The present study explores the concentrated solar-driven pyrolysis of walnut shells to characterize the product distribution, physicochemical structural evolution, and energy flow. The experiments were conducted using a custom-built Confocal Elliptical-Streamline Concentrating Photothermal (CESCP) system, which implements a furnace lamp with a spectral output closely approximating natural sunlight. This setup provides a controlled simulation of genuine high-flux solar radiation and achieves an ultra-fast heating rate of 1000 °C/min. Across the temperature range of 500–1000 °C, the gas yield was notably high and increased significantly from 13.4% to 54.3%, among which syngas (H₂ + CO) exhibited the most substantial increase from 40.99 vol% to 70.5 vol%. For solid phase products, as the pyrolysis reaction proceeded, the specific surface area significantly increased by 314 times from 0.354 m²/g to 111.459 m²/g, the amorphous carbon progressively transformed into defective polycyclic aromatic hydrocarbons, and the oxygen-containing functional groups (such as hydroxyl and C-O bonds) exhibited higher activity. Crucially, at the pyrolysis temperature of 1000 °C, the sum of the higher heating value and the latent heat of vaporization of the products reached 17,207 J, representing an increase of 199 J compared to the raw biomass material. This data provides direct quantitative evidence for the storage of solar energy in the form of chemical energy. The findings of this study can serve as a fundamental theoretical reference for research on solar-thermal conversion and storage mechanisms under intense radiative heating conditions.

本研究对核桃壳的太阳能集中热解进行了研究，表征了产物分布、物理化学结构演化和能量流。实验使用定制的共聚焦椭圆-流线聚光光热（CESCP）系统进行，该系统实现了光谱输出接近自然阳光的炉灯。该装置提供了真正的高通量太阳辐射的受控模拟，并实现了1000°C/min的超快加热速率。在500 ~ 1000℃的温度范围内，产气率从13.4%显著提高到54.3%，其中合成气（H2 + CO）产气率从40.99 vol%提高到70.5 vol%，增幅最大。固相产物中，随着热解反应的进行，比表面积从0.354 m2/g显著增加到111.459 m2/g，增加了314倍，无定形碳逐渐转化为缺陷多环芳烃，含氧官能团（如羟基和C-O键）表现出更高的活性。关键是，在热解温度为1000℃时，产物的高热值与汽化潜热之和达到17,207 J，比生物质原料增加了199 J。这一数据为太阳能以化学能的形式储存提供了直接的定量证据。本研究结果可为强辐射加热条件下的光热转换与蓄热机理研究提供基础理论参考。

Selective hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) is a benchmark reaction in lignocellulosic biomass valorization. In this study, we investigated the structure–activity relationships of Co catalysts supported on γ-Al₂O₃, MgO, and MgAl. Catalysts were synthesized via incipient wetness impregnation and characterized using ex-situ and in-situ techniques to elucidate structural properties. The oxide supports exerted a strong influence on Co dispersion, oxidation state, and acid–base characteristics. Co/Al₂O₃ provided high surface area and well-dispersed Co⁰ species, whereas Co/MgO stabilized larger, partially oxidized particles of low reducibility. In contrast, Co/MgAl exhibited an intermediate state of predominantly Co⁰ with minor Co²⁺ species, accompanied by high H₂ adsorption and suitable acidity and basicity. Under 30 bar H₂ in 2-propanol, Co/MgAl achieved 100 % LA conversion and 86 % GVL yield at 120 °C within 2 h, outperforming Co/MgO and Co/Al₂O₃. Isotopic labeling with D₂O and 2-PrOD₈ confirmed dual hydrogenation pathways via direct H₂ activation and solvent-mediated transfer hydrogenation. Regeneration–recycling tests further demonstrated the superior stability of Co/MgAl, retaining 80 % GVL yield after four cycles with minimal Co leaching. These findings emphasize the role of support-induced structural modulation in LA hydrogenation, establishing Co/MgAl as a robust platform for scalable LA-to-GVL upgrading.

