Coal-derived sludge, a solid waste produced by the coal industry, offers potential opportunities for resource recovery due to its high organic matter. However, its products face challenges related to low utilization efficiency and economic value. Effective and clean treatment of coal-derived sludge is essential for sustainable development. Herein, we studied the co-pyrolysis treatment of coal-derived sludge and low-rank coal at different temperatures (500 °C−900 °C) and pretreatment methods (mechanical mixing and hydrothermal co-treatment). The co-pyrolysis of sludge and coal could increase the pyrolysis char yield and H₂ yield, as well as reduce CO₂ emissions. The hydrothermal co-treatment significantly improved the cleanliness of the co-pyrolysis treatment. Then we conducted a comprehensive analysis of the properties of the pyrolysis char using different characterization techniques. In order to better evaluate the distribution of co-pyrolysis product yield, six machine learning models were developed to predice co-pyrolysis char yield. The best model-predicted values showed excellent predictive performance when compared to the experimental values at high pyrolysis temperatures (≥700 °C). This study provided a new perspective on the resource utilization of coal-derived sludge and low-rank coal.

煤炭污泥是一种由煤炭工业产生的固体废物，由于其有机物含量高，为资源回收提供了潜在的机会。然而，其产品面临着利用效率和经济价值不高的挑战。有效、清洁地处理煤泥对可持续发展至关重要。本文研究了不同温度（500℃~ 900℃）下煤源污泥和低阶煤的共热解处理及预处理方法（机械混合和水热共处理）。污泥与煤共热解可提高热解炭产率和H2产率，减少CO2排放。水热共处理显著提高了共热解处理的清洁度。然后采用不同的表征技术对热解炭的性质进行了综合分析。为了更好地评估共热解产物产率的分布，开发了6个机器学习模型来预测共热解炭产率。在较高热解温度（≥700℃）下，与实验值相比，最佳模型预测值具有较好的预测性能。该研究为煤泥和低阶煤的资源化利用提供了新的思路。

To better understand the mineralogical, release-transformation patterns and ash deposition of Mg-bearing minerals, Wucaiwan Coal (WCW), Meihuajing Coal (MHJ), and slag of water wall from a power plant were collected and high-temperature ash transformation experiments were conducted. X-ray fluorescence (XRF), X-ray diffractometer (XRD), scanning electron microscope coupled with energy dispersive spectrometer (SEM-EDS), and simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC) were used to analyze the mineralogy, chemical composition, and characteristics. The results show that the Mg-bearing minerals in high-alkali coal and ash include dolomite, chlorite, forsterite, melilite, akermanite, diopside, bredigite, pyroxene, periclase, spinel, and magnesioferrite. During combustion, the release of Mg is affected by its mode of occurrence. Mg-bearing minerals gradually transform into thermally stable minerals, including spinel, periclase, and pyroxene, with the transformation pathway being dolomite → Mg-bearing silicate (diopside, akermanite, bredigite) → pyroxene/spinel/periclase. Moreover, Ca has a competitive and synergistic effect on the transformation of Mg-bearing minerals, which depends on the relative content of Si and Al in ash. Spinel is the primary Mg-bearing mineral in high-temperature ash, and Fe may substitute for both Mg and Al. In coal combustion, the formation of Mg-Al-Fe and Mg-Al-Fe-Si-Ca eutectic systems from Mg-bearing minerals causes slagging on the water wall and worsens water wall corrosion.

为了更好地了解含镁矿物的矿物学、释放转化模式和灰分沉积规律，收集了某电厂五彩湾煤、梅花井煤和水壁渣，进行了高温灰分转化实验。采用x射线荧光（XRF）、x射线衍射（XRD）、扫描电镜-能谱仪（SEM-EDS）、同时热重法和差示扫描量热法（TG-DSC）等方法分析了样品的矿物学、化学成分和特征。结果表明：高碱煤和高碱灰中的含镁矿物主要有白云石、绿泥石、橄榄石、镁长石、钾长石、透辉石、钾长石、辉石、尖晶石、镁铁素体等。在燃烧过程中，Mg的释放受其发生方式的影响。含镁矿物逐渐转化为热稳定矿物，包括尖晶石、方晶石、辉石，转化路径为白云岩→含镁硅酸盐（透辉石、角长石、辉长石）→辉石/尖晶石/辉长石。此外，Ca对含镁矿物的转化具有竞争和协同作用，这取决于灰分中Si和Al的相对含量。尖晶石是高温灰分中主要的含镁矿物，Fe可以替代Mg和Al。煤燃烧过程中，含镁矿物形成Mg-Al-Fe和Mg-Al-Fe- si - ca共晶体系，导致水壁结渣，加剧水壁腐蚀。

