Tetrapropylammonium hydroxide was employed as both extrusion promoter and template to prepare shaped precursors. Subsequently, a series of binder-free ZSM-5 zeolites with adjustable SiO₂/Al₂O₃ ratios (SARs) from 25 to 130 were successfully synthesized via a facile steam-assisted crystallization process with minimal water consumption. XRD, XRF, SEM, N₂ physisorption, Py-IR, NH₃-TPD and TGA were employed to investigate the physicochemical properties of the as-obtained ZSM-5. It was found that, compared to binder-containing ZSM-5 zeolite, the binder-free zeolite exhibited high crystallinity, well-developed porosity and suitable acidic properties. In addition, the acid density, acid strength and acid distribution of binder-free ZSM-5 could be tuned by regulating SAR. Compared with the traditional binder-containing zeolite (NKZ5-40), the binder-free zeolite (Z5-40) prepared by this method demonstrated significantly superior performance in the n-hexane cracking: Z5-40 maintained 98.5% conversion over 500 min, which was 15% longer than that of NKZ5-40. Its yield of light olefins remained at 50.1%, much higher than the latter (34.8%), while the coke deposition rate was only 1.78 mg·gcat^− 1·h^− 1, approximately one-third of that of NKZ5-40. This method eliminates the use of organic extrusion promoters during the shaping process and cuts water usage, thereby conserving water resources and simplifying post-treatment. These features contribute to a more environmentally benign synthetic route, and this work establishes a foundation for future studies on extending the method to other zeolite frameworks and scaling it up for practical industrial use.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"33 4","pages":"1107 - 1117"},"PeriodicalIF":3.0,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782111","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 objective was to determine the effect of operating conditions on the efficiency of sulphur-removal as well as to support the experimental results by the use of Computational Fluid Dynamics (CFD) to analyse the internal flow and mixing patterns. The synthesis of catalysts was done via wet impregnation, and the catalysts were characterised using X-ray diffraction (XRD), N ₂ adsorptiondesorption analysis, NH 3 -TPD, and UV-Vis diffuse reflectance spectroscopy; the iron loading was determined using ICP-OES. Sulphur removal was systematically investigated with regard to the temperature (40–80 ^o C), reaction time (40–100 min), and the stirring speed (300–700 rpm). Within the ranges of temperature, contact time, and stirring speed, the removal of sulphur rose with temperature, length of contact time, and stirring speed. The highest reported sulphur-removal efficiency was 95.45 per cent at 80 ^o C, 100 min, and 700 rpm. The CFD findings showed that the increase in desulfurization performance was in line with the experimentally observed increase in the hydrodynamic behaviour and mixing at high stirring speeds. The results indicate that Fe-modified Beta zeolite is a potential catalyst to be used in photocatalytic desulfurization of diesel under relatively mild operating conditions, which is an alternative approach to deep sulphur removal less harsh than hydrodesulfurization.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"33 4","pages":"1093 - 1106"},"PeriodicalIF":3.0,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148783462","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}
