Photosensitized heterogeneous CO_(2) reduction(PHCR)has emerged as a promising means to convert CO_(2) into valuable chemicals,however,challenged by the relatively low carbonaceous product selectivity caused by the competing hydrogen evolution reaction(HER).Here,we report a PHCR system that couples Ru(bpy)32+photosensitizer with{001}faceted LiCoO_(2) nanosheets photocatalyst to simultaneously yield 21.2 and 722μmol·g^(-1)·h^(-1) of CO,and 4.42 and 108μmol·g^(-1)·h^(-1) of CH4 under the visible light and the simulated sunlight irradiations,respectively,with completely suppressed *** experimental and theoretical studies reveal that the favored CO_(2) adsorption on the exposed Li sites on{001}faceted LiCoO_(2) surface is responsible for the completely suppressed HER.

In this work, continuous carbon dioxide (CO2) absorption-desorption experiments under simulated flue gas conditions and techno-economic analysis of CO2 capture using a novel water-lean ionic liquid (IL) absorbent were comprehensively combined to evaluate the feasibility of industrial applications. Thermodynamic and kinetic properties of the absorbent such as heat capacity, thermal conductivity, and absorption rate were explored and a reliable thermodynamic model was conducted. Meanwhile, continuous absorption-desorption experiments were carried out using a laboratory-scale continuous flow system (LCFS) to optimize operational parameters and assess the absorbent stability. Under optimal conditions, the CO2 concentration in the purified gas can be reduced to 0.70%, and the capture efficiency was as high as 95.76%. After 650 hours of continuous experiments under simulated flue gas, the IL concentration in the absorbent remained essentially unchanged, showing excellent stability. Based on above experimental results, a process model was developed in ASPEN Plus and validated. The validated model was further scaled up to a commercial scale and a techno-economic analysis was performed to evaluate the energy consumption and cost. The regeneration energy consumption (Qreg) for the absorbent was 1.31 GJ tCO2-1, and the total cost of capture was 38.81 $ tCO2-1, indicating strong potential for industrial application. © 2025, The Authors.

The project manager's role and influence on the project's overall outcome have fascinated many academicians, researchers, and practitioners. The project manager's leadership and human skills play a vital role in the project's outcome;therefore, it is imperative for these competencies to be identified, learned, and leadership styles to be adopted. This study aims to define the most relevant competencies to multidimensional project success and their interrelationship. The quantitative method was used by applying a survey to project managers and team members working in the public sector of Pakistan. The results suggest that a combination of emotional, managerial intelligence, and transformational leadership are stronger predictors of multidimensional public project success. This study has shown that management and leadership need to be integrated to achieve better results. Project managers need to combine soft and hard skills, leadership competencies, and management to engage with people and be effective in terms of processes, tasks, and objectives. © 1973-2011 IEEE.

An Integrated process Coupling Biooxidation and Fenton Oxidation for Treatment of Arsenic-Containing Acid Mine Drainage

SSRN 2024年

作者： Shen, Cailong Chen, Yanzhen Yang, Li Zhang, Guangji Yang, Chao State Key Laboratory of Biochemical Engineering CAS Key Laboratory of Green Process and Engineering Institute of Process Engineering Chinese Academy of Sciences Beijing100190 China School of Chemical Engineering University of Chinese Academy of Sciences Beijing100049 China

Arsenic-containing acid mine drainage (AMD) is a serious water pollution problem worldwide. In present study, an integrated process coupling biooxidation and Fenton oxidation was proposed for treatment of simulated AMD with high As(III) concentration. The biooxidation experiments showed that Acidithiobacillus ferrooxidans was resistant to at least additional H2O2 of 90 mM when cultured in 100 mL Leathen medium with 5 g FeSO4·7H2O. The XRD and SEM confirmed the formation of crystalline jarosite and amorphous schwertmannite. The AMD treatment was carried out with 300 mg/L As(III) in shaking flasks, and finally 73.15% arsenic was removed in 96 h. The formed precipitates exhibited 2.117 mg/L arsenic in leachate in the toxicity characteristic leaching procedure (TCLP) test, which was below the United states Environmental Protection Agency’s limit of 5 mg/L. However, the precipitates formed in the treatment experiments without additional H2O2 exhibited leached arsenic of 6.492 mg/L in the TCLP test. The results suggested a better stability of the formed precipitates in the integrated arsenic removal process. The XPS suggested that the improved stability was attributed to that the formed precipitates mainly contained As(V) instead of As(III). Meanwhile, the ICP-OES and ASV showed a rapid As(III) oxidation in the solution immediately after the addition of H2O2. The arsenic removal process was carried out in a 5 L stirred tank reactor to evaluate the feasibility on a larger scale. The results confirmed that biooxidation was not inhibited by additional H2O2 from the point of view of the metabolic activity of bacteria. About 85% arsenic settled down in 120 h, and the formed precipitates exhibited a good stability of 0.534 mg/L arsenic leaching concentration in the TCLP test, indicating the potential of the arsenic removal process for further application. © 2024, The Authors.
