Comparative studies on muffle furnace thermal regeneration and microwave regeneration of antibiotic-saturated granular activated carbon (GAC) remain limited, and the mechanisms underlying their differences are still unclear. This study employed coconut-shell GAC saturated with tetracycline hydrochloride (TCH) to comparatively evaluate its regeneration performance under the two heating modes. Regeneration temperatures and holding times were varied, and regeneration efficiency, iodine value, and carbon loss were used to evaluate regeneration performance, while changes across 20 regeneration cycles were also examined. The results showed that the muffle furnace regeneration technology achieved the highest regeneration efficiency of 94.4 % at 600°C for 60 min, which was significantly higher than the 63.9 % obtained by microwave regeneration technology at 600°C for 80 min. During cyclic regeneration, thermal regeneration maintained higher regeneration performance but gradually declined to approximately 40 % by the 20th cycle, accompanied by cumulative carbon loss exceeding 35 %, whereas microwave regeneration exhibited generally lower and more unstable regeneration performance but maintained minimal carbon loss (<5 %). Characterization results revealed that the two regeneration methods differed in pore structure recovery and changes in surface functional groups, with muffle furnace regeneration enabling more complete removal of pore-blocking residues and more effective restoration of microporosity. Overall, muffle furnace thermal regeneration restored the adsorption performance of TCH-saturated GAC more effectively, providing guidance for selecting efficient regeneration methods in water treatment applications.

抗生素饱和颗粒活性炭（GAC）的马弗炉热再生和微波再生的比较研究仍然有限，其差异的机制尚不清楚。本研究采用饱和盐酸四环素（TCH）椰壳GAC，比较了其在两种加热方式下的再生性能。不同的再生温度和保温时间，用再生效率、碘值和碳损失来评估再生性能，并研究了20个再生周期的变化。结果表明，马弗炉再生技术在600℃、60 min时再生效率最高，达到94.4 %，显著高于微波再生技术在600℃、80 min时的63.9 %。在循环再生过程中，热再生保持较高的再生性能，但到第20个循环时逐渐下降到约40 %，累计碳损失超过35 %，而微波再生的再生性能普遍较低且更不稳定，但碳损失保持在最小（<5 %）。表征结果表明，两种再生方法在孔隙结构恢复和表面官能团变化方面存在差异，马弗炉再生可以更彻底地去除孔隙堵塞残留物，更有效地恢复微孔隙。总体而言，马弗炉热再生更有效地恢复了饱和tch GAC的吸附性能，为水处理应用中选择高效的再生方法提供了指导。

High-carbon ferrochrome slag (HFCS) is a large-volume hazardous metallurgical by-product. HFCS is rich in MgO, Al₂O₃, and spinel phases, which provide excellent thermal and chemical stability. However, the chromium-containing components in HFCS need careful environmental assessment due to potential hazards. This review summarizes recent advances in the synthesis, phase evolution, and high-temperature behavior of HFCS-based refractory materials. It also analyzes key influencing factors, including composition, MgO/Al₂O₃ ratio, sintering conditions, and additive selection. The formation of high-melting spinel and forsterite phases improves refractoriness, thermal shock resistance, and slag corrosion resistance. These phases also help stabilize Cr (III) within spinel lattices and reduce chromium leaching during regular operation. Continuous forsterite frameworks limit liquid-phase formation at high temperatures, thereby enhancing structural reliability and lowering the risk of rapid refractory deterioration. However, high slag basicity, CaO-rich environments, and strongly oxidizing atmospheres can destabilize chromium-containing phases and increase the risk of dangerous chromium release. Challenges remain, including feedstock variability, long-term chromium stability, and the absence of standardized assessment protocols. Future HFCS research should focus on designing refractory compositions, controlling microstructure, utilizing multiple solid waste streams synergistically, and developing new refractory materials. These efforts should be complemented by long-term leaching studies, life-cycle analyses, and pilot-scale testing to ensure safety and sustainability in industrial applications.

