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.

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 H2-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. © 2024 Elsevier B.V.

Abstract ：
To gain a profound understanding of the reaction pathway and the controlling step of residue oil slurry-phase hydrocracking over Fe2O3 catalyst, a six-lumped kinetic model was proposed and employed to acquire the kinetic rate constants based on each fraction yield obtained at 400 to 420 °C under initial H2 pressures of 8 to 10 MPa for 1 to 3 h. The optimal kinetic rate constant for each step of vacuum residue (VR) conversion process was determined via Levenberg-Marquardt algorithm and the sum of squares error (SSE). The results reveal that VR converted into naphtha and diesel is dominant according to their kinetic rate constants, followed by the conversion of vacuum gas oil (VGO) to diesel, diesel to naphtha, and diesel to gas. Furthermore, the sensitivity analysis confirms a strong agreement between the predicted and experimental values. The combination of kinetic rate constants and activation energy illustrates that the gas product primarily originates from naphtha. Additionally, the higher H2 pressure effectively mitigates coke deposition by restricting the aggregation of polycyclic aromatics, as evidenced by the increase in the reaction activation energy for the conversion of VR to coke and the analysis of the used catalyst. © 2024 Elsevier Ltd

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 ：
The catalytic dehydration of glycerol to acrolein offers a sustainable route for efficiently utilizing low-cost and renewable bioglycerol. This work deeply explores glycerol dehydration to acrolein over ZSM-5 zeolite catalysts with various pore structures and aluminum distributions. The results reveal that glycerol conversion is enhanced through the construction of a mesoporous structure and the increase in Br & oslash;nsted acid sites of the catalysts, but acrolein selectivity is not directly related to these factors. Further characterizations, density functional theory calculation, kinetic study, and reaction mechanism analysis demonstrate that the richest Alsingle sites in the zeolite framework and the least Alpair sites in the straight and sinusoidal channels can prevent the generated acrolein from adsorbing on adjacent Al sites. This allows acrolein to immediately escape from the catalyst surface, reducing side reactions and enhancing its selectivity. Therefore, the synergistic between the mesoporous structure and more Alsingle sites in the ZSM-5 zeolite framework promotes acrolein yield. Additionally, a descriptor phi, reflecting the amount of Alsingle sites and the external specific surface area of the ZSM-5 zeolite, is first proposed to more clearly elucidate the structure-performance relationship. This study provides a new perspective for understanding the mechanism of catalytic dehydration of glycerol to acrolein, guiding the development of highly efficient catalysts. It is significant for the sustainable development of the biodiesel and acrolein production industry.

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.
