Abstract ：
A scrics of TS-1 zeolites were prepared by varying the addilions of seeds. The physicochemical properties of the synthesized TS-1 zeolites were systematically characterized by several analytical techniques, including X-ray diffraction, scanning electron microscopy, UV visiblc diffuser reflectance spectroscopy, Fourier transformed infrared spectroscopy, X-ray fluorescence spectroscopy and solid-statc nuclcar magnetie resonance spectroscopy. Morcovcr, the catalytic Performance and regeneration properties of the synthesized TS-1 zeolites in the one-step synthesis of ethylene glycol (EG) from ethylene was thoroughly evaluated. The results demonstrate that the addition of seeds can help improve the crystallinity of the synthesized samplcs. Spccifically, when the seeds mass fraction is 5%, the synthesized TS-1 zcolitc owns the highest Proportion of open framework titanium Ti—OH(HO—Si)3 species and strong Lewis aeid strength. When used in the one-step synthesis of EG from ethylene, this TS-1 zcolite exhibits excellcnt catalytic Performance, i. e., under the dosagc of catalyst of 0. 3 g, ethylene pressure of 2. 5 MPa, and temperaturc of 60 °C, H2()2 conversion rate is 91.1%, H202 utilization rate is 87.2%, and EG selectivity is 89. 8%. Furthermore, through investigating the regeneration properties of zeolites, it is found that thc synthesized optimal TS-1 zcolitc can be regenerated by calcination, and its catalytic Performance remains basically stablc aftcr bcing rcuscd for 5 times in thc one-step synthesis of EG from ethylene. © 2025 Editorial Office of Acta Petrolei Sinica.

Abstract ：
A seed-directed approach to synthesizing FeZSM-22 zeolite without organic structure directing agent(OSDA)was developed by using Fe-rich diatomite as all aluminum and iron sources.The FeZSM-22 zeolite with optimal crystallinity and purity can be obtained by systematically adjusting feed composi-tion and synthesis conditions.Characterizations show that FeZSM-22 zeolite synthesized with OSDA-free owns high crystallinity,obvious thin needle-shaped morphology and high Bronsted/Lewis acid ratio.Significantly,when used for n-octane hydroisomerization reaction,its derived catalyst exhibits the best catalytic performance reflected by the highest selectivity to C8 isomers compared to the two reference catalysts prepared based on a Fe-containing and a Fe-free ZSM-22 synthesized through an OSDA-directed route from natural diatomite and conventional chemicals,respectively.This work provides an alternative route to sustainably synthesizing heteroatomic zeolites with high performance.

Abstract ：
Synthesizing zeolites, which are important materials used in the petroleum and chemical industries, from natural aluminosilicate minerals has been qualitatively recognized as a greener approach compared to that from traditional Si- and Al-containing chemicals; however, studies on the quantitative environmental impacts are still lacking. Herein, life cycle assessment (LCA) and green metrics (atom economy and environmental factor) were employed to comparatively assess the life cycle environmental impacts of zeolites synthesized from chemicals and natural minerals at the industrial scale. The values of seven LCA impact categories and sensitivity analysis between them were thoroughly compared. The results showed that, for each category, the synthesis from natural minerals has lower environmental impacts to varying degrees than that from chemicals. Further efficiency analysis of zeolite manufacturing technologies by green metrics indicated that the synthesis from natural minerals outperforms that from chemicals in terms of the resource utilization rate. The quantitative results indicate that significant benefits stem from the replacement of raw materials from chemicals to natural minerals. This work may provide a basis for the future selection and upgrade of zeolite production processes. Life cycle assessment and green metrics were used to comparatively assess the synthesis of zeolites from natural minerals and chemicals in which the former exhibits a better balance between efficiency and environmental impacts than the latter.

Abstract ：
FAU型分子筛因其独特的孔道结构已成为化学工业中应用最广泛、用量最大的催化剂、催化剂载体及吸附剂之一.然而, FAU型分子筛单一的微孔孔道限制了客体分子的扩散,导致其性能严重下降.相比之下,等级孔FAU型分子筛具有微-介/大孔复合的多级孔道结构,能够促进大分子的扩散、提高活性位点的可接近性,进而改善其吸附和催化性能.目前,等级孔分子筛的制备方法主要包括“自下而上”的直接合成法和“自上而下”的后处理法.本文主要介绍了近年来等级孔X型和Y型分子筛制备方法的研究现状,重点总结了等级孔X型和Y型分子筛在吸附、催化等过程中的应用性能,并对等级孔FAU型分子筛的绿色化制备进行展望.