高碳铬铁渣是一种体积较大的冶金副产物。HFCS富含MgO、Al2O3和尖晶石相，具有优异的热稳定性和化学稳定性。然而，由于高果糖玉米糖浆中的含铬成分存在潜在危害，需要进行仔细的环境评估。本文综述了氢氟碳化物基耐火材料的合成、相演化和高温性能方面的最新进展。分析了主要影响因素，包括组成、MgO/Al2O3比、烧结条件和添加剂的选择。高熔点尖晶石和橄榄石相的形成提高了耐火度、抗热震性和抗渣蚀性。这些相还有助于稳定尖晶石晶格内的Cr (III)，并在常规操作中减少铬的浸出。连续的forsterite框架限制了高温下液相的形成，从而提高了结构的可靠性，降低了耐火材料快速变质的风险。然而，高矿渣碱度、富cao环境和强氧化气氛会使含铬相不稳定，增加危险铬释放的风险。挑战依然存在，包括原料的可变性、长期铬的稳定性以及缺乏标准化的评估方案。未来HFCS的研究应集中在耐火材料成分设计、微观结构控制、多种固体废物流协同利用、新型耐火材料开发等方面。这些努力应辅以长期浸出研究、生命周期分析和中试规模试验，以确保工业应用的安全性和可持续性。

This study presents a novel approach for the capture of high-purity biogenic CO₂ to synthesise sodium carbonate from concentrated NaOH solutions (up to 50 wt%), which has not been previously reported and supported with experimental evidence before. This strategy enables the direct processing of high-purity CO₂ (>95 %) from concentrated biogenic sources, such as those in fermentative industries. A customised gas-liquid mixing reactor overcomes viscosity and precipitation challenges, allowing 97.5 % CO₂ capture efficiency and mass transfer coefficients up to 16.13 ± 0.30 mm/s (n = 3), significantly exceeding conventional NaOH-based systems. The optimised hydrodynamic conditions and thermal enhancement occurred in the 88–91 °C temperature range, leading to the production of Na₂CO₃ with 99.95 % purity that meets commercial dense soda standards, with water as the only by-product. Applied to fermentative industry, this process offers a new pathway towards a greener sodium carbonate production, eliminating CaCl₂ waste, and leading to the mitigation of up to −8.54 Mt CO₂/year.

本研究提出了一种新的方法，用于捕获高纯度的生物源二氧化碳，从浓缩NaOH溶液中合成碳酸钠（高达50 wt%），这在以前没有报道过，也没有实验证据支持。这一策略使得从浓缩的生物源，如发酵工业中，直接处理高纯度二氧化碳（>95 %）成为可能。定制的气液混合反应器克服了粘度和沉淀的挑战，允许97.5% %的二氧化碳捕获效率和传质系数高达16.13 ± 0.30 mm/s (n = 3)，大大超过传统的naohs系统。优化的流体动力条件和热增强发生在88-91°C的温度范围内，导致生产的Na2CO3纯度为99.95 %，符合商业浓碱标准，水是唯一的副产品。应用于发酵工业，该工艺为更环保的碳酸钠生产提供了一条新途径，消除了CaCl2的浪费，并导致每年减少高达- 854万吨二氧化碳。

Molten salt oxidation (MSO) is a promising technology for treating sulfur-containing organic waste such as cation exchange resin (CER), but achieving complete sulfur retention remains a critical challenge. Although adding oxide modifiers is a known strategy, their precise enhancement mechanism has been unclear, hindering the rational selection of optimal additives. The primary innovation stems from a thermodynamic analysis that first revealed a key discrepancy: the performance enhancement from oxide modifiers cannot be explained by SO₂ capture, as the base carbonate salt is already highly effective. This finding redirected the investigation, leading to the identification of H₂S capture from oxygen-deficient zones as the critical and previously overlooked mechanism for improving sulfur retention. This new framework identifies earth-abundant and non-toxic Fe₂O₃ as the superior modifier. Experiments confirm that its addition increases the overall acid gas neutralization efficiency from 81.32 % to a leading 92.19 % without introducing secondary safety hazards. This enhanced performance is primarily attributed to the superior H₂S capture capability of Fe₂O₃, with further mechanistic analyses revealing that it also induces a more intense exothermic oxidation and alters the decomposition of the CER to a layered exfoliation pathway. Crucially, the captured sulfur is chemically immobilized within the spent salt, effectively preventing secondary airborne pollution and confining the contaminants to a stable solid phase for safe final disposal. Furthermore, the resulting spent salt is identified as an ideal precursor for iron phosphate glass vitrification, transforming waste byproducts into functional assets for enhanced radionuclide stabilization and volume minimization. These findings establish a thermodynamics-guided engineering approach, replacing extensive experimental screening and providing a practical strategy for the safe and efficient disposal of sulfur-containing organic waste.

