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&Keyword Cite

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.

Investigation of the effective diffusion coefficient of nitrogen gas using high-resolution 3D X-ray computed tomography images of nuclear-grade graphite IG-110 SCIE

Abstract&Keyword Cite

Abstract :

Nuclear-grade graphite IG-110, an isotropic fine-grained solid material, is widely studied for its applications in high-temperature gas-cooled reactors (HTGRs). Gas diffusion is a crucial parameter in understanding mass transport phenomena in nuclear graphite during the dehumidification and operational processes of HTGRs. Despite the importance of gas diffusion modeling, limited numerical frameworks have been developed to predict diffusion coefficients within the microstructure of nuclear-grade graphite. In this study, geometric models of nuclear graphite were obtained using X-ray computed tomography, and the dimensionless diffusivity of nitrogen was calculated using the lattice Boltzmann method (LBM) and electrical conduction simulations. The computational model was validated against experimental data, showing a close alignment between the numerical approach and the experimental results. Additionally, the experiment found that gas diffusion within nuclear graphite logically decreases with increasing gas pressure and remains unaffected by confining pressure. These theoretical findings are useful for understanding water transport in nuclear graphite during the dehumidification process.

Abstract&Keyword Cite

Abstract :

The substitution of air with O2/CO2 atmosphere is a promising solution for CO2 recirculation during coal gasification. However, a comprehensive understanding on the formation mechanism of PAHs and soot under different conditions is necessary to reduce their emissions. This work presents simulation results of a two-stage entrained flow coal gasifier in a 250 MW industrial-scale plant using detailed chemistry. The influences of reductor temperature (1000-1200 degrees C) and coal types (bituminous coal, sub-bituminous coal, and lignite) on PAHs and soot formations from the coal volatiles in the reductor were simulated through a detailed chemical kinetic model under air and O2/CO2 atmospheres. Results show that 2- and 3-ring aromatics are main PAHs products. Rising temperature has inhibitory effects on PAHs formation, especially for lignite. The O2/CO2 condition reduces the PAHs yield compared with the air condition. Rate of production analysis reveals that conversion of major PAHs occurs mainly between PAHs and their radicals. Vinyl-naphthyl radical and indenyl radical play an important role in the acenaphthylene conversion. In addition, soot production increases with a higher temperature under both air and O2/CO2 conditions. The O2/CO2 condition effectively suppressed soot production through a weaker HACA surface growth route than the air condition. lignite produces the least soot, and sub-bituminous coal produces the most. This study deeply reveals the formation mechanisms of PAHs and soot in a two-stage entrained flow gasifier through detailed chemical kinetic modeling, giving an insight into the complex PAHs and soot formations to assess the design and the operating condition of gasifier with O2/CO2 injection.

Unraveling the structure-performance relationship of foam reactor with hierarchical pore structure for dry reforming of methane reaction SCIE
期刊论文 | 2025 , 389 | FUEL
Abstract&Keyword Cite

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&Keyword Cite

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.

The synergistic effect between Ru single-atomic sites and nanoclusters during catalytic hydrotreatment of fast pyrolysis liquids from lignocellulosic biomass EI

Abstract&Keyword Cite

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&Keyword Cite

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 :

Metal foam flow field shows great potential for next-generation proton exchange membrane (PEM) fuel cell of high power density due to its well-connected pore structure, high thermal and electrical conductivity. However, the complicated pore structure makes it a challenge for water management. To tackle this issue, a novel design of metal foam flow field with hierarchical pore structure was proposed. Based on lattice Boltzmann method (LBM), the structure-performance relationship between hierarchical pore structure and water discharge capability of flow field was explored by using breakthrough time. Furthermore, an optimal hierarchical pore structure for metal foam flow field that shows superior water discharge capability was obtained. Compared with metal foam with uniform coarse pore structure, breakthrough time can be reduced roughly by 17.6% in the one with optimal hierarchical pore structures. This finding provides a theoretical foundation and technical guidance for developing metal foam flow field.

Abstract&Keyword Cite

Abstract :

Catalytic hydrotreatment is one of the promising routes for upgrading pyrolysis liquids (PLs) to intermediates that can be co-fed with vacuum gas oil for FCC refinery. Among all the factors, catalysts are always crucial in catalytic hydrotreatment of PLs as hydrogenation and repolymerization reactions occur in parallel. Therefore, catalysts with sufficient hydrogenation activity are generally required to enhance the hydrogenation reaction and to inhibit the repolymerization reaction of the thermally liable compounds in PLs. Among all noble metal catalysts tested, Ru/C catalysts showed a better performance than other catalysts in terms of the oil yield and deoxygenation level. However, a clear repolymerization was observed during catalytic hydrotreatment of PLs using Ru/C catalysts, especially during mild hydrotreatment, thus there is still ample room for their activity improvement. Here, a series of Ru-based catalysts supported on nitrogen-doped carbon materials (NC) and activated carbon (AC) were prepared. The catalytic performance was evaluated for hydrotreatment of PLs in a batch autoclave (250 degrees C, 8 MPa H2, 4 h for mild hydrotreatment; 340 degrees C, 6 MPa H2, 4 h for deep hydrotreatment). The Ru catalyst supported on nitrogen-doped carbon materials, obtained by the polyol reduction method with polyvinylpyrrolidone (PVP) as the protective agent (Ru/NC (PVP)), showed a better performance (in terms of product oil properties) than the other catalysts investigated in this work, due to a good distribution of the ruthenium nanoparticles. For mild hydrotreatment the H/C ratio, O/C ratio and MCRT value were 1.42, 0.37 and 9.9 wt%, respectively. For deep hydrotreatment the H/C ratio, O/C ratio and MCRT value were 1.26, 0.16 and 4.6 wt%. The comparison with results published earlier for other hydrotreatment catalysts is satisfactory but also shows room for further improvement. GC-MS and 1H NMR results showed that the contents of thermal liable components like aldehydes (16.7 %), ketones (24.3 %) and sugars (4.0 %) in PLs were quantitatively converted under mild hydrotreatment, while phenols and alkanes significantly increased from 35.9 %, 0 % to 49.1 %, 35.3 %, respectively, especially for deep hydrotreatment compared with PLs feed. The catalyst characterization revealed that Ru/NC (PVP) with the most uniform dispersion and the smallest average particle size (1.5 nm), rendered the best performance. These findings indicate that Ru/NC (PVP) catalyst is a promising candidate for the catalytic hydrotreatment of PLs.
