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 ：
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 ：
Designing efficient adsorbents for the deep removal of refractory dibenzothiophene (DBT) from fuel oil is vital for addressing environmental issues such as acid rain. Herein, zinc gluconate and urea-derived porous carbons SF-ZnNC-T (T represents the carbonization temperature) were synthesized without solvents. Through a temperature-controlled process of 'melting the zinc gluconate and urea mixture, forming H-bonded polymers, and carbonizing the polymers,' the optimal carbon, SF-ZnNC-900, was obtained with a large surface area (2280 m2 g−1), highly dispersed Zn sites, and hierarchical pore structures. Consequently, SF-ZnNC-900 demonstrated significantly higher DBT adsorption capacity of 43.2 mg S g−1, compared to just 4.3 mg S g−1 for the precursor. It also demonstrated good reusability, fast adsorption rate, and the ability for ultra-deep desulfurization. The superior DBT adsorption performance resulted from the evaporation of residual zinc species, which generated abundant mesopores that facilitated DBT transformation, as well as the formation of Zn-Nx sites that strengthened the host-guest interaction (ΔE = −1.466 eV). The solvent-free synthesized highly dispersed Zn-doped carbon shows great potential for producing sulfur-free fuel oil and for designing metal-loaded carbon adsorbents. © 2024 Institute of Process Engineering, Chinese Academy of Sciences

Abstract ：
Heavy metal contamination in water threatens human health and ecological security, necessitating efficient and sustainable remediation technologies. Adsorption is a widely used method due to its cost-effectiveness, high selectivity, and ease of operation. Among various adsorbents, conjugated microporous polymers (CMPs) have shown great potential for heavy metal removal, benefiting from their pi-conjugated structures, high surface area, tunable pore sizes, and strong metal ion interactions. However, challenges remain in synthesis and material properties. Extensive postsynthetic modifications may introduce structural complexity and compromise adsorption performance, while excessive functionalization can lead to pore blockage, reducing available adsorption sites. Additionally, inadequate distribution or low grafting density of chelating groups may weaken metal ion binding. Further challenges include enhancing selectivity, developing eco-friendly regeneration methods, improving stability in complex environments, and achieving large-scale production. Addressing these issues requires optimizing synthetic strategies, precisely incorporating functional groups, and improving pore structure control. This review summarizes recent advances in CMP-based heavy metal adsorption, discusses adsorption mechanisms and structural optimization, and identifies future research directions to advance their practical application in water purification.

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 ：
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 ：
Conjugated micro-mesoporous poly(aniline)s (CMPAs) synthesized through Buchwald-Hartwig coupling represent a cutting-edge material platform for selective sequestration of Hg (II) but suffer from moderate porosities and constrained availability of adsorption sites. Herein, we show a salt strategy for fine-tuning the porosity and Hg (II) adsorption performance of a series of S, N dual heteroatom functionalized CMPAs (CMPA-SN). The salt of NaF with appropriate dosage results in strikingly improved surface areas from 26 to 735 m2/g and intensified Hg (II) adsorption capacity from 311 mg/g to 649 mg/g. Moreover, CMPA-SN exhibits an efficient adsorption rate (h = 1250 mg/g/min) and excellent affinity with high Kd as high as 1.24 x 106 mL/g. We successfully correlate the adsorption capacity and surface area, and reveal the synergistic electron-sharing mechanism from N-containing ligands and in-situ decorated S heteroatoms, with 67.6 %/32.4 % contributions and Delta Eads = -0.419 eV/Delta Eads = -0.487 eV adsorption energy.

Abstract ：
This work underscores the critical importance of enhancing the mass transfer performance of catalyst particles for the production of n-butyl levulinate (BL) from levulinic acid (LA). The lattice Boltzmann method was proposed to investigate the relationship between pore structure and mass transfer, thereby guiding the rational design of high-performance catalyst. Furthermore, a novel catalyst regulation strategy was introduced, utilizing UiO-66 as a template to fabricate a series of catalysts, UiOxD40H160-SO3H. This strategy allows for the regulation of the pore structure of resin catalysts over a broader range and successfully enhanced the mass transfer performance. Among the synthesized catalysts, the LA conversion efficiency with UiO0.4D40H160-SO3H under mild reaction conditions increased by an average of 18.1% compared to the previously reported best-performing Dowex 50Wx2 resin catalyst. These findings provide valuable new insights into the production of BL while also highlighting the potential of the proposed catalyst design strategy for industrial applications. © 2025 Elsevier Ltd

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 ：
With the increasing demand of cyclohexanol in nylon industry, it is significant to develop a safe, green and economical process to produce cyclohexanol. For this purpose, a novel reactive distillation process through cyclohexyl acetate transesterification with methanol was proposed in this work. The NKC-9 catalyst was preferred to establish the reaction kinetic model based on pseudo-homogeneous model. Seven reactive distillation experiments with pilot-scale for cyclohexanol synthesis were explored to prove feasibility of reactive distillation processes and accuracy of model by comparing simulated results, which ensured the establishment of the process simulation. Furthermore, three reactive distillation processes of cyclohexanol production were designed and optimized by the sequential iterative algorithm based on minimum total annual cost. After optimization of pressure and recycled stream flow, a novel double column of reactive and pressure-swing hybrid distillation process showed the minimized total annual cost per ton product, which was 170.90 $/kg. Finally, total annual cost of transesterification, hydrolysis and hydrogenation processes were compared, and transesterification process demonstrated economic advantage. This work would provide a guidance for cyclohexanol green production by reactive distillation through cyclohexyl acetate transesterification, while a whole, economical and atomic economical reactive distillation process of cyclohexanol production could be established in the future.