熔盐氧化（MSO）是一种很有前途的处理含硫有机废物（如阳离子交换树脂（CER））的技术，但实现完全的硫保留仍然是一个关键的挑战。虽然添加氧化改性剂是一种已知的策略，但其精确的增强机制尚不清楚，阻碍了合理选择最佳添加剂。主要的创新源于热力学分析，该分析首次揭示了一个关键的差异：氧化物改进剂的性能增强不能用SO2捕获来解释，因为基础碳酸盐已经非常有效。这一发现改变了研究方向，导致从缺氧区捕获H2S作为改善硫保留的关键和以前被忽视的机制。这个新框架确定了地球上丰富且无毒的Fe2O3是优越的改性剂。实验证实，在不引入二次安全隐患的情况下，将酸性气体的整体中和效率从81.32 %提高到领先的92.19 %。这种增强的性能主要归功于Fe2O3优越的H2S捕获能力，进一步的机理分析表明，它还会引起更强烈的放热氧化，并将CER的分解转变为层状剥离途径。至关重要的是，捕获的硫被化学固定在废盐中，有效地防止了二次空气污染，并将污染物限制在稳定的固相中，以便安全的最终处置。此外，由此产生的废盐被确定为磷酸铁玻璃玻璃化的理想前体，将废物副产品转化为增强放射性核素稳定和体积最小化的功能资产。这些发现建立了一种热力学指导的工程方法，取代了广泛的实验筛选，并为安全有效地处理含硫有机废物提供了实用的策略。

Using existing pipelines to transport hydrogen-blended natural gas is an efficient and cost-effective approach. Nevertheless, the mixture of hydrogen and natural gas may increase the risk of leakage and associated hazards. For gas terminal stations such as gate stations and compressor stations, which are usually located near residential areas, it is necessary to implement leakage detection from outdoor pipelines to ensure the safety of the pipeline transportation system. Acoustic signal-based natural gas pipeline leakage detection is considered one of the most effective and cost-efficient methods available today. However, most existing acoustic signal extraction techniques rely on a single domain, which can lead to information loss in complex environments. To address this, this paper proposes a new framework for HBNG leakage detection, combining multi-domain acoustic feature extraction methods with deep learning algorithms. By extracting and combining frequency-domain, time-domain, and statistical features of leakage sounds, and after preprocessing, a lightweight convolutional neural network with the Efficient Channel Attention (ECA) mechanism is introduced to capture both global and local features of the signals in real-time, while ensuring high accuracy and a low parameter count for the model. Finally, the effectiveness and generalization ability of the proposed method were validated on a dataset of HBNG natural gas and nitrogen gas leaks constructed in this study, and a comparison with other detection methods was conducted. The results showed that the accuracy of this method reached 97.58 %, with good robustness.

利用现有管道输送氢混合天然气是一种高效且经济的方法。然而，氢气和天然气的混合物可能会增加泄漏和相关危害的风险。对于通常位于居民区附近的闸站、压缩站等燃气终端站，有必要从室外管道进行泄漏检测，以确保管道运输系统的安全。基于声信号的天然气管道泄漏检测被认为是当今最有效和最经济的方法之一。然而，大多数现有的声信号提取技术依赖于单一的域，这可能导致复杂环境下的信息丢失。为了解决这一问题，本文提出了一种新的HBNG泄漏检测框架，将多域声学特征提取方法与深度学习算法相结合。通过提取和组合泄漏声音的频域、时域和统计特征，并经过预处理，引入具有高效通道注意（ECA）机制的轻量级卷积神经网络，实时捕获信号的全局和局部特征，同时确保模型的高精度和低参数计数。最后，在本研究构建的HBNG天然气和氮气泄漏数据集上验证了所提方法的有效性和泛化能力，并与其他检测方法进行了比较。结果表明，该方法的准确率达到97.58 %，具有良好的鲁棒性。

