decrease in crystallinity was observed. The most developed hierarchical porous structure, featuring an external surface area of 67 m2/g and a mesopore volume of 0.19 cm3/g, was achieved at a SiO2/Al2O3 ratio of 0.1. In the hydroisomerization of n-hexadecane, the sample synthesized with a SiO2/Al2O3 ratio of 0.3—which exhibited an optimal combination of high acidity and small nanocrystal size—achieved the highest conversion and i-C16 selectivity. Therefore, fine-tuning the silica content is an effective strategy for the targeted design of high-performance hydroisomerization catalysts.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"65 10","pages":"1203 - 1214"},"PeriodicalIF":1.1,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145957985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a more economical synthesis method using hexamethylenediamine (HDA) as an affordable SDA. A series of high-crystallinity zeolite samples (SiO2/Al2O3 = 160–200) were synthesized hydrothermally. After loading with 0.5 wt % Pt, their physicochemical properties and catalytic performance were evaluated in the hydroisomerization of n-hexadecane at 3.0 MPa. The initial alkali content in the reaction gel was identified as a critical parameter controlling crystallization selectivity, crystal morphology, and crystallinity. The sample synthesized with low alkali content exhibited the highest performance, achieving 90% n-hexadecane conversion at 320°C with a yield of desired isomers up to 62%. This demonstrates the high potential of HDA for crystallizing selective ZSM-48 and for preparing promising catalysts for the hydroisomerization of higher n-paraffins.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"65 10","pages":"1193 - 1202"},"PeriodicalIF":1.1,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145958007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In some cases, to reflect more completely recent advances in the development of metal-containing zeolite catalysts for dehydrogenation of lower alkanes, examples concerning ethane dehydrogenation, which is performed under harsher conditions are also presented, as well as oxidative dehydrogenation of lower alkanes with CO2. Particular attention is paid to studies of structure–property and synthesis–structure relationships.
