In this work, Nano-sized ZSM-5 zeolites were successfully synthesized with a modified seed-induced method by using a short-chain tetrabutylammonium fluoride (TBAF) as a crystal inhibitor. The effects of TBAF/SiO2 molar ratios and SiO2/Al2O3 ratios on morphologies, textural properties, acidity and catalytic performance in MTP reaction were systematically investigated. The results confirmed that highly crystalline ZSM-5 nanocrystals with abundant mesopores were synthesized because of the amphipathy of TBAF. More interestingly, weak acidity could be tuned efficiently via varying TBAF/SiO2 ratio at the similar strong acidity, while both the weak and strong acidity were changed by adjusting SiO2/Al2O3 ratio. Moreover, the prepared nano-sized ZSM-5 catalyst (Z5-167-10) showed an excellent MTP reaction performance with long catalytic lifetime (120 h) and high propylene selectivity (44.9%) benefiting from the unique mesoporous structure and acid properties, which delayed the coke formation.</div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"32 4","pages":"1485 - 1496"},"PeriodicalIF":3.2,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145164899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oxidative-adsorptive desulfurization (OADS) performance of the coupled desulfurizer was investigated using a dodecane solution containing dibenzothiophene as the model oil.
