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% (C 7 H 16 ), 9.7% (C 8 H 18 ), 8.4% (C 9 H 20 ), and 10.5% (C 10 H 22 ) to 23.8% (C 7 H 16 ), 25.0% (C 8 H 18 ), 27.9% (C 9 H 20 ), and 32.1% (C 10 H 22 ) 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 O 2 concentration are also investigated, and the activation energies for the decomposition of each alkane are given.

使用DBD反应器分解四种正构烷烃的气体混合物

这项研究使用介电势垒放电反应器研究了四种正构烷烃（正庚烷，正辛烷，正壬烷和正癸烷）混合气体的分解。我们显示正构烷烃的转化率从7.2％（C 7 H 16），9.7％（C 8 H 18），8.4％（C 9 H 20）和10.5％（C 10 H 22）增加到23.8％当能量密度从84 J l -1增加到324 J l-时，（C 7 H 16），25.0％（C 8 H 18），27.9％（C 9 H 20）和32.1％（C 10 H 22） 1。使用混合气体时，正构烷烃的转化率接近使用单一正构烷烃时的转化率。还研究了反应温度和O 2浓度的影响，并给出了每种烷烃分解的活化能。