乙酰丙酸（LA）选择性加氢生成γ-戊内酯（GVL）是木质纤维素生物质增值的一个基准反应。在这项研究中，我们研究了γ-Al₂O₃、MgO和MgAl负载的Co催化剂的构效关系。采用初湿浸渍法制备了催化剂，并用原位和非原位技术对催化剂进行了表征。氧化物载体对钴的分散、氧化态和酸碱特性有很大的影响。Co/Al₂O₃提供了高表面积和分散良好的Co0物种，而Co/MgO稳定了较大的、部分氧化的低还原性颗粒。Co/MgAl表现为以Co0为主的中间态，Co2+含量较少，具有较高的H₂吸附性和适宜的酸碱度。在2-丙醇中，在30 bar H₂条件下，Co/MgAl在120°C下，在2 H内实现了100%的LA转化率和86%的GVL收率，优于Co/MgO和Co/Al₂O₃。用D₂O和2-PrOD₈同位素标记确定了通过直接H₂活化和溶剂介导的转移氢化的双重氢化途径。再生-循环试验进一步证明了Co/MgAl的优越稳定性，在4个循环后保持80%的GVL产率，且Co浸出率最低。这些发现强调了支持诱导的结构调制在LA加氢中的作用，建立了Co/MgAl作为可扩展的LA到gvl升级的强大平台。

Plastic pollution has escalated into a dire threat to the environment, prompting an urgent need for improved plastic waste management. Pyrolysis is among the fastest-developing technologies for converting certain waste plastics into fuels and chemicals. In this work, we studied fluorinated γ-alumina as a catalyst for the two plastics with the highest global production volumes: high-density polyethylene (HDPE) and polypropylene (PP). Catalysts with varying fluorine loadings (0, 2, 4, 8, and 20 wt%) were readily prepared by partial fluorination of γ-alumina with aqueous NH₄F. Pyrolysis experiments were conducted in a stainless-steel batch reactor at 420 °C for HDPE and 370 °C for PP. The resulting crude pyrolysis oils were separated by distillation into two distillate fractions (bp. RT–200 °C and 200–300 °C), and the bottom product. Compared to thermal pyrolysis, catalytic pyrolysis promoted more extensive fragmentation and significantly increased volatile yields (gases and distillates), reaching 84% for HDPE and over 90% for PP. It also reduced the minimum temperatures required to obtain fully liquid crude pyrolysis oils, from 420 °C to 380 °C for HDPE and from 370 °C to 340 °C for PP.

塑料污染已经升级为对环境的严重威胁，迫切需要改善塑料废物管理。热解是将某些废塑料转化为燃料和化学品的发展最快的技术之一。在这项工作中，我们研究了氟化γ-氧化铝作为全球产量最高的两种塑料的催化剂：高密度聚乙烯（HDPE）和聚丙烯（PP）。不同氟负载（0、2、4、8和20 wt%）的催化剂很容易通过用NH₄F水溶液部分氟化γ-氧化铝制备。在不锈钢间歇式反应器中对HDPE和PP分别在420°C和370°C条件下进行热解实验，得到的粗热解油经精馏分离为两个馏分(bp；RT-200℃和200-300℃)，以及底部产品。与热热解相比，催化热解促进了更广泛的裂解，显著提高了挥发物收率（气体和馏分），HDPE达到84%，PP超过90%。它还降低了获得全液态粗热解油所需的最低温度，HDPE从420℃降至380℃，PP从370℃降至340℃。

Hydroisomerization plays a significant role in improving the low-temperature fluidity of diesel fuel, producing gasoline with a high-octane number, and lowering the pour point of lubricating oil. Therefore, the development of hydroisomerization catalysts is crucial. Herein, two steps are utilized to this end for synthesizing a hierarchical ZSM-48 zeolite (Z48–0.2CA) continuously: the growth modifier cetyltrimethylammonium bromide (CTAB) is utilized first to limit the growth of ZSM-48 crystals and introduce rich intercrystalline mesopores. Then, the nano-ZSM-48 crystals are treated with citric acid to form intracrystalline mesopores. Furthermore, the acidity of the synthesized Z48–0.2CA is effectively reduced. The test of the catalytic performance of n-hexadecane hydroisomerization over the Pd-loaded Pd/Z48-CA bifunctional catalysts demonstrates that the Pd/Z48–0.2CA catalysts prepared with a CTAB/Al mole ratio of 0.2 and treated with citric acid has the highest iso‐hexadecane yield of 68.8 %, which is 12.0 % greater at lower reaction temperature in contrast to the conventional microporous Pd/Z48 catalyst because of the improved diffusion of hydrocarbons in the channel of the zeolite and the increased C_Pd/C_H+ value. Therefore, the use of a growth modifier and acid treatment for the synthesis of hierarchical zeolite effectively enhances the catalytic performance of bifunctional catalysts.

