Abstract ：
Supported noble metal cluster catalysts are typically operated under severe conditions involving switching between reducing and oxidizing atmospheres, causing irreversible transformation of the catalyst structure and thereby leading to permanent deactivation. We discovered that various platinum (Pt) precursors spontaneously disperse in a germanium-MFI (Ge-MFI) zeolite, which opposes the Ostwald ripening phenomenon, producing self-regenerating Pt/Ge-MFI catalysts for propane dehydrogenation. These catalysts reversibly switch between Pt clusters and Pt single atoms in response to reducing reaction and oxidizing regeneration conditions. This environmental adaptability allows them to completely self-regenerate over 110 reaction and regeneration cycles in propane dehydrogenation, and they exhibited unprecedented sintering resistance when exposed to air at 800 degrees C for 10 days. Such spontaneous metal dispersion in a Ge-MFI zeolite is a robust and versatile methodology for fabricating various rhodium, ruthenium, iridium, and palladium cluster catalysts.

Abstract ：
The C2-O cleavage of furanic ring is the crucial step in selective hydrogenation of furfuryl alcohol (FOL) to 1,5pentanediol (1,5-PDO). In this study, reduced mixed Ni-Co-Al metal oxide catalysts with rich oxygen vacancy (Ov) and different Co/Ni molar ratios were prepared through intercalation modification of Co-based hydrotalcite by ammonium citrate (CA), followed by calcination and reduction. The catalytic performance exhibited that a quantitative conversion of FOL with 44.4 % yield and 8.2 mmol1,5-PDO & sdot;gcat -1 & sdot;h- 1 productivity of 1,5-PDO were achieved by using Co2Ni1Al1Ox-CA(0.1) (molar ratio of Co:Ni = 2:1; molar concentration ratio of CA:Na2CO3 = 0.1) under optimal conditions. The stability test showed that Co2Ni1Al1Ox-CA(0.1) consistently rendered above 40 % yield of 1,5-PDO in seven consecutive cycles. Catalyst characterizations were carried out using a series of techniques including XPS, EPR, O2-TPD, etc. The results demonstrate that the addition of CA effectively altered the surface molar ratios of Co2+/(Co2++Co3+), thereby regulating the Ov content of the obtained catalysts. The CoO-Ov sites in the catalyst might enhance the adsorption of FOL by eta 1-(O)-alcoholic model, which weakened C2O bond on the furanic ring of FOL. Besides, the H2-TPD anslysis confirmed that the enhanced spillover of hydrogen from Ni0 onto CoO-Ov site, thereby promoting the cleavage of the C2-O bond in FOL and subsequent hydrogenation of enol intermediates. In addition, the DFT calculations imply that FOL adsorption on CoO-Ov site by eta 1-(O)-alcoholic model was significantly favorable than that on pristine CoO sites (-1.68 eV versus -1.55 eV). Consequently, this study has substantiated the crucial role played by CoO-Ov in the reaction pathway leading to 1,5-PDO formation via FOL, proposing a viable scheme for designing catalysts based on transition metals and elucidating their underlying reaction mechanism.

Abstract ：
This study proposes integrating the catalytic distillation dehydrogenation system with a solid oxide fuel cell (SOFC) system to recover and reuse the waste heat from the SOFC exhaust gases. The research focuses on a 25 kW SOFC system and categorizes potential system layouts into three types based on the final use of the exhaust gas. Through a comprehensive analysis from energy, environmental, economic and exergy (4E) perspectives, the results show that while the SOFC stack dominates the energy and economic factors, leading to consistent performance across similar system layouts, the thermodynamic irreversibility during system operation is influenced by exergy destruction and exergy loss. Using a multi-criteria evaluation approach, the optimal integration scheme, where the final exhaust gas is utilized for preheating air, was identified when all four indicators were equally weighted. The results indicate that the optimal system achieves a thermal efficiency of 46.97% and improves system energy efficiency by 52.59%. Furthermore, compared to the initial non-integrated system, the integrated system reduces environmental carbon emissions by 58.56%, increases economic efficiency by 36.64% and reduces exergy losses by 94.11%, highlighting the advantages of system integration. More importantly, the integrated system has a competitive levelized cost of electricity (LCOE) of 0.134 $/kWh, demonstrating its potential for a wide range of applications, from small-scale to large industrial processes.

