摘要：柴油废气重整不仅可以利用柴油机废气的热量,而且重整产物(富氢混合气)还能有效改善柴油机的性能。论文介绍了柴油废气重整制氢的基本概念和反应机理,以正庚烷代替柴油,利用CHEMKIN软件建立了柴油废气重整反应的化学动力学模型,该模型包括37种组分和58个反应。论文模拟研究了反应温度和水碳比对柴油废气重整反应的影响。模拟分析结果表明:反应温度和反应物的水碳比(molH2O/molC)对重整反应有较大的影响。

Abstract: Exhaust gas diesel fuel
reforming can utilize the heat of exhaust gas. Moreover,the reforming
products(rich-hydrogen mixtures) can improve the performance of diesel
engine.This paper presents the basic concept and reaction mechanism of exhaust
gas diesel fuel reforming.The reaction mechanism includes 35 species and 40 reactions.The
chemical kinetics model of exhaust gas diesel fuel has been developed using the
CHEMKIN platform and n-heptane instead of diesel.A detailed simulation study is
carried to investigate the effects of reaction temperature and the H2O/C
ratio.The results show that reaction temperature and species proportion
influence the exhaust gas diesel fuel reforming reaction significantly.
