Abstract

Singlet oxygen (O₂(a¹Δg)), the first electronically excited singlet state of molecular oxygen, exhibits high reactivity due to its unique electron spin configuration. Its ability to introduce high-energy electron states into fuel combustion reactions makes it a promising technology in combustion science. In this paper, the research progress of O₂(a¹Δg) combustion assisted technology is comprehensively reviewed. Firstly, the basic physicochemical properties of O₂(a¹Δg) and the respective advantages and disadvantages of various excitation device production and detection methods are introduced. Then, the impact of how O₂(a¹Δg) affects the optimisation of various parameters of ignition and combustion assistance during the combustion process is highlighted. The kinetic mechanisms and molecular simulation studies of the involvement of O₂(a¹Δg) in chain reactions and chain initiation are investigated. Finally, gaps in O₂(a¹Δg) fuelled combustion are presented to provide ideas for the direction of future efforts in research. Although the concentration and stability of O₂(a¹Δg) are potentially risky, it can be effectively controlled by improving the coupling of novel combustion devices adapted to O₂(a¹Δg) with new technologies and researching new chemical catalysts. Therefore, O₂(a¹Δg)-assisted combustion is a key technology for solving combustion problems in the future. Using O₂(a¹Δg) as a novel oxidant for combustion, further catalytic combustion assisting and new reaction pathways are formed to solve the problems of ignition, steady combustion and burnout of fuels, with a view to wider technological applications, maturation and expansion of O₂(a¹Δg) in the future in the field of promoting the combustion science of different fuels.

O2（a1Δg）非热等离子体的生成技术、燃烧调制及反应机理综述

单线态氧（O2(a1Δg)）是分子氧的第一个电子激发单线态，由于其独特的电子自旋构型而表现出较高的反应活性。它能够将高能电子态引入燃料燃烧反应中，这使它成为燃烧科学中一个很有前途的技术。本文对O2（a1Δg）助燃技术的研究进展进行了综述。首先介绍了O2（a1Δg）的基本物理化学性质，以及各种激发装置生产和检测方法的优缺点。然后，重点介绍了O2（a1Δg）如何影响燃烧过程中各种点火和助燃参数的优化。研究了O2（a1Δg）参与链式反应和链引发反应的动力学机制和分子模拟研究。最后，介绍了O2（a1Δg）燃料燃烧的间隙，为今后的研究方向提供了思路。虽然O2（a1Δg）的浓度和稳定性存在潜在风险，但通过改进与O2（a1Δg）相适应的新型燃烧装置与新技术的耦合，以及研究新的化学催化剂，可以有效控制O2的浓度和稳定性。因此，O2（a1Δg）辅助燃烧是未来解决燃烧问题的关键技术。利用O2（a1Δg）作为一种新型的燃烧氧化剂，进一步形成催化助燃和新的反应途径，解决燃料的点火、稳定燃烧和燃尽问题，以期O2（a1Δg）在未来更广泛的技术应用、成熟和扩展，促进不同燃料的燃烧科学。
