In this study, we first extracted shale kerogen samples from the undeformed and tectonically deformed shale (TDS) and then investigated how shale kerogen molecular structures respond to structural deformation by combining Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The result showed that structural deformation reduced the complexity and branching degree of molecular structures by promoting the breaking of aliphatic side chains and increased the aromaticity and structural order of kerogen molecules by enhancing condensation of aromatic rings. Additionally, shale kerogen displayed a relative enrichment of carbon by removing oxygen-, nitrogen-, and sulfur-containing functional groups. The removal of oxygen-containing functional groups was the most significant, showing a trend of “C-O bonds within aliphatic functional groups &gt; C-O bonds within aromatic functional groups &gt; C=O bonds within functional groups”. In general, the evolution of kerogen molecular structures caused by brittle and ductile deformation followed largely consistent patterns. However, the influence of ductile deformation was much more significant and pronounced than that of brittle deformation, and weak brittle deformation had little impact on kerogen molecular structures.</div></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"280 ","pages":"Article 108374"},"PeriodicalIF":7.7,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145681081","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}

This work demonstrates that a hierarchical MFI-type zeolite (HMFI@Z), when used in a regenerative fixed-bed column, efficiently removes cyclohexane carboxylic acid (ACHC) from petroleum-produced water under realistic conditions. Operational optimization revealed that higher feed concentrations and flow rates accelerated breakthrough and column exhaustion, with a maximum uptake of 3.44 mg g⁻¹ under 35 mg L⁻¹ and 10 mL min⁻¹. Validation with real effluent yielded a removal efficiency of 58.15 %, breakthrough at 10 min, and complete saturation at 80 min. Dynamic models showed excellent agreement with experimental data, supporting the scalability of the process. The adsorbent maintained over 80 % adsorption capacity across 17 recycles, underscoring its long-term reusability. High performance was attributed to the material's surface acidity, hierarchical porosity, and stable electronic features. Quantum chemical calculations revealed that deprotonated HMFI@Z surfaces — particularly O⁻ sites — act as the most reactive centers for ACHC binding. Key electronic descriptors corroborated the experimentally observed interactions and regeneration behavior. Two main interaction pathways were identified: (i) hydrogen bonding and electrostatic interactions dominating initial adsorption, and (ii) electron donor–acceptor mechanisms contributing to retention and stability.

A numerical model is developed to characterize the gasifier-engine system. Detailed thermodynamic sub-models for the biomass gasification reactor and for the internal combustion engine are implemented. After validation, a comprehensive analysis of the CHP (Combined Heat and Power) performance parameters is carried out under various operating conditions. The optimal configurations are identified in terms of gasifier equivalent ratio, optimal engine spark ignition advance, overall energy performance, and Primary Energy Saving index. The techno-economic analysis includes three scenarios: the baseline, in which the costs are actualized on 2019, and additional two cases with +25 % and + 50 % of energy cost increases to account for the current world geopolitical situation and analyze the sensitivity of the obtained results to cost variation. Furthermore, two functioning strategies are considered: the ON strategy, in which the system operates continuously at nominal conditions, and the ON-OFF one, in which the system is switched off during low-demand periods. The former is found to be less economically convenient, whereas the latter is proven to be economically viable. The selected optimal configuration achieved a 22.33 % Primary Energy Saving index. Furthermore, the electric and thermal efficiency are 23 % and 63 %, respectively, reaching 86 % total efficiency. Finally, the discounted payback period ranges from 4.7 to 5.9 years across the three scenarios, maintaining economic viability despite rising energy costs.

Gasification tests demonstrated strong composition dependence, with different activity trends in the Ce-rich and Fe-rich regimes.