Thermo-chemical conversion (TCC) is an effective strategy in the detoxification of waste salt (WS) containing hazardous organics, which can be enhanced by molten salt, e.g., molten NaOH-KOH. However, the microscopic process remains largely unclear. With the WS collecting from a pesticide enterprise, this study comprehensively investigated the pyrolysis and combustion behaviors based on TG and FTIR. Particularly, molten NaOH-KOH mediation was explored. The results showed that combustion appeared to be more advantageous than pyrolysis for WS detoxification. Moreover, attributing to the enhanced heat transfer and catalytic activity of molten NaOH-KOH, the detoxification was promoted, manifested as a decrease in the peaked temperature of organic reactions (from 192 ℃ to 147 ℃). In addition, the emissions of C_xH_y, CO, and SO₂ decreased by 55.4 %, 88.2 %, and 74.1 %, respectively, due to the trapping effect by molten NaOH-KOH. Afterwards, continuous operation was conducted, and the results showed that the total organic carbon of the treated WS reduced evidently by 75.9 %, indicating stable and satisfactory performance. This study is of significance for understanding the WS transformation during TCC, especially when the molten salt is involved. The effective suppression of gas emissions under controlled conditions and the stable performance during continuous operation demonstrate the potential of this process for large-scale applications in the future.

热化学转化（TCC）是含有害有机物的废盐（WS）解毒的有效策略，可通过熔融盐（如熔融NaOH-KOH）来增强。然而，微观过程在很大程度上仍不清楚。本研究以某农药企业收集的WS为研究对象，基于热重分析（TG）和红外光谱（FTIR）对其热解燃烧行为进行了全面研究。特别探讨了熔融NaOH-KOH的调解作用。结果表明，燃烧解毒比热解解毒更有利。此外，由于NaOH-KOH熔液的传热和催化活性增强，促进了脱毒，表现为有机反应的峰值温度从192℃降低到147℃。此外，由于NaOH-KOH的俘获作用，CxHy、CO和SO2的排放量分别下降了55.4% %、88.2% %和74.1 %。之后进行连续运行，结果表明，处理后的WS总有机碳明显减少了75.9% %，性能稳定，令人满意。本文的研究对了解TCC过程中WS的转化过程，特别是涉及熔盐的过程具有重要意义。在控制条件下有效抑制气体排放和连续运行期间的稳定性能表明该工艺在未来大规模应用的潜力。

In addition, the emissions of C<sub><em>x</em></sub>H<sub><em>y</em></sub>, CO, and SO<sub>2</sub> decreased by 55.4 %, 88.2 %, and 74.1 %, respectively, due to the trapping effect by molten NaOH-KOH. Afterwards, continuous operation was conducted, and the results showed that the total organic carbon of the treated WS reduced evidently by 75.9 %, indicating stable and satisfactory performance. This study is of significance for understanding the WS transformation during TCC, especially when the molten salt is involved. The effective suppression of gas emissions under controlled conditions and the stable performance during continuous operation demonstrate the potential of this process for large-scale applications in the future.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"209 ","pages":"Article 108548"},"PeriodicalIF":7.8,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146109776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lithium aluminosilicate (LAS) glass, primarily composed of Al₂O₃, SiO₂, and Li₂O, is mainly sourced from discarded mobile phone screens. Its highly stable chemical nature poses challenges such as difficult disposal and low recovery efficiency. This study introduces an innovative integrated process that combines H₂SO₄ baking -induced Li phase transformation with low-energy Li extraction, enabling and directional Li recovery. The process involved transforming the highly stable Li-phase in LAS into soluble Li₂SO₄ via H₂SO₄ maturation, followed by water leaching, achieving a remarkable Li leaching efficiency of 98.23 %. Kinetic analysis based on the shrinking-core model demonstrated that Li extraction during maturation was governed by internal diffusion mechanisms. The effectiveness of various precipitants was systematically evaluated to address the Al–Li separation challenge in the leachate. The experimental results showed that well-crystallized Al(OH)₃ particles was precipitated with an efficiency of over 99.8 % under optimized conditions (pH=5.0) using NaHCO₃ as the precipitant. This approach significantly reduced Li coprecipitation loss from 42.93 % (conventional NaOH method) to only 4.02 %. After Al removal, a facile process involving HBL121 solvent extraction and H₂SO₄ stripping enriched Li effectively and selectively, enabling the direct preparation of Li₂CO₃ after adjusting the solution pH to alkaline conditions. This process, which integrates H₂SO₄ maturation with low-energy lithium extraction, offers significant potential for industrial applications in the recovery of Li from LAS glass.

