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 composition 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 C-8 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 ：
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 ：
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 ：
In order to develop a high-efficiency iron oxide catalyst for the slurry-phase hydrocracking of poor heavy oil, the mesoporous iron oxide was successfully synthesized by using the waste wood powder as a template, and the influence of alkali concentration in the resulting solution on crystal phase, morphology and pore structure of the synthesized samples was investigated. The crystal phase of the synthesized iron oxide transfers from alpha-Fe2O3 to gamma-Fe2O3, and their crystal sizes gradually decrease with an increase of alkali concentration based on the XRD and HRTEM results. Additionally, the iron oxide with mesoporous structure, larger surface area and pore volume is obtained at the higher concentration of alkali in solution confirmed by N2 adsorption-desorption analysis. The assessment result of the iron oxide catalyst employed in the slurry-phase hydrocracking of vacuum residue (VR) illustrates that the yields of gasoline and diesel distillates obtained over Fe-O-B20, Fe-O-B24 and Fe-O-B30 cata-lysts are higher compared with those over Fe-O-B2 and Fe-O-B14 catalysts, it can be attributed that more exposure Fe active sites derived from their larger surface area and pore volume availably improve the catalyst hydroge-nation activity, which can inhibit the over-cracking reaction of intermediate products and the condensation of polycyclic aromatic hydrocarbon in VR to enhance the yields of gasoline and diesel distillates.

Abstract ：
Aiming at improving reaction selectivity of zeolite Beta-catalyzed isomerization of normal alkane, we reported a facile but efficient route to prepare the Beta@SBA-15 composite supports with low surface diffusion barriers in isomers formation from normal alkane. Microporous Beta zeolite and mesoporous SBA-15 zeolite were physically mixed and milled by high-energy planetary ball-mill. The addition of SBA-15 and milling, which have little effect on the acid properties of Beta zeolites, disaggregate the Beta particles and anchor the Beta nanocrystals on the surface of SBA-15 mesostructure. The apparent diffusivities of 2-methyl pentane measured by zero-length column method increased by 50%. n-Hexane isomerization tests show that the Pt/Beta@SBA-15 catalysts exhibit much higher selectivity to isomers, especially the dibranched isomers and lower selectivity to cracking reaction, owning to the reduced transport limitation of composite supports.

Abstract ：
A sustainable defect-engineering strategy for the dealumination of Y zeolite is described. This strategy includes the green synthesis of a well-crystallized Y zeolite with point defects arising from the incorporation of Fe atoms by using Fe-containing perlite and the subsequent preparation of ultra-stable Y (USY) zeolite by efficient steaming dealumination. The systematic characterizations verify that Fe atoms originally existing in the perlite are incorporated into the as-synthesized Y zeolite and function as point defects, leading to the distortion of framework Al. The step-by-step investigation of dealumination process shows that vacancies are formed by the extraction of framework Fe in ammonium exchange, and the framework dealumination is promoted under the combined effect of the distorted framework Al and the formed vacancies during steaming treatment. The resulting USY zeolite owns excellent features in (hydro)thermal stability, pore structure and acid property, and exhibits outstanding catalytic performance in the cracking of n-octane and 1,3,5-triisopropylbenzene.

Abstract ：
The understanding of reaction mechanism is the key to develop the highly efficient catalyst. The introduction of Pt on SO42-/ZrO2 surface greatly improves its catalytic stability in n-butane hydroisomerization, but the function of Pt is still in controversy. The introduction of Pt on sulfated zirconia surface only promotes the hydrogenation of coke precursor and slows catalyst deactivation during n-butane hydroisomerization, but has no effect on the initial conversion rate of n-butane and selectivity to isobutane. H2-TPR and H2-TPD investigations reveal that Pt functions via hydrogen spillover mechanism, rather than classical bifunctional "metal-acid" catalysis mechanism. Our findings provide a new perspective for the rational design and synthesis of "metal-acid" bifunctional catalysts for alkane isomerization.