Abstract ：
Given the rising demand for cyclohexanol in the nylon industry and the escalating issues of high production costs and potential environmental harm in traditional cyclohexanol production, developing a safe, environmentally friendly, and cost-effective process for producing cyclohexanol from cyclohexene is crucial. In addition, the different composition of intermediates will significantly affect the economy of each reaction unit. Therefore, this study proposed a novel reactive distillation process involving esterification, transesterification, and hydrolysis. Three reactive distillation processes of 1000 t/a capacity of cyclohexanol production with different purity intermediates were designed and optimized using a sequential iterative algorithm to minimize the total annual cost, which amounted to 422116.65 $/a. Furthermore, the energy consumption and environmental emissions were compared after optimization. By comparing the influence of various purity intermediates on each process unit, it was qualitatively determined that higher purity requirements did not necessarily yield superior results. Finally, to quantify the influence of each variable on economic performance of whole process, response surface method was performed using central composite design for minimum total annual cost objectives with a 3.25 % error between model and simulation. This study aims to guide the development of a comprehensive, costeffective, and efficient reactive distillation process for cyclohexanol production.

Abstract ：
To cope with small production quantities of specialized chemicals, modular production plants have gained increasing attention in recent years. Zero-gravity distillation (ZGD) is a small-scale distillation process, which offers high separation efficiency, proving advantageous for modularizing processes. In this research, the study of ZGD process intensification is conducted. A ZGD experimental setup was established and the separation of ethanol/water mixtures was chosen as an example to investigate the effects of metal foam material, liquid filling rate, and PPI of metal foam on the separation performance, which was quantified by height equivalent to a theoretical plate (HETP). The results reveal that under constant feed volume (50 ml) and the mole fraction of ethanol (0.2), employing 40 PPI copper foam and 100 % liquid filling rate results in HETP of 5.56 cm for ZGD unit, demonstrating superior separation performance. Subsequently, an optimization strategy adopting sandwich internal structure with ordered hierarchical meta foam is proposed to further intensify the separation process. In contrast to the case of employing 40 PPI copper foam and liquid filling rate of 100 %, the optimization strategy can further reduce HETP by approximately 18.17 %, being 4.55 cm. This finding provides a theoretical foundation and technical guidance for developing zero-gravity distillation technology.

Abstract ：
Dry reforming of methane (DRM), which is a viable approach for carbon capture and utilization, is notably inclined towards carbon deposition due to the formation of cold spots, causing catalyst rapid deactivation, thereby limiting its industrial application. In order to prevent catalyst coking, it is imperative to improve the heat and mass transfer processes in DRM reactors. A foam reactor with hierarchical pore structure was proposed in this work, which is composed of fine and coarse pores and avoids contact thermal resistance due to the contact of foam structures with different pore sizes. Based on lattice Boltzmann model, this work investigated the impact of hierarchical pore structure on the heat and mass transfer, as well as DRM reaction in Ni/Al2O3 based foam reactors. The findings suggest an optimal overall heat transfer coefficient with the variation of dcoarse/dfine under equal pumping power. Furthermore, it reveals a synergistic mechanism between the heat and mass transfer processes, identifying an optimal hierarchical pore structure which, compared to uniform fine and coarse pore structures, facilitates an enhancement in reaction performance by 14.1 % and 13.0 %, respectively. This work provides a theoretical foundation and technical direction for the design of foam reactors.

Abstract ：
Catalytic hydrotreatment is a promising technique to upgrade pyrolysis liquids (PLs) with undesired properties into intermediate that can be co-processed with vacuum gas oil in FCC refinery. Highly active catalysts are key in such a process. In this study, a ruthenium-based catalyst possessing both single-atomic and nanocluster sites supported on hierarchically porous nitrogen-doped carbon (Ru1+NPs/HPNC) was prepared by a two-step alcohol reduction method. Catalytic performance was evaluated for both model compound vanillin (VL) and PLs in a batch autoclave. The model compound study showed that Ru1+NPs/HPNC exhibited excellent intrinsic activity in VL hydrogenation, with a TOF of 26.9 s−1, which is approximately 3 times higher than that of Ru1/HPNC (8.4 s−1) and RuNPs/HPNC (8.8 s−1), and 6 times that of Ru/AC (4.2 s−1). Catalytic hydrotreatment of PLs indicated that Ru1+NPs/HPNC possessed the best activity regarding to the highest H/C ratio (mild hydrotreatment: 1.33; deep hydrotreatment: 1.29) and the lowest TG residue (mild hydrotreatment: 14.4 wt%; deep hydrotreatment: 6.5 wt%) of the product oils. To obtain understanding of the synergistic effect between single-atoms and nanoclusters, the adsorption of VL and H2 on the catalyst was examined by ATR-FTIR and DFT calculations. The results revealed that VL is preferentially adsorbed and activated on the single-atomic sites, while the H2 is preferentially dissociated on the nanocluster sites. Based on these findings, a plausible mechanism is proposed. This study offers new ideas for developing better-performing catalysts for catalytic hydrotreatment of PLs. © 2025 Elsevier Ltd

