催化重整反应在乳化油着火过程中的研究

1引言掺水燃烧技术有着广泛的应用前景1],少量水的加入可以同时降低NOx与碳烟颗粒的生成,而不影响其燃烧效率,但也有掺水后着火时间变长的问题。燃烧过程是决定燃烧效率与排放物生成的关键过程,催化重整反应能够有效地缩短掺水燃料的着火时间。同时催化反应能够产生少量的氢气

Ignition process study of emulsified fuel's catalytic reforming reaction

The ignition process of emulsified fuel's catalytic reforming reaction in constant volume chamber was studied and the ignition curves of diesel oil,emulsified fuel(containing 20wt% water) with or without catalyst were compared.From the results of experiment and calculation,it is shown that the emulsified diesel fuel's ignition delay is longer than that of pure diesel oil,but if there was catalytic reforming reaction,the ignition delay would be shortened.Through the experiment,it is also verified that the ignition of fuel firstly occurs on the surface covered catalyst,and then spreads out the space to make the ignition easy.It is showed that catalytic reforming reaction takes an active part in the ignition of emulsified fuel.
