摘要
许多化石燃料的替代品可以减少污染物排放,然而,由于其有限的可用性、有限的能源密度、高昂的成本等因素的综合作用,许多燃料在与化石燃料竞争时面临着巨大的困难。甲醇(CH_(3)OH)是这些替代品之一,它以纯品形式或混合成分,用于内燃机(ICEs)或直接甲醇燃料电池(DMFCs)。介绍了甲醇的历史发展及生产方法,总结了甲醇作为燃料的健康和安全特性;然后对目前有关ICEs的物理和化学性质的数据进行了回顾,突出了甲醇与乙醇和汽油等燃料的区别;从功率输出、峰载效率和部分负载效率以及排放等方面对弹性燃料发动机和专用发动机的甲醇性能进行了总结。还阐述了发动机硬件的变化和材料的兼容性,讨论了利用发动机余热对甲醇燃料进行重整,作为进一步提高效率和减少排放的一个潜在途径。最后展望了未来甲醇的研究领域。
Many alternatives to fossil fuels can reduce pollutant emissions.However,due to limited availability,limited energy density,high cost or the combination of these factors,many fuels face great difficulties in competing with fossil fuels.Methanol(CH_(3)OH)is one of these alternatives.It can be used in pure form or mixed components for internal combustion engines(ICES)or direct methanol fuel cells(DMFCs).Herein,we introduces the historical development of methanol and its production methods,and summarizes the health and safety characteristics of methanol as fuel;The current data on the physical and chemical properties of ices are reviewed,highlighting the differences between methanol and fuels such as ethanol and gasoline;The methanol performance of elastic fuel engine and special engine is summarized from the aspects of power output,peak load efficiency,partial load efficiency and emission.This paper also briefly discusses the changes of engine hardware and material compatibility,and discusses the use of engine waste heat to reformate methanol fuel as a potential way to further improve efficiency and reduce emissions.Finally,this paper also points out the areas of future research.
