Abstract ：
In the present work, the selective hydrodeoxygenation (HDO) performance of stearic acid over in situ MoS2 catalysts produced from various Mo precursors was evaluated. Notably, the in situ MoS2 catalyst generated from [N-8881](2)MoO4-a Mo-based ionic liquid (IL) with oil-soluble property-achieves up to 99.9% of stearic acid conversion with the HDO product octadecane yield of 97.5% at 300 degrees C, 8 MPa, and 6 h. The activity of [N-8881](2)MoO4 for catalyzing the selective HDO reaction is much better than commercial precursors like Mo(CO)(6) and (NH4)(6)Mo7O24. The in situ MoS2 catalysts were thoroughly characterized and analyzed to elucidate the experimental results. Moreover, the reaction pathway of stearic acid was proposed according to the product distribution, and the relative kinetic parameters were also calculated and discussed. The results indicate that applying Mo-based IL as the precursor to generate in situ MoS2 catalyst for the selective HDO of biolipids is highly interesting and desired.

Abstract ：
利用风光新能源,寻找沿海受端电力系统较低成本的减碳路径,是中国"碳达峰·碳中和"目标实现的核心挑战之一.通过分析氢氨储能与现有储能类型(如电化学、压缩空气等)的技术经济差异,建立了时序减碳约束下含耦合火电掺烧的氢氨储能的电力系统多年拓展规划模型,并探讨其在电力系统中实现较低成本减碳的技术经济可行性.算例选取广东电网实际数据进行研究.结果表明,在日益严格的碳减排约束下,需要逐步通过新增风光储、"以气代煤"的火电规划模式、新增氢氨储能(包含气电掺氢、煤电掺氨和氨分解等方式)等技术路径实现减碳目标.对比仅通过锂电池调峰的减碳模式,通过引入耦合火电掺烧的氢氨储能技术,可以避免超配大量的风光储容量,显著降低了风光弃电率.这不仅实现了资源的集约利用,而且通过复用存量火电基础设施,进一步降低了氢氨储能减碳成本.因此,利用氢氨储能技术进行电力系统减碳是一条可规模化且较为经济可行的减碳路径.

Abstract ：
The efficient utilization of hydrogen resources in H2S has aroused great attention in both resource utilization and environmental protection. Using H2S as a hydrogen resource donor for the reduction of nitrobenzene to aniline could be an effective method to replace H2. Herein, we fabricated the porous flower-like CoNi-LDO catalyst through facile morphology control engineering, which utilizes DMF as an intercalating agent to influence the structure and properties. Endowed with abundant electron-rich oxygen vacancies and enhanced basic sites capacity, the as-designed CoNi-D catalyst exhibits considerable aniline selectivity (96 %) and high catalytic stability over seven cycles at 110 degrees C. The potential single H-induced dissociation pathway for the reduction of nitrobenzene to aniline by H2S was explored using in situ FT-IR analysis. The present study could provide a feasible strategy for designing catalysts for the high-value utilization of H2S.

Abstract ：
氨部分预分解是改善氨的燃烧性能的有效手段,但对于氨预分解条件的影响仍缺乏系统的研究.该文针对基于氨预分解策略的氨扩散燃烧装置开展数值模拟研究,以分析氨预分解比例、当量比和氨分解余热对燃烧及污染物排放特性的影响.结果表明,随着氨预分解比例提高,火焰温度提高,火焰高温区更靠近喷嘴,NOx排放量下降;NO排放在NOx中占主导,并随着当量比的提高先增大后减小;N2O排放主要发生在低氨预分解比例、低当量比条件下,在氨预分解比例达到50％后基本消失;利用氨分解余热预热燃料有助于稳定燃烧,并在氨预分解比例不超过30％时,明显减少氨泄漏而未增加NOx排放.研究表明,提高氨预分解比例和当量比能有效改善氨燃烧及污染物排放特性,而在小比例氨预分解条件下应充分利用氨分解的余热.

Abstract ：
Developing catalysts enabling reactive separation is a promising strategy to enhance reaction and separation efficiency of esterification processes. Herein, we designed a class of hybrid catalysts with p-toluenesulfonic acid (PTSA) as main catalyst, and hydrogensulfate ILs as support catalyst and extractant. Using the designed catalysts for methyl esterification of long-chain fatty acids, phase splitting can occur, resulting in ester-rich and catalyst-rich phases. Under optimal conditions, the conversion of palmitic acid (PA) gives methyl palmitate (MP) yield of 98.2 % in 3 hat 348.2 K. The catalysts are also applicable for effective conversion of other long-chain fatty acids and can be facilely recycled through liquid-liquid separation without loss of activity. COSMOtherm and Gaussian calculations were performed to rationalize the reactive separation behavior of the designed catalysts. The kinetic and thermodynamic properties of the esterification reaction were also examined using pseudo-homogeneous (PH) model with non-ideality corrections.