Hydrothermal carbonization (HTC) is widely recognized as a promising approach for enhancing the fuel properties of agricultural waste. This study investigated the HTC characteristics of corn stalks, focusing on the effect of secondary char (SC) on the fuel properties and pyrolysis behaviors of hydrochars at different temperature and liquid-solid ratio (LSR). Results showed that lower LSR increased the carbon content and higher heating value of hydrochars. Higher temperature strengthened the effect of LSR. At 240 °C, hydrochar yield decreased from 58.56 % to 45.59 % as the LSR increased. The higher LSR enhanced hydrolysis and promoted the transfer of organic components to aqueous phase, thereby facilitating SC formation with a content as high as 12.10 %. The increase in SC was accompanied by larger carbon microspheres and greater deposition coverage, resulting in reduced specific surface area and elevated oxygen-containing functional groups. The covering of SC strengthened the pyrolysis-like reaction of primary char (PC) during HTC (limited by contact with water). These changes influenced subsequent pyrolysis behavior, with PC tending to produce phenols at low LSR but aromatic hydrocarbons at high LSR. This work could enhance the understanding of SC and provide a practical approach combining HTC and extraction to regulate bio-oil preparation by pyrolysis.

水热碳化（HTC）被广泛认为是提高农业废弃物燃料性能的一种有前途的方法。本研究研究了玉米秸秆的HTC特性，重点研究了在不同温度和液固比（LSR）下，二次焦（SC）对氢炭燃料特性和热解行为的影响。结果表明，LSR越低，烃类碳含量越高，热值越高。温度越高，LSR的效果越强。在240℃时，随着LSR的增加，烃类产率从58.56%下降到45.59%。较高的LSR促进了水解，促进了有机组分向水相的转移，从而促进了SC的形成，其含量高达12.10%。SC的增加伴随着更大的碳微球和更大的沉积覆盖率，导致比表面积的减少和含氧官能团的增加。SC的覆盖增强了原炭（PC）在HTC过程中的类热解反应（受水接触限制）。这些变化影响了随后的热解行为，PC倾向于在低LSR下生成酚类，而在高LSR下生成芳香烃。本研究有助于加深对生物油热解过程的认识，并为生物油热解过程中HTC与萃取相结合调控生物油的制备提供了可行的途径。

The global push towards a hydrogen economy fuels hydrogen production from various sources. A crucial step in enriching hydrogen and reducing CO in syngas derived from carbon-based hydrogen production is the water-gas shift reaction (WGSR). Given the equilibrium-limited nature of WGSR, low temperatures are necessary to reduce carbon monoxide concentrations to the desired level. Traditionally, iron‑chromium (Fe/Cr) and copper‑zinc (Cu/Zn) catalysts have been widely used at high and low temperatures, respectively. Numerous studies have focused on developing optimal WGS catalysts with the desired characteristics and efficiency. This review extensively discusses various catalysts for different stages of WGSR, including low, medium, high-temperature, and sour WGS catalysts. However, understanding the contrast between the redox and associative mechanisms and the nature of intermediates in the WGS pathway remains unclear. A detailed study of the WGSR pathway is imperative to develop highly active and stable catalysts. Various experimental kinetic values and models have also been reported to elucidate the WGSR mechanism at different temperatures. The primary deactivation sources of WGS catalysts have been discussed to highlight recent advances to improve catalyst performance. The contribution of computational methods such as Density Functional Theory (DFT) to developing WGS catalysts is also explored. Furthermore, the review addresses the challenges encountered in the WGSR, and recommendations and conclusions are drawn to guide future research efforts.

