摘要

摘要: 为了对不同芳香烃种类及含量在航空发动机上表现开展综合评定,对16种芳香烃的3种配比调和燃料开展发动机排放尾气碳烟浓度实验。根据实测颗粒物排放浓度值,对芳香烃的种类与含量增长对排放的影响进行比较;通过线性拟合计算芳香烃特性与颗粒物PM(particulate matters)排放的相关性;结合燃料的能量密度与排放两大重要因素,给出综合评定排名。分析结果表明:茚与萘系类产生的PM数浓度显著更高,而加氢处理后对排放有明显改善。芳香烃的密度和碳氢比对PM的影响最大,并随着芳烃浓度的增加影响越显著。对异丙苯与苯乙烯在综合评定中被列为最优两种芳烃,对萘系列加氢处理可同时优化比能与排放。该结果为通过控制燃料中芳烃种类来优化燃料提供了研究基础。

Abstract: In order to carry out comprehensive evaluation of the performance of different aromatic hydrocarbon types and contents on aero engines, engine emission exhaust soot concentration experiments on 3 blended fuels of 16 aromatic hydrocarbons were conducted. According to the measured particulate emission concentration value, the effects of the types and content of aromatic hydrocarbons on the impact of emissions were compared; the correlation between aromatic hydrocarbon characteristics and PM emissions was calculated through linear fitting; and by combining these two important factors of fuel energy density and emissions, a comprehensive evaluation ranking was given. The analysis results showed that the PM concentration produced by indene and naphthalene series was significantly higher, and the emission after hydrotreatment was significantly improved. In addition, the density and carbon-hydrogen ratio of aromatic hydrocarbons had the greatest influence on PM, and the influence became more significant with the increase of aromatic hydrocarbon concentration. Finally, p-cumene and styrene were listed as the best two aromatic hydrocarbons in the comprehensive assessment. In addition, the series of naphthalene hydrotreating can simultaneously optimize specific energy and emissions. This result provides a research basis for optimizing fuels by controlling the types of aromatics in the fuel.