Abstract ：
FAU-type zeolites are an important class of porous aluminosilicate materials with a 3-dimiensional network of accessible micropores (0.74 nm), which primarily encompass X and Y zeolites. Typically, FAU zeolite with a framework SiO2/Al(2)O3 molar ratio between 2.0 and 3.0 is called X zeolite, and that is greater than 3.0 is classified as Y zeolite. Due to their distinctive structure and pore characteristics, FAU-type zeolites have emerged as one of the most widely used catalysts, catalyst carriers, and adsorbents in the chemical industry. However, the sole microporous channels of the conventional FAU-type zeolites not only make them difficult for the reactions involving bulky molecules to occur within pore channel, leading to insufficient contact between reactants with active sites of the zeolite, but also restrict the diffusion of product within the zeolite, thus affecting the activity and lifetime of the catalyst. Therefore, the key to improving the performance of FAU-type zeolites lies in alleviating the adverse effects of micropore diffusion on mass transfer. Introducing mesopores and/or macropores into microporous zeolites to construct hierarchical zeolites with a multi-modal pore structure is believed to be a promising approach. This modification not only can preserve the active sites from the microporous structure, but also significantly enhances the diffusion rate of guest molecules within the zeolites. Consequently, researchers have concentrated on the preparation and application of hierarchical zeolites. This article focuses on the current research status on the preparation of hierarchical X and Y zeolites based on "bottom-up" direct synthesis and "top-down" post-treatment methods. The direct synthesis method mainly comprises template and template-free methods. In terms of the template method, the pore structure of FAU zeolites can be tailored by altering the nature of the templating agent, synthesis conditions and so on. Differently, the template-free method enables the preparation of hierarchical FAU zeolites without the addition of any template. In particular, hierarchical X and Y zeolites have been successfully synthesized directly from natural aluminosilicate minerals without the use of organic templates, which not only reduces the synthesis cost of hierarchical zeolites from raw materials, but also contributes to environmental protection. This method provides a novel synthetic pathway for the preparation of hierarchical zeolites in a low-cost and green way. On the other hand, posttreatment method based on desilication and dealumination is the main method for the preparation of hierarchical Y zeolite, whereas few researchers have made use of post-treatment method to introduce meso/macroporous structures into X zeolite because of the poor chemical stability of X zeolite. In addition, the article introduces the application performance of hierarchical X and Y zeolites in adsorption, catalysis as well as other reaction processes. Despite the superior diffusion capabilities of hierarchical FAU-type zeolites, there are several problemsincluding high cost of organic templates and pollution emissions from the removal of template in the process of synthesizing hierarchical zeolites based on template method, limiting the industrial application of this method. As a result, designing cheap and recyclable templates is the key to realizing green and low-cost preparation of hierarchical FAU-type zeolite. Furthermore, post-treatment method cannot achieve the regulation of mesoporous size in hierarchical zeolites. Future research should deeply investigate the structureactivity relationship between the pore structure and reaction performance of hierarchical FAU-type zeolites, so as to further open pore channels, and enhance diffusion, thus promoting the development of hierarchical FAU-type zeolites in industrial applications.

Abstract ：
The development of sustainable techniques to produce high-performance zeolite is essential to achieve green production in industry.Herein,we report an eco-friendly route to synthesizing hierarchical Beta zeolite from kaolinite and recycled mother liquor.The results reveal that the unutilized species(such as silicon species and Na+)in mother liquor stayed in a stable concentration during eleven recycled experiments.Moreover,the syn-thesized Beta zeolites still have comparable physicochemical properties and catalytic performance in the esteri-fication of levulinic acid with ethanol over the initial zeolite although eleven recycled experiments.Life cycle assessment exhibits that the synthesis of Beta zeolite with recycled mother liquor can reduce global warming potential by 23％and resource depletion-water use by 36％compared to that without recycled mother liquor.This quantitatively demonstrates that the approach proposed in this work is really a sustainable one,extremely increasing the utilization efficiency of raw materials and decreasing the environmental burden.