全球对氢经济的推动推动了各种来源的氢生产。在碳基制氢产生的合成气中富集氢和还原CO的关键步骤是水气转换反应（WGSR）。考虑到WGSR的平衡限制性质，低温是将一氧化碳浓度降低到所需水平所必需的。传统上，铁-铬（Fe/Cr）和铜-锌（Cu/Zn）催化剂分别在高温和低温下广泛使用。许多研究都集中在开发具有理想特性和效率的最佳WGS催化剂上。本文综述了不同阶段的WGSR催化剂，包括低、中、高温和酸性WGS催化剂。然而，对氧化还原和结合机制之间的对比以及WGS途径中中间体的性质的理解仍不清楚。对WGSR途径的深入研究是开发高活性、稳定催化剂的必要条件。不同的实验动力学值和模型也被报道来阐明不同温度下WGSR的机理。讨论了WGS催化剂的主要失活源，重点介绍了提高催化剂性能的最新进展。本文还探讨了密度泛函理论（DFT）等计算方法对开发WGS催化剂的贡献。此外，该综述还解决了《世界气候变化研究报告》中遇到的挑战，并提出了指导未来研究工作的建议和结论。

In this study, the oligomerization of 1-octene was investigated using various zeolites through both experimental and machine learning (ML) approaches. The structural characteristics of the zeolites and experimental conditions were used as input parameters to analyze the feature importance of each key factor on the oligomerization of 1-octene. By quantifying these influences, the reaction mechanism was elucidated, and a methodology for maximizing the oligomerization reaction was developed. The ML methods employed in this study were SHapley Additive exPlanations (SHAP) and Sure Independence Screening and Sparsifying Operator (SISSO). While the SHAP method is a well-validated conventional approach, it has limitations due to its high data requirements. Therefore, the SISSO method was applied, as it requires fewer data points and offers a transparent computational process. SISSO provided results in the form of human-interpretable equations, allowing for an analysis of these equations to deepen insights into the reaction mechanism.

Widely sourced precursors for hard carbon with high performances are still a major challenge for industrializing sodium-ion batteries. Herein, long-flame coal was adopted as the precursors to prepare hard carbon by carbonization at different temperatures, and the influences of carbonization temperatures on the microstructure together with electrochemical properties of hard carbon were systematically investigated. With elevating carbonization temperature, carbon layer spacing, defect concentration and C − O, CO functional groups of hard carbon all gradually decrease. The hard carbon prepared at 1500 °C (BHC-1500) demonstrates 38 % of the pseudo-graphite carbon with an average carbon layer spacing of 0.360 nm, a specific surface area of 31.2 m²/g and appropriate defect concentration (I_D1/I_G of 1.50). As anode active materials, BHC-1500 possesses a specific capacity of 254 mAh/g at 20 mA/g with initial coulombic efficiency of 79 %, a rate performance of 24.8% in 20-1000 mA/g, a capacity retention of 72 % after 1000 cycles at 500 mA/g, suggesting the excellent electrochemical sodium storage performances, which may be concerned with the highest proportion of pseudo-graphite carbon, appropriate carbon layer spacing, functional groups and defect concentration. The ex-situ XRD test confirms sodium storage mechanism of “adsorption-intercalation/filling” in hard carbon. This work can provide new ideas for clean utilization of long-flame coal and developing high performances anode active materials for SIBs.

来源广泛的高性能硬碳前驱体仍是钠离子电池产业化的一大挑战。本文采用长焰煤为前驱体，通过不同温度下的碳化制备硬质碳，并系统研究了碳化温度对硬质碳微观结构和电化学性能的影响。随着碳化温度的升高，硬碳的碳层间距、缺陷浓度和 C - O、CO 官能团均逐渐减小。在 1500 °C 下制备的硬碳（BHC-1500）具有 38% 的伪石墨碳，平均碳层间距为 0.360 nm，比表面积为 31.2 m2/g，并具有适当的缺陷浓度（ID1/IG 为 1.50）。作为阳极活性材料，BHC-1500 在 20 mA/g 条件下的比容量为 254 mAh/g，初始库仑效率为 79%，在 20-1000 mA/g 条件下的速率性能为 24.8%，在 500 mA/g 条件下循环 1000 次后的容量保持率为 72%，表明其具有优异的电化学储钠性能，这可能与最高比例的伪石墨碳、适当的碳层间距、官能团和缺陷浓度有关。原位 XRD 测试证实了硬碳中 "吸附-插层-填充 "的钠存储机理。该研究为长焰煤的清洁利用和开发高性能 SIB 负极活性材料提供了新思路。