硅铝酸锂（LAS）玻璃主要由Al₂O₃、SiO₂、Li₂O组成，主要来源于废弃的手机屏幕。其高度稳定的化学性质给其处理困难和回收率低带来了挑战。本研究介绍了一种创新的集成工艺，将H2SO4焙烧诱导的锂相变与低能量锂提取相结合，实现了锂的定向回收。该工艺通过H2SO4成熟将LAS中高度稳定的Li相转化为可溶的Li₂SO₄，然后进行水浸，Li浸出效率达到98.23 %。基于收缩核模型的动力学分析表明，成熟过程中锂的提取受内部扩散机制控制。系统地评价了各种沉淀剂的有效性，以解决渗滤液中铝锂分离的挑战。实验结果表明，在优化条件下（pH=5.0），以NaHCO₃为沉淀剂，可以得到结晶良好的Al(OH)3颗粒，沉淀效率可达99.8 %以上。该方法将Li共沉淀损失从42.93 %（传统的NaOH方法）显著降低到4.02 %。去除Al后，采用HBL121溶剂萃取+ H₂SO₄汽提的简单工艺有效选择性富集Li，将溶液pH调整为碱性条件后可直接制备Li2CO3。该工艺将H2SO4成熟与低能量锂提取相结合，在LAS玻璃中回收锂的工业应用中具有巨大的潜力。

This study provides a detailed assessment of bioengineered chitosan as an eco-friendly adsorbent for multi-metal-contaminated industrial wastewater, integrating physicochemical characterization, mechanistic analysis, and artificial intelligence (AI)-based modeling. The chitosan displayed a high degree of deacetylation (85 %), mesoporosity (12.4 nm), and a point of zero charge (pHpzc = 6.4), enhancing metal chelation and electrostatic adsorption. Effluent from the Gafsa-Metlaoui phosphate washing plant presented elevated concentrations of Cd²⁺ (26.5 mg L⁻¹), Pb²⁺ (13.7 mg L⁻¹), and Mo⁶⁺ (55.8 mg L⁻¹), surpassing regulatory thresholds. Batch experiments achieved maximum removal efficiencies of 90 ± 0.1 % for Pb, 85 ± 0.9 % for Cd, 75 ± 0.2 % for Cu, and 70 ± 0.4 % for Zn under optimized parameters (pH 6.5, 120 mg, 180 min). Four machine learning models (RF, GBM, SVM, and ANN) trained on experimental datasets further predicted adsorption performance, with Random Forest achieving the highest accuracy (R² = 0.954; RMSE = 0.53). Three-dimensional response surface analysis highlighted the critical impact and synergistic effects of operational conditions (pH, contact time, sorbent mass) on adsorption efficiency and identified optimal zones for different metals. Metal-specific adsorption dynamics were systematically correlated with physicochemical descriptors (polarizability, charge density, hydration energy, and redox potential), providing mechanistic insight into selective metal chelation and validating Hard and Soft Acids and Bases (HSAB) theory. This study uniquely integrates metal descriptor-driven mechanistic understanding with AI-guided optimization and operational parameter analysis, underscoring chitosan’s efficiency as a multi-metal sorbent and providing a practical approach for designing advanced, scalable wastewater treatment strategies.
