In this study, the oil recovery performance of DES, synthesized from tetrabutylammonium bromide (TBAB) and polyethylene glycol 400 (PEG 400) in a 1:2 molar ratio, and the switchable solvent N,N-dimethylcyclohexylamine (DMCHA) was evaluated through a displacement test. Additionally, the interactions between the rock, solvents, and crude oil were investigated through interfacial tension (IFT) measurements using an Altension tensiometer. The trend in the experimental IFT results was compared to the interactions between DMCHA and oil, DMCHA and rock, DES and oil, and DES and rock using quantum mechanics calculations performed with the Spartan v20 molecular modeling tool. The findings revealed that the IFT between the solvents and oil decreased to 5.32 mN/m with DES and 2.64 mN/m with DMCHA. Furthermore, core flooding experiments showed an incremental recovery of 12.0 % of the original oil in place (OOIP) with DES and 10.0 % OOIP with DMCHA for standard Berea sandstone core samples. Similarly, flooding experiments using Niger-Delta sandstone samples achieved an additional 25.8 % OOIP with DES compared to 12.0 % OOIP with DMCHA. In conclusion, both DES and DMCHA demonstrated their potential for crude oil recovery. However, DES proved to be more promising for tertiary enhanced oil recovery applications.</div></div>","PeriodicalId":100556,"journal":{"name":"Fuel Communications","volume":"22 ","pages":"Article 100133"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis employs OpenLCA software to compare the environmental effects of RDF against traditional fossil fuels fuel oil and coal during colder months when natural gas is scarce. The study examines two RDF compositions, including organic waste and one excluding it, to determine their impacts on sustainability and fuel efficiency. Key findings indicate that RDF, mainly when produced with organic waste, offers substantial reductions in global warming potential (GWP) and other environmental impacts compared to conventional fuels. Specifically, the results demonstrate that RDF can significantly lower CO₂ emissions associated with cement production, positioning it as a viable option for enhancing energy sustainability within the industry. This research underscores the importance of integrating waste management strategies with energy recovery solutions, providing valuable insights for policymakers aiming to address both waste disposal and energy needs sustainably.</div></div>","PeriodicalId":100556,"journal":{"name":"Fuel Communications","volume":"22 ","pages":"Article 100135"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Basic properties of boiling point, flash point, freezing point, density and viscosity are well suited for blending into diesel fuels. For the mixture of ethers the lightest component, di-n-butyl ether, can be present at up to 20 vol% while still having adequately high flashpoint for safe handling. Soot formation tendency (as yield sooting index) is well below that of conventional diesel. The ethers have similar compatibility with elastomers as conventional diesel, based on Hansen solubility parameter analysis. Oxidation stability was assessed for 30 vol% blends of individual ethers in a conventional diesel fuel using a long-term storage test. Over 6 weeks we observed no formation of peroxides or degradation. n-alkyl ethers with carbon number of 8 or higher have cetane number over 100, which is outside the defined range of cetane number, while branched ethers are over 70. The ethers also blend antagonistically into conventional diesel for cetane number, meaning that the blend cetane value is lower than predicted based on a linear by volume, mass, or mole model. We show that aromatics and naphthenes likely act as radical scavengers to slow or shut down autoignition of the highly reactive ethers at low to medium blend levels. Overall, diesel boiling range ethers show significant promise as high quality low-net carbon diesel blendstocks.</div></div>","PeriodicalId":100556,"journal":{"name":"Fuel Communications","volume":"22 ","pages":"Article 100131"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dependencies of the average specific heat capacity on composition and temperature are thus of significance in interpreting differences in the achievable combustion temperature of different fuels. In this contribution, these dependencies are discussed and evaluated to provide simple correlations for use in practice. The correlations are applicable over the wide temperature range of 25…1600°C, while deviations at higher temperature are mainly due to dissociation of polyatomic gases. The provided correlations are also applicable if an oxygen carrier other than air is used, so that they are useful for a wide range of practical applications. This study also shows that the specific heat capacities of flue gases from different fuels are very similar, which is another reason – besides their similar \"heat of oxidation\" – why the adiabatic flame temperatures of different fuels are within a narrow range.</div></div>","PeriodicalId":100556,"journal":{"name":"Fuel Communications","volume":"23 ","pages":"Article 100136"},"PeriodicalIF":0.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the non-thermal characteristics of the two heating sources that the H₂/air flat flame emits ultraviolet light, whereas infrared light as thermal radiation is emitted within the electric furnace, the possibility of NH₃ photolysis in the H₂/air flat flame case is discussed based on literature regarding emissions from the H₂/air flames, the transmittance of the quartz tube, and the photodissociation of NH₃ in the ultraviolet region. When ultraviolet light emitted from the H₂/air flat flame passes through the quartz tube and decomposes NH₃ into NH₂ and H radicals, these produced radicals enhance the growth of OH radicals, resulting in increased NH₃ reactivity. These findings suggest the possibility of photolysis-assisted ammonia combustion, which could be an additional method to overcome the low reactivity of NH₃.</p></div>","PeriodicalId":100556,"journal":{"name":"Fuel Communications","volume":"21 ","pages":"Article 100130"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666052024000256/pdfft?md5=9d520c2f438656e3cacdeeeeb7b18442&pid=1-s2.0-S2666052024000256-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142172888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
