Abstract

In order to benefit from a realistic hydrogen production device equipped on a vehicle, issues with the effects of the process parameters on H 2 and CO yield need to be resolved. In this study, a reduced mechanism for n -heptane (as a surrogate diesel) reforming over a Pt/CeO 2 -Al 2 O 3 catalyst is adopted to investigate the effects of the process parameters on H 2 and CO yield, and the preferred process parameters are concluded. In addition, the comparison of reforming bench tests of diesel fuel and n -heptane under typical diesel engine operating conditions is conducted. The n -heptane reforming simulation results show that the maximum H 2 and CO yield moves toward unity with the decreased GHSV and increased reaction temperature, and the GHSV of 10,000 1/h, O 2 /C ratio of 0.6 and reaction temperature of 500 °C is preferable. The contrast experiments reveal that the change trend of H 2 and CO yield displays consistence, although the difference of the average H 2 and CO yield results is obvious. The characteristics of n -heptane reforming can represent H 2 and CO yield features of diesel fuel reforming at typical reaction temperatures in a way.