Biomass gasification has increased due to its ability to provide high-temperature heat, making it promising for the decarbonisation of industrial processes. The economic and technical challenges of large-scale operations need to be addressed by focusing on small-sized gasifiers, while the use of low-grade biomass, is essential to increase the flexibility and sustainability of the plant. However, the utilisation of low-grade biomass is hindered by challenges stemming from variations in the particle distribution and shape, which significantly impact the fluidisation process and overall. In this research, the gasification of shredded municipal waste wood in a pilot-scale bubbling fluidised bed reactor was demonstrated, and the fluid-dynamics and gas production were assessed. The gasification process was yielding a gas with a lower heating value between 3.5 MJNm⁻³ and 3.9 MJNm⁻³ and a cold gas efficiency (CGE) of 46.4 %–48.6 %. Notably, these CGE values are consistent with pilot-scale setups, where CGE values above 50 % are typically not achievable because of poor insulation standards. The reactor's conical shape facilitated dynamic fluid regime transitions, ensuring efficient gas-solid interactions. This design allowed optimisation of fluidisation by accommodating particles of varying sizes throughout the reactor's height, thereby promoting efficient gasification suitable for industrial applications with diverse biomass feedstocks.

生物质气化因其提供高温热量的能力而得到越来越多的关注，使其在工业过程的脱碳方面大有可为。大规模运营所面临的经济和技术挑战需要通过关注小型气化炉来解决，而使用低品位生物质对于提高工厂的灵活性和可持续性至关重要。然而，低品位生物质的利用受到颗粒分布和形状变化带来的挑战的阻碍，这对流化过程和整体产生了重大影响。在这项研究中，我们演示了在中试规模的鼓泡流化床反应器中气化城市废木屑的过程，并对流体动力学和气体产量进行了评估。气化过程产生的气体热值较低，介于 3.5 MJNm-3 和 3.9 MJNm-3 之间，冷气效率 (CGE) 为 46.4 %-48.6 %。值得注意的是，这些 CGE 值与中试规模的装置一致，在中试规模装置中，由于隔热标准较差，CGE 值通常无法达到 50 % 以上。反应器的圆锥形有利于流体的动态转换，确保了有效的气固相互作用。这种设计通过在反应器的整个高度上容纳不同大小的颗粒来优化流化，从而促进了高效气化，适用于各种生物质原料的工业应用。

This study proposed an integrated intelligent control system in one municipal solid waste incineration power plant to improve the system's control accuracy, economic performance and environmental impact, including the intelligent combustion, intelligent denitrification, intelligent desulfurization and intelligent soot-blowing control subsystems. The precise detection and adjustment of the key operational parameters was achieved by integrating these modules into the existing distributed control system. A comparative analysis of the operation data between pre-optimization and post-optimization states was conducted to assess the changes in the key operational and economic parameters. The results indicate that the introduction of the intelligent control module can significantly improve the system stability and parameter control accuracy, thereby enhancing the economic efficiency of the waste incineration power plant and reducing the operation workload and the pollutants emissions. Specifically, the standard deviations of main steam flowrate and pressure decreased by 45.1 % and 60.7 %, respectively. Furthermore, the consumptions of the ammonia water and lime slurry were reduced by 38.2 % and 23.2 %, respectively, while the auxiliary power consumption rate declined by two percentage points, and the power generation per ton of waste increased by 4.2 %. These improvements not only strengthen the economic benefits but also effectively reduce the pollutants emissions.

