This reaction is of great significance in addressing climate change, reducing greenhouse gas emissions, and achieving carbon dioxide recycling. In the reaction of carbon dioxide hydrogenation to methanol, efficient and stable catalyst is one of the important factors for the efficient conversion of carbon dioxide to methanol. However, the currently reported catalysts basically need to play a catalytic role at higher temperatures and pressures. Therefore, the development of a catalyst that can maintain high activity at lower temperatures and pressures remains an urgent challenge. In this study, In₂O₃/ZnO heterostructure catalysts were prepared by water bath combined with subsequent Solvothermal method. At 250 °C and 2 MPa, the CO₂ conversion of In₂O₃/ZnO-2 catalyst was 13.5 %, the methanol selectivity was 83.3 %, and the methanol space-time yield (STY) was 0.437 g·g_cat⁻¹·h⁻¹, which was 4.8 times and 2.9 times that of pure In₂O₃ (0.091 g·g_cat⁻¹·h⁻¹) and CP-In₂O₃/ZnO (0.151 g·g_cat⁻¹·h⁻¹), respectively. The formation of In₂O₃/ZnO heterostructure, large specific surface area and more exposed active sites, as well as abundant oxygen vacancies in the material, promote the good catalytic performance of In₂O₃/ZnO-2 catalyst. It is expected that this novel In₂O₃/ZnO heterostructure catalyst will provide new ideas and inspiration for the design and development of bimetallic oxide catalysts with high activity and selectivity for carbon dioxide hydrogenation to methanol at lower temperatures and pressures.</div></div>","PeriodicalId":17287,"journal":{"name":"Journal of The Energy Institute","volume":"120 ","pages":"Article 102045"},"PeriodicalIF":5.6,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluation was conducted at volumetric concentrations of 5 % (MAB5) and 10 % (MAB10). The results indicated a substantial reduction in carbon monoxide (CO) emissions by 76.79 % for MAB5 and 66.39 % for MAB10, as well as a decrease in hydrocarbon (HC) emissions by 21.39 % and 35.39 %, respectively. Carbon dioxide (CO₂) emissions were also reduced by 15.29 % for MAB5 and 9.76 % for MAB10, suggesting an improvement in combustion efficiency. However, an increase in nitrogen oxides (NO_x) emissions was observed, likely due to higher peak combustion temperatures. Elevated oxygen (O₂) levels in the exhaust were noted, reflecting alterations in in-cylinder oxygen dynamics and combustion stoichiometry. Performance analysis revealed that MAB use resulted in higher brake-specific fuel consumption (BSFC) and lower thermal efficiency, with reductions of 7.69 % and 9.93 % for MAB5 and MAB10, respectively, attributable to the lower energy density of MAB relative to gasoline. A decrease in exhaust gas temperature was observed, suggesting a complex interaction of energy release and heat transfer processes. Despite the reduction in emissions, the increase in NOx formation highlights the intensification of combustion phases and greater thermal stress within the engine cylinder. The findings suggest that MAB, as a hydrogen-enriched fuel additive, offers notable benefits in emission reduction, but presents challenges such as reduced performance efficiency and increased thermal management requirements. These results underscore the need for optimizing additive formulations and operational parameters to balance the emission reduction potential with performance efficiency in gasoline engine applications.</div></div>","PeriodicalId":17287,"journal":{"name":"Journal of The Energy Institute","volume":"120 ","pages":"Article 102044"},"PeriodicalIF":5.6,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novel burnout prediction model (simulating the combustion of the chars produced) is based on composite burnout profiles for different char types and is the first burnout prediction model which uses char morphology data to quantitatively predict burnout. It provides a rapid burnout comparison tool for power generators by quantifying the carbon loss during an iterative process, where the char material is progressively ‘burning’ from the outside inwards. Finally, by combining the milling and burnout metricises, it is possible to predict milling requirements for a desired burnout performance.

The thermogravimetric (TG) curve indicated that the pyrolysis of polyester/cotton began at 255.1 °C and ended at 471.7 °C.

The process aims to improve biocrude properties than other traditional processes while also reducing energy consumption by utilization of ScCO₂. Acetone can theoretically be used in conjunction with the NILE process as a solvent or co-solvent with supercritical CO₂.

The findings revealed that nitrogen-containing species not only effectively inhibit the cyclization process of PAHs but also promote the formation of long branched carbon chains. This regulatory mechanism alters the structural characteristics of PAHs, thereby inhibiting the growth of PAHs. Specifically, during the mass growth of clusters, the nitrogen-containing radicals react with propargyl radical (C₃H₃) to generate nitrogen-containing hydrocarbon precursors that actively participate in clusters formation, facilitating the transition from small clusters to larger clusters, which consequently shortens the growth time of clusters. Moreover, the introduction of nitrogen-containing radicals leads to a 50 % increase in the total number of carbon atoms in C₁₆₊ clusters relative to the C₃H₃ system, while the number of clusters dramatically decreases by 58.3 %. Structural analysis indicates that the total number of rings in PAHs within the nitrogen-containing species system decreases by as much as 80.8 % compared to the C₃H₃ system, and the PAH growth inhibition factor increases by as much as 5.3 times. This suggests that nitrogen-containing species have a significant inhibition effect on the growth of PAHs. Additionally, molecular trajectory analysis further revealed that the instability of nitrogen heterocyclic structures at high temperatures promotes the occurrence of ring-opening reactions, leading to the nitrogen-containing portions of PAHs predominantly existing in chain form. The formation of long carbon chains, compared to cyclic structures, facilitates the combination of carbon-hydrogen small molecules, effectively explaining the promoting effect of nitrogen-containing species on the mass growth of clusters. Overall, nitrogen-containing species exhibit significant reactivity in high-temperature environments that reduce the reaction frequency of the transformation from C₃H₃ to PAHs, effectively inhibit the cyclization of PAHs and promote the formation of branched chains. Furthermore, a looser structure with more branched chains facilitates oxidation reactions, thereby further inhibiting the growth of PAHs. This study offers important insights into the understanding of the mechanism by which ammonia inhibits the growth of PAHs in ammonia-doped hydrocarbon flames.</div></div>","PeriodicalId":17287,"journal":{"name":"Journal of The Energy Institute","volume":"120 ","pages":"Article 102020"},"PeriodicalIF":5.6,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