Abstract ：
Ammonia is a carbon-free energy carrier with 17.6 wt% hydrogen content. The design of an efficient and compact ammonia decomposition reactor based on low-temperature catalysts is the key to realizing industrial hydrogen production from ammonia. In this work, a multiscale model was developed by bridging the particle-scale characteristics of catalysts and reactor performances, to fully comprehend the ammonia decomposition process. The effects of catalyst porosity and pore diameters on the reactor size, precious metal loading, and the profile of temperature and heat flux were systematically evaluated. An improved reactor design was further proposed by applying the segmented reactor packed with two-stage egg-shell-type low-temperature catalysts, which decreased the precious metal usage by 61.6% and the temperature drop by 42.9 K. This segmentation strategy balanced the reaction rate and heat flux, indicating a significant potential in highly efficient, economical, and reliable hydrogen production from ammonia.

Abstract ：
The water gas shift reaction is an important procedure in high-purity hydrogen production, and achieving high CO conversion in one single reactor is a key optimization objective. This work has developed a novel radial flow fixed-bed reactor for water gas shift reaction with integrated variable heat exchange and numerically investigated the system optimization concepts. The continuous heat removal from the catalyst bed has been proven to fully improve CO conversion at a lower H2O/CO molar ratio. The heat transfer rate distribution can also be flexibly adjusted to ensure sufficiently high and low temperatures in the early and late stages of the reaction, respectively, for a higher conversion. With sufficient coolant, low-temperature and high-temperature catalysts for water gas shift reaction can be combined in one reactor to increase CO conversion to over 98%, and the delayed heat removal configuration can achieve the highest CO conversion (98.50%) with the least proportion of low-temperature catalysts (9.2%).

Abstract ：
当液氨管道处于事故泄漏、停输超压或计划维护等情况时,可采用泄放的方式对管内液氨进行泄压回收.由于氨的高体积膨胀性,其泄放过程的节流效应会导致管内温度骤降,加剧管道受冷收缩和脆性断裂的风险.针对目前液氨管道泄放特性研究不足,参考国内外相关设计和运行参数,建立液氨管道泄放仿真模型,探讨管长、管径和操作条件(温度、压力)影响下的泄放特征参数发展规律.研究结果表明:随着管道长度减小,泄放初期管内压降和温降增大,泄放过程压力和温度随时间下降幅度增加;随着管径减小,泄放口初始压力和温度下降幅度增大,泄放时间和泄放最低温度减小;管道运行压力对整体泄放过程影响较小;管道运行温度越低,泄放口初始温降越大,泄放所需时间越长.研究成果将为液氨管道紧急泄放的安全控制和应急方案的制定提供重要依据.

Abstract ：
氨作为高效的储氢载体,具有替代化石燃料能源的巨大潜力.利用成品油管道增输液氨,可充分利用管道运能,节约输送成本.液氨-成品油混合体系的相平衡问题对于管输工艺具有重要意义,此外减压过程会引起更为复杂的相变问题.针对液氨-成品油混合体系进行实验研究,初步阐述了氨/油(体积比)和含水率对液氨-成品油混合体系相平衡和减压相变的影响规律,得到了液氨-成品油混合体系的相平衡压力,揭示了液氨-成品油混合体系减压过程的相变现象.研究发现,在0～30℃,氨-油混合体系的平衡蒸气压小于两种纯组分的饱和蒸气压,而在-2～0℃大于纯液氨的饱和蒸气压,并在氨/油(体积比)为70∶30时达到最大值.同时水分的存在会降低氨-油混合体系的平衡蒸气压.氨-油无水混合体系在减压过程中会产生气泡,压力越低气泡增多,发泡行为越剧烈.含水液氨-成品油混合体系在减压过程中会产生液滴群,并慢慢变大且聚并,在减压结束后聚并形成大液滴留在底部.上述研究成果对成品油管道增输液氨技术发展和应用具有重要的理论指导意义.

Abstract ：
Direct ammonia solid oxide fuel cells (DA-SOFCs) have triggered great interest due to their efficient power generation from ammonia directly. However, the compatible match of ammonia decomposition and electrooxidation in the DA-SOFCs remains greatly challenging due to their endo/exothermic properties. Herein, multi-sizes tubular DA-SOFCs were systematically investigated for performance evaluation of power output and ammonia decomposition. Accordingly, a multi-scale electro-thermo model for tubular DA-SOFC was established to intensify the synergy between complex physical-chemical processes and geometry. With the combination of experimental work and simulations, the effects of operating conditions and geometry were comprehensively evaluated. Significantly, the rates of ammonia decomposition and electrooxidation could be effectively matched through the optimization of operating conditions. The geometric design further enables the temperature-zoning of the two processes, competently enhancing the thermal coupling between them. Conclusively, the correlation equations linking the operating conditions, geometry and electrical efficiency were proposed for the scaling-up of tubular DA-SOFCs unit. The tubular DA-SOFC achieves 3.5 W with 60% electrical efficiency, and performed a satisfactory stability for over 330 h. This study provides guidance for oriented design of tubular DA-SOFCs with high electrical efficiency.
