In this regard, the thermo-chemical approach is a promising technical option to realize this objective within the framework of the circular economy. Such approach involves transforming plastic waste into chemicals/fuels, which contributes to the build-up of a more sustainable and resource-efficient platform. Precise control over yield and selectivity towards target chemicals (monomers, light olefins, and benzene, toluene, ethylbenzene, and xylene isomers (BTEXs)) and fuels (transportation fuels and syngas) is achievable by manipulating operating parameters for the thermo-chemical platform despite the possibly marked influence of the waste composition on product distribution. This review aims to delineate a technically viable pathway of the thermo-chemical approach with the discussion on the physico-chemical properties and compositional characteristics of plastics, technical alternatives for their recycling, and the associated environmental risks (improper disposal practices including mismanagement, landfilling, and incineration). This review helps open a new path for the development of a strategic technical approach within thermo-chemical processing to integrate different facets of plastic waste recycling. Thus, it will contribute to the realization of a closed-loop circular economy within the plastic value chain by focusing on thermo-chemical recycling of plastic waste.</div></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"108 ","pages":"Article 101219"},"PeriodicalIF":32.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, two main challenges, the difficulties of flame stabilization and potential high fuel NO_x production, still need to be tackled in its application in gas turbines. In the last decades, valuable investigations were conducted to address characteristics of NH₃/air flame stabilization in swirl combustors as well as the combustion enhancement by cofiring with active molecule like CH₄ and H₂, applying plasma assistance. These measures mainly improve the flame resistance to the flow and increase the key radicals at flame base, which may provide possible solutions to the combustion chamber design. The inherent mechanisms of fuel NO_x production are highlighted by the HNO channel with the presence of OH radical. One promising strategy to mitigate NO_x in gas-turbine like combustor is the staged combustion by staging the air or fuel, which may also fit for the practical combustion chamber. The high-pressure condition and plasma assistance were found to show positive influence on both flame stabilization and NO_x control.

Carbon-nanoparticle-based nanofuels (CNFs) have recently attracted attention for their potential to significantly enhance combustion performance and reduce emissions. CNFs offer advantages such as lower toxicity, a reduced environmental footprint, and cost-effectiveness compared to metal-based alternatives. Carbon nanoparticles exhibit potential in enhancing liquid fuel combustion characteristics, particularly when used at low particle concentrations (≤0.30 % w/w), which is likely to be optimal for improving the burning rate. This enhancement can be attributed to their superior heat absorption and transfer properties, improved atomization mechanisms, and impact on combustion kinetics. This review investigates the potential of CNFs and examines the mechanisms by which they alter combustion and evaporation characteristics. Empirical evidence indicates that the increased evaporation and burning rates of CNFs are primarily due to improved radiation capture and heat transfer. The behavior of ignition is closely related to the aggregation and distribution of nanoparticles within CNF droplets, which affects fuel evaporation dynamics. Additionally, increased micro-explosion intensity and generally reduced micro-explosion frequency are observed during CNF droplet combustion. Factors such as particle size, concentration, morphology, and thermo-physical properties play crucial roles in influencing changes in evaporation rate, burning rate, ignition delay, burning period, and micro-explosion characteristics. Studies conducted at droplet, spray, and engine scales consistently support the positive effects of CNFs observed at the droplet scale. These improvements lead to enhanced combustion parameters, better engine performance and a significant reduction in harmful emissions. However, concerns remain about the potential presence of nanoparticles in exhaust emissions and their implications for the environment and human health. This review offers a comprehensive analysis of CNFs, providing insights into their potential applications and identifying areas that require further research.</div></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"106 ","pages":"Article 101198"},"PeriodicalIF":32.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142327337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
