    237-250页
    查看更多>>摘要：The performance of supported catalysts is significantly affected by the dispersion degree of the active components on the support.In this study,citric acid(CA)was used as a modifier to prepare Al2O3 supported Mn-Ce oxides(Mn-Ce/CA-Al2O3)by the impregnation-calcination method.The characteriza-tion results showed that adding citric acid enhanced the dispersion of Mn-Ce oxides on the support,rendering Mn-Ce/CA-Al2O3 with a larger specific surface area and abundant surface hydroxyl groups,thereby providing more reaction sites for catalytic ozonation.The Mn-Ce/CA-Al2O3 exhibited excellent catalytic ozonation performance in degrading Reactive Black 5(RB5)dye.It achieved nearly complete decolorization of RB5 within 60 min,with a COD removal efficiency of 60％,which was superior to the sole ozonation(30％).Furthermore,the Mn-Ce/CA-Al2O3 system demonstrated significant degradation of RB5 over a wide pH range of 3-11.Based on the XPS and EPR analysis results,a preliminary mechanism of catalytic ozonation over the Mn-Ce/CA-Al2O3 was proposed.The redox cycle of Mn3+/Mn4+and Ce3+/Ce4+effectively accelerated the electron transfer process,thus promoting the generation of reactive oxygen species(ROS)and improving the degradation of RB5.Meanwhile,the Mn-Ce/CA-Al2O3 exhibited superior catalytic stability and effective treatment capabilities for real dve wastewater.

    查看更多>>摘要：Proton exchange membrane(PEM)electrolyzer have attracted increasing attention from the industrial and researchers in recent years due to its excellent hydrogen production performance.Developing ac-curate models to predict their performance is crucial for promoting and accelerating the design and optimization of electrolysis systems.This work developed a Koopman model predictive control(MPC)method incorporating fuzzy compensation for regulating the anode and cathode pressures in a PEM electrolyzer.A PEM electrolyzer is then built to study pressure control and provide experimental data for the identification of the Koopman linear predictor.The identified linear predictors are used to design the Koopman MPC.In addition,the developed fuzzy compensator can effectively solve the Koopman MPC model mismatch problem.The effectiveness of the proposed method is verified through the hydrogen production process in PEM simulation.

    264-271页
    查看更多>>摘要：In wastewater treatment systems,extracting meaningful features from process data is essential for effective monitoring and control.However,the multi-time scale data generated by different sampling frequencies pose a challenge to accurately extract features.To solve this issue,a multi-timescale feature extraction method based on adaptive entropy is proposed.Firstly,the expert knowledge graph is con-structed by analyzing the characteristics of wastewater components and water quality data,which can illustrate various water quality parameters and the network of relationships among them.Secondly,multiscale entropy analysis is used to investigate the inherent multi-timescale patterns of water quality data in depth,which enables us to minimize information loss while uniformly optimizing the timescale.Thirdly,we harness partial least squares for feature extraction,resulting in an enhanced representation of sample data and the iterative enhancement of our expert knowledge graph.The experimental results show that the multi-timescale feature extraction algorithm can enhance the representation of water quality data and improve monitoring capabilities.

    查看更多>>摘要：Phase change energy storage is one of the solutions to effectively deal with the problem of intermittency and spatial and temporal mismatch between supply and demand of new energy sources(solar,wind,etc.).However,phase change materials(PCMs)suffer from low thermal conductivity,which greatly affects energy storage and release efficiency.In this study,a novel shape-stable phase change material(SSPCM)was pre-pared by mixing coconut oil(CO)as a PCM with aluminum nitride(AlN)thermally conductive reinforcing particles and vacuum impregnated into expanded graphite(EG).The results showed that the thermal conductivity of the prepared SSPCM reached 2.985 W·m-1·K-1.which was 1765％higher than that of pure CO.The latent heat of SSPCM was 83.67 J·g-1,which was 99％of the theoretical value.Furthermore,SSPCM showed excellent thermal stability and thermal cycle reliability.The proposed SSPCMs have the advantages of being renewable and simple preparation methods,which have great potential for application.