Abstract ：
Capsules with designable chemical and textural structures provide a universal and versatile platform for enzyme immobilization. Herein, a capsular biocatalyst (TpBD CP@Lactate dehydrogenase@Silica capsules, TLS capsules) was developed by entrapping enzyme within the wall of conjugated polymer (CP)/silica hybrid capsules. The porous wall of TLS capsules provided sufficient adsorption sites for a high enzyme loading capacity of 102.79 mg g-1, as well as abundant and shorter substrate transfer pathways, resulting in catalytic efficiency of 133.0 % that of free LDH. TLS capsules achieved an optimal balance between substrate enrichment and diffusion at a 30 mmol L-1 Na2SiO3 solution concentration, resulting in a 14 % increase in catalytic activity. Furthermore, the mineralized silica layer provided suitable enzyme-carrier interactions, ensuring the structural stability of the enzyme under extreme conditions. TLS capsules maintained over 80.47 % relative activity after eight cycles. Our work broadens the scope for developing and applying enzyme immobilization platforms.

Abstract ：
Hydrogen enriched natural gas represents an important pathway for achieving low-carbon and green transformation in the domestic gas sector. However, the flame tends to become unstable when a large proportion of hydrogen is blended. To investigate the flame instability mechanisms, a model for the diffusion combustion of hydrogen-enriched natural gas in porous media has been established based on a simplified reaction mechanism. Model validation through temperature and oxygen mole fraction comparisons demonstrated maximum and average errors of 4.1 % and 1.5 %, respectively. These error ranges were confirmed to be within acceptable accuracy limits, indicating that the established numerical model effectively represents the actual combustion processes. Additionally, a novel flashback identification method was proposed based on flashback classification. Numerical analyses were conducted to investigate the mechanisms of flashback occurrence during the combustion process of hydrogen-enriched natural gas under critical hydrogen blending ratios. The results indicate that the flashback mode within the burner is characterized as boundary layer flashback. Consequently, the peak temperature judgment method can be effectively employed to detect the occurrence of flashback within the burner. When the hydrogen blending ratio reaches 40 %, some reactions will occur within the porous medium, leading to a sharp increase in OH radical concentrations, which ultimately results in flashback phenomena. Additionally, the transition in combustion modes can cause insufficient oxygen replenishment in certain areas, thereby causing a dramatic increase in CO production. This study provides theoretical guidance and technical support for the application and promotion of hydrogen enriched natural gas in household gas appliances. © 2025

Abstract ：
In our previous study, a novel triple-column heterogeneous azeotropic distillation with decanter and condenser (TCHAD-SDC) method was developed to separate the pyridine wastewater by recovering pyridine homologues. The separating dilemma of pressure-swing situation and the inefficiency of extractive distillation were thoroughly explored. By investigating the intrinsic thermodynamic principle, the optimal entrainer was determined. However, in these complicated systems with multiple azeotropes and homologues, the conflicting factors arise between the solvent recycle path and the homologues' separation. The mutually exclusive situation poses challenges in determining the optimal process sequence. Based on the antagonistic relationship, an applicable strategy is proposed to address the homologue-azeotropic coexisting systems. This strategy comprehensively considers the impact of the compositional differences and similar properties in the homologues. Therefore, various triple-column heterogeneous azeotropic distillation (TCHAD) schemes are developed. Subsequently, each sequence is optimized globally and intensified by heat integration. The results indicate that there is a compromise between these two factors, and the second TCHAD scheme with 3-methylpyridine distilled first leads to the highest economic benefit as expected. The optimal sequence reduces the total annual cost and energy consumption by 34.3 % and 41.6 % respectively compared with the previous research. The general strategy could provide for other complex industrial systems involving multiple azeotropes and homologues.
