Abstract

Soot has harmful effects on the environment and human health. The formation process of soot includes six steps: fuel pyrolysis, soot nucleation, coalescence, surface growth, aggregation, and soot oxidation. However, the formation of soot is very complex and is influenced by factors such as fuel type, combustion conditions, and environmental temperature. Oxygenated fuels additives have a positive effect on reducing soot emissions, but recent studies have shown that oxygenated fuels can lead to an increase in the number of small particles of soot. In this paper, the effect of oxygenated fuel additives such as alcohol, ether, and esters on soot emissions is discussed in terms of the mechanism of soot formation. Subsequently, the role of after-treatment systems in reducing soot emissions is summarized. This work can update our understanding of the impact of oxygenated fuels on soot emissions.

含氧生物燃料添加剂对实验室规模烟尘排放的影响概述

烟尘对环境和人类健康有害。烟尘的形成过程包括六个步骤：燃料热解、烟尘成核、凝聚、表面生长、聚集和烟尘氧化。然而，烟尘的形成非常复杂，受燃料类型、燃烧条件和环境温度等因素的影响。含氧燃料添加剂对减少烟尘排放有积极作用，但最近的研究表明，含氧燃料会导致烟尘小颗粒数量增加。本文从烟尘形成的机理出发，讨论了含氧燃料添加剂（如醇、醚和酯）对烟尘排放的影响。随后，总结了后处理系统在减少烟尘排放方面的作用。这项工作可以更新我们对含氧燃料对烟尘排放影响的认识。

期刊介绍： Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