加氢异构化对提高柴油低温流动性、生产高辛烷值汽油和降低润滑油的倾点具有重要作用。因此，开发加氢异构化催化剂至关重要。本文通过两个步骤连续合成了分级ZSM-48分子筛（Z48-0.2CA）：首先利用生长调节剂十六烷基三甲基溴化铵（CTAB）限制ZSM-48晶体的生长，引入丰富的晶间介孔。然后，用柠檬酸处理纳米zsm -48晶体，形成晶内介孔。此外，合成的Z48-0.2CA的酸度也得到了有效降低。负载Pd的Pd/Z48-CA双功能催化剂催化正十六烷加氢异构化的性能测试表明，CTAB/Al摩尔比为0.2、柠檬酸处理的Pd/ Z48-0.2CA催化剂的异十六烷收率最高，达到68.8%；在较低的反应温度下，与传统的微孔Pd/Z48催化剂相比，CPd/CH+值提高了12.0%，这是由于沸石通道中碳氢化合物的扩散得到改善，CPd/CH+值提高。因此，采用生长调节剂和酸处理合成分级沸石有效地提高了双功能催化剂的催化性能。

The steel industry is a pillar of China's national economy, with energy consumption accounting for more than 10 % of the national total. As a key stage in steel production, the sintering process contributes about 8 % of total energy use. Under the dual carbon goals, improving energy efficiency in sintering has become an urgent challenge. However, existing prediction models often exhibit errors exceeding 10 %, limiting energy-saving research. To address this issue, this study develops a sintering energy consumption model using one year of continuous production data from a steel plant, combining mechanism analysis with a genetic algorithm–optimized long short-term memory network (GA-LSTM). The model achieved a prediction error below 5 % over 30 consecutive days. In addition, an energy diagnostic framework based on the analytic hierarchy process was proposed, analyzing influencing factors across three levels: “energy consumption–energy carriers–operational parameters.” Results show that solid fuel is the dominant energy carrier, contributing 73.36 %, while parameters such as sinter basicity strongly affect fuel use. Proper adjustment can reduce solid fuel consumption by 2.6 kg/t. Considering process stability and parameter coupling, two optimization strategies—uncorrected and corrected—were proposed, reducing energy consumption by 1.85 kgce/t and 1.25 kgce/t, respectively.

钢铁行业是中国国民经济的支柱产业，能源消耗占全国总量的10%以上。烧结是钢铁生产的关键环节，其能耗约占总能耗的8%。在双碳目标下，提高烧结能源效率已成为迫切的挑战。然而，现有的预测模型往往误差超过10%，限制了节能研究。为了解决这一问题，本研究利用某钢厂一年的连续生产数据，将机制分析与遗传算法优化的长短期记忆网络（GA-LSTM）相结合，建立了烧结能耗模型。该模型在连续30天内的预测误差低于5%。此外，提出了基于层次分析法的能源诊断框架，从“能源消耗-能源载体-运行参数”三个层面分析影响因素。结果表明，固体燃料是主要的能量载体，贡献了73.36%，而烧结碱度等参数对燃料的使用影响较大。适当调整可减少2.6 kg/t的固体燃料消耗。考虑工艺稳定性和参数耦合，提出了未校正和校正两种优化策略，能耗分别降低1.85 kgce/t和1.25 kgce/t。

The reliance on fossil fuels for energy production poses significant environmental challenges, necessitating the need for sustainable energy alternatives. Dimethyl ether (DME), with its non-toxic and biodegradable properties, has emerged as a promising substitute to conventional fuels, offering advantages over both liquefied petroleum gas (LPG) and diesel fuel. This review highlights recent developments in DME synthesis pathways, focusing on direct and indirect CO₂ hydrogenation routes. Particular attention is given to innovative bifunctional catalyst developments that integrate methanol synthesis and dehydration capabilities in a single system. The study systematically evaluates catalyst design challenges, specifically addressing metal-acid functionality optimization and long-term stability considerations. Through detailed examination of operating parameters—temperature, pressure, and space velocity—we identify critical DME process intensification opportunities for researchers in the field for further development.

Dissociated methanol gas (DMG) is a hydrogen-rich mixture produced from methanol using engine exhaust heat. In this study, a diesel/DMG dual-fuel engine was developed to investigate the effects of DMG blending on performance under typical operating conditions and to explore the potential of exhaust-heat-driven methanol decomposition for improving efficiency and reducing fuel cost. DMG generated in a methanol decomposition reactor was introduced into the cylinder to co-combust with diesel. Results show that at a 20 % substitution ratio, the engine's thermal efficiency increased by (1.08 ± 0.08)% and fuel costs decreased by (10.47 ± 0.25)%. The improvement was statistically significant (p < 0.05). DMG addition led to higher peak cylinder pressure, pressure rise rate, and heat release rate, along with advanced combustion phasing, a shorter combustion duration, and slightly increased cycle-to-cycle variation. Regarding emissions, NOx increased with higher substitution ratios, while soot exhibited a slight rise. HC emissions first decreased and then increased marginally, whereas CO emissions showed a small increase. Blending DMG with diesel not only recycles exhaust heat but also modifies combustion characteristics, improving engine efficiency and lowering operational costs. This method presents a competitive and promising pathway for the efficient utilization of future clean energy.