    Effect of cobalt on the activity of nickel-based/magnesium-substituted hydroxyapatite catalysts for dry reforming of methane

    Tongming SuBo GongXinling XieXuan Luo...
    281-291页
    查看更多>>摘要：The dry reforming of methane(DRM)reaction can directly convert methane(CH4)and carbon dioxide(CO2)into syngas(H2+CO),which is a promising method for achieving carbon neutralization.In this study,a series of 3Ni-xCo/Mg1HAP alloy catalysts with different ratio were synthesized by the copreci-pitation method,and the optimum Ni-Co ratio for the DRM reaction was studied.A series of charac-terization methods revealed that after Co was added,the formation of Ni-Co alloys increased the interactions between metals.However,an excess of Co inhibits the entry of Ni into the lattice of Mg1HAP,resulting in metal accumulation on the surface of the support.In addition,the introduction of Co im-proves the dispersion of Ni metal,which endows the catalyst with better catalytic activity and stability.Raman spectroscopy of the catalyst after the stability test showed that the addition of Co reduced the proportion of graphitic carbon,which was also the main reason for its improved stability.

    查看更多>>摘要：Controllable regulation of the reconstruction process for the pre-catalysts towards oxygen evolution remains as a great challenge.In this study,we report a bi-ligand strategy to facilitate the structural transformation of coordination compounds to metal oxyhydroxides during oxygen evolution with enhanced activity.A coordination compound consisting of 1,1'-ferrocene acid(Fc)and Ni2+was syn-thesized,in which terephthalic acid was introduced.The second ligand of terephthalic acid facilitates the reconstruction process,inducing an enhanced catalytic activity.In 1 mol·L-1 KOH aqueous solution,the optimized catalyst can drive a current density of 10 mA·cm-2 under a lower overpotential of 220 mV.Using this catalyst,zinc-air batteries can be prepared.The obtained zinc-air battery presents a large specific capacity of 718 mA,h·g-1 with excellent cycling stability for over 100 h far exceeding that of Pt/C+RuO2 battery fabricated with commercial catalysts.The excellent performance and low cost of this catalyst will open up broad prospects for the development of advanced systems for water electrolysis and zinc air batteries.

    查看更多>>摘要：The global green hydrogen industry is experiencing rapid growth,but the high production costs are hindering its widespread adoption.To address this challenge,it is particularly important to rationally configure a renewable energy hydrogen production system.For this purpose,the study proposes a model for capacity optimization configuration of a renewable energy hydrogen production system,which in-tegrates wind power,photovoltaic(PV)power,and concentrating solar power(CSP)with alkaline electrolyzer.It conducts capacity optimization configuration and comprehensive evaluations of the hydrogen production system across various scenarios.To minimize the total daily consumption cost,the CPLEX solver is utilized to solve the objective function and determine the capacity configuration of the renewable energy electrolysis of water hydrogen production system generator set under various sce-narios.This approach achieves a utilization rate of over 99％for renewable energy.Through compre-hensive evaluation,research has found that renewable energy-coupled hydrogen production significantly reduces generator capacity and electricity generation costs compared to separate hydrogen production,enhancing the economic efficiency of the system.The Wind-PV-CSP coupling hydrogen production system has the smallest generator assembly capacity and the lowest hydrogen production cost,which is 18.84 CNY·kg-1,significantly lower than the cost of PV-CSP coupling hydrogen production(25.78 CNY·kg-1)and wind-PV coupling hydrogen production(25.86 CNY·kg-1).It has good develop-ment prospects and plays an important role in exploring the development path of large-scale on-site consumption of new energy.

    Adaptive sliding mode control of petrochemical flare combustion process based on radial basis function network

    Jiahui LiuNan GuoYixin PengWenlu Li...
    318-326页
    查看更多>>摘要：Steam-assisted combustion elevated flares are currently the most widely used type of petrochemical flares.Due to the complex and variable composition of the waste gas they handle,the combustion environment is severely affected by meteorological conditions.Key process parameters such as intake composition,flow rate,and real-time data of post-combustion residues are difficult to measure or exhibit lag in data availability.As a result,the control methods for these flares are limited,leading to poor control effectiveness.To address this issue,this paper proposes an adaptive sliding mode control method based on the radial basis function(RBF)network.Firstly,the operational characteristics of the petrochemical flare combustion process are analyzed,and a control model for the combustion process is established based on carbon dioxide detection.Secondly,an RBF neural network-based unknown function approx-imator is designed to identify the nonlinear part of the actual operating system.Finally,by combining the control model of the petrochemical flare combustion and designing the RBF sliding mode controller with its adaptive control law,fast and stable control of the flare combustion state is achieved.Simulation results demonstrate that the designed control strategy can achieve tracking control of the petrochemical flare combustion state,and the adaptive law also accomplishes system identification.
