Abstract: | This study investigates the decomposition of a gas mixture of four n-alkanes (n-heptane,
n-octane, n-nonane, and n-decane) using a dielectric barrier discharge reactor. We show that the
conversion of n-alkanes increased from 7.2% (C7H16), 9.7% (C8H18), 8.4% (C9H20), and 10.5%
(C10H22) to 23.8% (C7H16), 25.0% (C8H18), 27.9% (C9H20), and 32.1% (C10H22) when the
energy density increased from 84 J l?1 to 324 J l?1. The conversion of n-alkanes when using the
gas mixture is close to that found when using a single n-alkane. The influences of reaction
temperature and O2 concentration are also investigated, and the activation energies for the
decomposition of each alkane are given. |
