通过溶胶-凝胶法制备了系列介孔NiAl催化剂,研究了不同还原温度下Ni含量为 20%(x)的介孔NiAl(20NA)催化剂在 1,6-己二醇(HDO)催化氨化合成 1,6-己二胺(HMDA)中的催化性能.利用N2 吸附-脱附、H2-TPR、CO-TPD、XRD、SAXS、XPS、SEM、TEM、ICP-OES等方法对试样进行表征.实验结果表明,低温还原后的 20NA催化剂表面金属Ni0 粒径较小,具有较高的HDO转化率.440℃还原的 20NA催化剂在温和反应温度(190℃)下,HMDA最高产率可达30.9%,除低聚物外的高附加值产物的总选择性高达 94.7%(x),HDO转换频率与文献报道的贵金属Ru基催化剂相当.通过调节还原温度可有效控制20NA催化剂表面金属Ni0 位点的纳米尺寸.

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.

Abstract ：
Controllable synthesis of hierarchical zeolites from natural aluminosilicate minerals is considered an efficient and eco-friendly approach for the production of high-performance zeolites, but its synthesis mechanism is still obscure. Herein, we take the synthesis of a single-crystalline hierarchical NaA zeolite using submolten salt depolymerized kaolin (SMS-K) as the sole source of silicon and aluminum via a mesoscale reorganization strategy as an example to elucidate the reorganization process. Comprehensive morphological and structural analyses reveal that sodium-rich voids in SMS-K facilitate concurrent assembly both within the interior and at the interface of the amorphous gel, leading to the formation of numerous nanoparticles with short-range order which assemble into single-crystal nanocube NaA zeolites with intracrystalline mesopores. By harnessing confinement effects, SMS-K modulates the growth of nanoparticle sizes and enhances the intimate interconnection of nanocubes, thereby yielding NaA zeolite aggregates that exhibit hierarchical porosity, encompassing micro-, meso-, and macropores. This study offers the potential for designing and precisely controlling the fabrication of hierarchical zeolites derived from natural minerals.

Abstract ：
Propylene is the second most important chemicals in the petrochemical industry. Propane dehydrogenation as the on -purpose propylene production route, has attracted much attentions due to great success in the exploitation of shale gas. Recently, Pt@zeolite is proven to the most promising catalyst for propane dehydrogenation, because Pt clusters encapsulated in zeolite channel show high resistance to Pt particles sintering. However, the micropore of zeolite imposes severe diffusion limitation of propylene, and thus the coke formation easily takes place which leads to a fast deactivation. Herein, we report efficient Pt/Zn-MFIhierarchical catalysts for PDH with auxiliary mesopore for accelerating mass transfer, and these Pt/Zn-MFIhierarchical exhibit not only high thermal stability but also excellent resistance to coking. The Pt/Zn-MFIhierarchical catalyst is obtained by an introduction of Pt species into the hierarchically porous Zn-MFI that is prepared from one-step hydrothermal synthesis. The formed Pt-Zn clusters are exclusively located in the micropore of MFIhierarchical, and the migrating of Pt-Zn clusters is largely prevented under the harsh reaction conditions. Mesopores in MFIhierarchical greatly enhances the diffusion rate of propylene, which significantly alleviates the coke formation arising from polymerization of propylene. The most efficient Pt/Zn-MFI-120hierarchical catalyst delivers propane conversion of around 46 % and propylene selectivity of above 98 %. This catalyst undergoes a slow loss of activity with a deactivation rate kd of as low as 0.005 h-1, and its catalytic performance can be fully restored via a simple calcination.

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 ：
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