Combining stratified lean-burn techniques with methanol offers a promising path to achieving high efficiency and low emissions in direct-injection spark-ignition (DISI) engines. This work compares the stratified and homogeneous-stratified lean-burn characteristics of methanol/gasoline fuels on a DISI engine. Combustion and emissions characteristics under two stratified lean-burn strategies were investigated. The results indicate that compared to double-injection stratified lean-burn (DISL), single-injection stratified lean-burn (SISL) leads to more timely combustion, which deteriorates more slowly as the excess air ratio increases. Using M20 fuel with SISL achieves a higher tolerance for air dilution. At the same excess air ratio, SISL results in higher maximum in-cylinder pressure and combustion temperature, but lower exhaust temperature. The economic zone for SISL occurs with M40 fuel at λ = 1.3–1.6, whereas DISL's economic zone is within λ = 1.1–1.3. When λ is below 1.5, SISL produces higher hydrocarbon (HC) emissions but lower nitrogen oxides (NOx) emissions. However, as λ exceeds 1.5, HC emissions from DISL increase sharply while NOx emissions decrease significantly. The particle concentration from SISL is at least an order of magnitude higher than that from DISL, with particle size distribution forming a unimodal curve centered around accumulation mode particles. Conversely, DISL exhibits a quasi-bimodal distribution.

将分层贫燃技术与甲醇相结合，为实现直喷式火花点火（DISI）发动机的高效率和低排放提供了一条可行之路。这项研究比较了甲醇/汽油燃料在 DISI 发动机上的分层和均匀分层贫燃特性。研究了两种分层贫燃策略下的燃烧和排放特性。结果表明，与双喷射分层稀薄燃烧（DISL）相比，单喷射分层稀薄燃烧（SISL）的燃烧更及时，而且随着过量空气比率的增加，燃烧恶化的速度更慢。在使用 M20 燃料和 SISL 时，对空气稀释的容忍度更高。在过量空气比相同的情况下，SISL 可提高最大缸内压力和燃烧温度，但降低排气温度。使用 M40 燃料时，SISL 的经济区为 λ = 1.3-1.6，而 DISL 的经济区为 λ = 1.1-1.3。当 λ 低于 1.5 时，SISL 的碳氢化合物（HC）排放量较高，但氮氧化物（NOx）排放量较低。然而，当 λ 超过 1.5 时，DISL 的碳氢化合物排放量急剧增加，而氮氧化物排放量则显著减少。SISL 的颗粒浓度至少比 DISL 高一个数量级，颗粒大小分布形成了一条以堆积模式颗粒为中心的单峰曲线。相反，DISL 则呈现准双峰分布。

A macro-thermobalance (macro-TGA) was applied to investigate the steam co-gasification characteristics of the chars produced from Huainan coal (HN), two types of biomasses, sawdust (SD) and wheat straw (WS), and coal-biomass blends at 900–1200 °C under rapid heating conditions. The gasification reaction kinetics were determined by the homogeneous reaction model (VM), shrinking core model (SCM) and random pore model (RPM), and the optimal model was selected by deviation calculation. The results show that the char gasification reactivity increased with the increase of temperature. The promotion effect of biomass semi-coke on coal char mainly occurred in the stage when the carbon conversion rate was greater than 0.5, which is mainly attributed to the migration of active AAEMs to the surface of coal char to catalyze the gasification reaction in the later stage. However, with the increase in temperature, this promoting effect is weakened due to the increasing influence of mass transfer effects over chemical rate control, and increased volatilization of the inorganic species. The RPM model is suitable for describing the coal char gasification process, while the SCM was the model that best fitted the biomass semi-coke and coal/biomass blends, which elucidates the kinetic mechanisms governing the gasification process.

在900-1200 ℃快速加热条件下，应用宏观热平衡（macro-TGA）研究了淮南煤（HN）、锯末（SD）和小麦秸秆（WS）两种生物质以及煤-生物质混合物制得的焦炭的蒸汽共气化特性。通过均相反应模型（VM）、收缩核心模型（SCM）和随机孔模型（RPM）确定了气化反应动力学，并通过偏差计算选择了最优模型。结果表明，炭气化反应活性随温度的升高而增加。生物质半焦对煤炭的促进作用主要发生在碳转化率大于 0.5 的阶段，这主要是由于活性 AAEMs 迁移到煤炭表面催化了后期的气化反应。然而，随着温度的升高，这种促进作用会减弱，原因是传质效应对化学速率控制的影响增大，以及无机物挥发增加。RPM 模型适用于描述煤炭炭化过程，而 SCM 是最适合生物质半焦和煤/生物质混合物的模型，它阐明了气化过程的动力学机制。
