Abstract ：
A low-cost and process-intensified synthesis approach of SSZ-35 zeolite via a seed-assisted method is presented. This approach involves the development of a relatively inexpensive template and the application of seeds to minimize crystallization time and template consumption. Herein, N-Ethyl, N-methyl 2,6-cis-dimethylpiperidinium hydroxide (EMDMPOH) is selected as a template to synthesize SSZ-35 zeolite, and a simplified and optimized scheme for the preparation of such a template is proposed. Specially, the high-purity EMDMPOH is prepared by a sequential alkylation of 2,6-dimethylpiperidine with iodoethane and iodomethane, followed by ion exchange. By employing a seed-assisted strategy, the synthesis process of SSZ-35 zeolite is intensified, resulting in a significant reduction in crystallization time from 7 d to 75 h. Systematic characterizations reveal that the synthesized SSZ-35 zeolite has smaller crystals and larger specific surface area in comparison with the reference sample, leading to enhanced selectivity in n-octane hydroisomerization. Moreover, the cost accounting analysis shows a notable decrease in the synthesis cost of SSZ-35 zeolite by using the synthesis route that combines the simplified process for preparing the template and the reduced amount of template.

Abstract ：
In order to gain insight into the influence of SiO2 support particle size on the vacuum residue (VR) slurry-phase hydrocracking performance of Fe-based catalysts, a series of FeZn/SiO2 catalysts with varying SiO2 particle sizes were prepared. Characterization results show that the surface area and pore volume of the FeZn/SiO2 catalysts increase with the reduction of SiO2 particle sizes. The metals Fe and Zn species on FeZn/SiO2-S catalyst are more readily reducible via H2-TPR analysis. Notably, FeZn/SiO2-S catalyst presents higher metal dispersion and a greater degree of sulfurization compared to the other catalysts by XRD and XPS. Hydrocracking results demonstrate that the FeZn/SiO2-S catalyst achieves the lowest coke and gas yields (11.9 wt% and 0.4 wt%), respectively, and the highest VR conversion among these catalysts. The superior performance of the FeZn/SiO2-S catalyst in VR slurry-phase hydrocracking is ascribed to its enhanced hydrogenation activity, deriving from the higher dispersion and sulfurization of metals species. This suppresses the aggregation of polycyclic aromatic hydrocarbons in VR and the over-cracking of intermediate products. Additionally, the increased mesopore associated with smaller SiO2 particles facilitates to the diffusion of large VR molecules, further promoting the hydrocracking reaction.

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 ：
Natural rectorite modified by the hydrothermal method was employed to prepare a catalyst for the slurry-phase hydrocracking of vacuum residue (VR). The influence of hydrothermal treatment on the properties of rectorite and the performance of the corresponding catalyst was examined. Hydrothermal treatment of the rectorite led to the formation of Fe3O4, as evidenced by H-2-TPR analysis. XPS results indicate that the hydrothermal treatment of rectorite can intensify the sulfidation process of Mo species supported on it, possibly due to modifications in the surface properties of the rectorite. Comparative slurry-phase hydrocracking tests showed that the catalyst supported on hydrothermally treated rectorite exhibited significantly higher VR conversion, higher liquid product yield, and higher yields of gasoline and diesel fractions, but lower gas yield compared to the catalyst supported on untreated rectorite. This is ascribed to the high hydrogenation activity of the catalyst supported on hydrothermally treated rectorite, which effectively suppresses the over-cracking reactions of intermediate products that would otherwise produce gas, illustrating the process intensification achieved through hydrothermal treatment.

Abstract ：
NaY zeolites are synthesized using submolten salt depolymerized natural perlite mineral as the main silica and alumina sources in a 0.94 L stirred crystallizer. Effects of alkalinity ranging from 0.38 to 0.55 ( n (Na 2 O)/ n (SiO 2 )) on the relative crystallinity, textural properties and crystallization kinetics were investigated. The results show that alkalinity exerts a nonmonotonic in fluence on the relative crystallinity and textural properties, which exhibit a maximum at the alkalinity of 0.43. The nucleation kinetics are studied by fitting the experimental data of relative crystallinity with the Gualtieri model. It is shown that the nucleation rate constant increases with increasing alkalinity, while the duration period of nucleation decreases with increasing alkalinity. For n (Na 2 O)/ n (SiO 2 ) ratios ranging from 0.38 to 0.55, the as -synthesized NaY zeolites exhibit narrower crystal size distributions with the increase in alkalinity. The growth rates determined from the variations of average crystal size with time are 51.09, 157.50, 46.17 and 24.75 nm $h -1 , respectively. It is found that the larger average crystal sizes at the alkalinity of 0.38 and 0.43 are attributed to the dominant role of crystal growth over nucleation. Furthermore, the combined action of prominent crystal growth and the longer duration periods of nucleation at the alkalinity of 0.38 and 0.43 results in broader crystal size distributions. The findings demonstrate that control of the properties of NaY zeolite and the crystallization kinetics can be achieved by conducting the crystallization process in an appropriate range of alkalinity of the reaction mixture.

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.