解离甲醇气体（DMG）是一种由甲醇利用发动机尾气产生的富氢混合物。在本研究中，开发了一台柴油/DMG双燃料发动机，以研究DMG混合对典型工况下性能的影响，并探索废热驱动的甲醇分解在提高效率和降低燃料成本方面的潜力。将甲醇分解反应器生成的DMG引入汽缸与柴油共燃。结果表明，当替代率为20%时，发动机热效率提高（1.08±0.08）%，燃油成本降低（10.47±0.25）%。改善有统计学意义（p < 0.05）。DMG的加入导致了更高的峰值气缸压力、压力上升率和热释放率，同时燃烧阶段提前，燃烧持续时间缩短，循环间变化略有增加。在排放量方面，随着替代率的增加，NOx增加，而烟尘略有增加。HC排放量先减少后略有增加，而CO排放量则略有增加。将DMG与柴油混合不仅可以回收废气热量，还可以改变燃烧特性，提高发动机效率并降低运行成本。该方法为未来清洁能源的高效利用提供了一条具有竞争力和前景的途径。

Against the backdrop of global energy transition and sustainable development, biodiesel has emerged as a promising renewable and clean energy source, with technological innovation and optimization in its production attracting significant attention. The utilization of non-edible oils (e.g., waste oils) as feedstocks and biomass-derived catalysts for large-scale biodiesel production represents an effective approach to reducing production costs while addressing food safety and environmental concerns. This review systematically examines recent advancements in two critical areas: the application of second-generation non-edible oils, particularly waste cooking oils, as biodiesel feedstocks, and the development of catalysts derived from renewable resources and mineral carriers. The proposed strategy of integrating novel catalysts with waste oil feedstocks not only achieves efficient resource utilization of waste materials and cost reduction but also mitigates environmental burdens. Future research should focus on in-depth investigation of the structure-activity relationships of biomass-derived catalysts to optimize their performance, as well as the deep integration of catalyst design with biomass waste utilization. These efforts will be pivotal in advancing the sustainable development of the biodiesel industry.

在全球能源转型和可持续发展的背景下，生物柴油作为一种前景广阔的可再生清洁能源，其生产技术创新和优化备受关注。利用非食用油（如废油）作为大规模生物柴油生产的原料和生物质衍生催化剂是降低生产成本同时解决食品安全和环境问题的有效方法。本文系统地综述了两个关键领域的最新进展：第二代非食用油（特别是废弃食用油）作为生物柴油原料的应用，以及从可再生资源和矿物载体中提取的催化剂的开发。提出的将新型催化剂与废油原料相结合的策略，不仅实现了废油资源的高效利用和成本的降低，而且减轻了环境负担。未来的研究应着眼于深入研究生物质衍生催化剂的构效关系，优化其性能，并将催化剂设计与生物质废弃物利用深度融合。这些努力对推动生物柴油产业的可持续发展至关重要。

To reduce emissions from waste management, chemical looping combustion can be applied to waste-to-energy processes for carbon capture. This study presents experimental results testing chemical looping combustion of waste-derived fuel at pilot-scale (150 kW_th) using ilmenite as oxygen carrier. For comparison, tests with biomass were conducted under similar conditions. Six operating periods were analyzed focusing on hydrodynamics, gas-phase composition including heavier hydrocarbons such as benzene, carbon distribution, and energy recovery. Additionally, the performance indicators oxygen demand and carbon capture efficiency are determined. The results demonstrate the technical feasibility of chemical looping combustion with waste as fuel. Stable operation was achieved in all cases, including a modified configuration for simplified scale-up without a secondary circulation pathway coupling the bottom of both reactors. While reactor hydrodynamics remained consistent, disabling the bottom-loop led to lower temperatures and significantly reduced fuel conversion. Compared to biomass, waste yielded less residual carbon monoxide and hydrogen and higher concentrations of heavier hydrocarbons like ethylene and benzene in the fuel reactor off-gas, particularly at lower temperatures. Carbon slip was similar for both fuels with capture efficiencies ranging from 92 % to 96 %. Oxygen demands were determined above 30 % with slightly lower values observed for waste compared to biomass. Up to 60 % of the fuel chemical energy remained in combustible off-gas species, indicating substantial incomplete conversion but also potential for gasification-oriented applications. This highlights the need for further optimization of reactor design, oxygen carrier materials, and operating conditions before large-scale deployment in future waste management systems.

为了减少废物管理产生的排放，可以将化学循环燃烧应用于废物转化为能源的过程，以实现碳捕获。本研究以钛铁矿为载氧剂，在中试规模（150千瓦时）进行了废弃物燃料化学循环燃烧试验。为了比较，在相似的条件下进行了生物质试验。分析了六个操作周期，重点是流体动力学、气相组成（包括较重的碳氢化合物，如苯）、碳分布和能量回收。此外，还确定了性能指标需氧量和碳捕获效率。结果表明，利用废弃物作为燃料进行化学循环燃烧技术是可行的。在所有情况下都实现了稳定运行，包括简化的放大配置，而没有将两个反应器底部连接在一起的二次循环通道。虽然反应堆流体动力学保持一致，但关闭底回路导致温度降低，燃料转化率显著降低。与生物质相比，废物在燃料反应堆废气中产生的残余一氧化碳和氢气较少，而乙烯和苯等较重碳氢化合物的浓度较高，特别是在较低温度下。两种燃料的碳滑脱相似，捕集效率在92%到96%之间。需氧量高于30%，与生物质相比，废物的需氧量略低。高达60%的燃料化学能仍然存在于可燃废气中，这表明大量的不完全转化，但也有气化导向应用的潜力。这凸显了在未来的废物管理系统中大规模部署之前，需要进一步优化反应器设计、载氧材料和操作条件。

This study investigates the GICO (Gasification Integrated with CO₂ Capture and Conversion) concept, an innovative biogenic waste treatment scheme combining hydrothermal carbonization (HTC), sorption-enhanced gasification (SEG), hot gas cleaning (HGC), plasma-assisted CO₂ conversion, methanol synthesis, and solid oxide fuel cell (SOFC). Experimental campaigns were carried out on winery residues as representative wet biomass. HTC produced hydrochar with improved fuel properties (C/O ratio increased to 61 %) that was then processed in SEG tests, yielding hydrogen-rich syngas (75.8 vol%) with a cold gas efficiency (CGE) of 75.5 %. These data were used to calibrate an Aspen Plus model of a pilot-scale plant treating 550 kg/h of wet biomass. The model successfully reproduced experimental results enabling a methanol synthesis of 66 kg/h (CGE 42.4 %). The SOFC subsystem generated 259 kWh of electricity and 215 kWh of recoverable heat, expanding the product distribution. Overall, the process efficiency reached 32.4 % limited by the process energy demand, mainly due to the plasma reactor, highlighting the potential of a reduced-plasma-feed configuration achieving 39.7 % efficiency. Preliminary heat recovery strategies reduced external requirements by 88.5 % and increased the overall efficiency to 38.9 %, and the carbon utilization at 84.5 % highlighting the crucial role of thermal integration in optimizing the GICO process.

本研究探讨了GICO （Gasification Integrated with CO₂Capture and Conversion）概念，这是一种结合水热碳化（HTC）、吸附强化气化（SEG）、热气体净化（HGC）、等离子辅助CO₂转化、甲醇合成和固体氧化物燃料电池（SOFC）的创新生物源废物处理方案。以酒窖残渣为代表的湿生物质为研究对象进行了试验。HTC生产的氢炭具有改进的燃料性能（C/O比增加到61%），然后在SEG试验中进行处理，产生富氢合成气（75.8 vol%），冷气效率（CGE）为75.5%。这些数据被用来校准一个Aspen Plus模型，该模型是一个中试规模的植物，处理550 kg/h的湿生物质。该模型成功地再现了实验结果，使甲醇合成达到66 kg/h （CGE 42.4%）。SOFC子系统产生了259千瓦时的电力和215千瓦时的可回收热，扩大了产品分布。总体而言，工艺效率达到32.4%，主要受过程能量需求的限制，主要是由于等离子体反应器，突出了减少等离子体供给配置的潜力，达到39.7%的效率。初步的热回收策略减少了88.5%的外部需求，将整体效率提高到38.9%，碳利用率达到84.5%，突出了热集成在优化GICO过程中的关键作用。
