摘　　要：基于介质阻挡放电(DBD)催化燃料蒸汽重整试验平台,系统地研究了水蒸气与甲烷物质的量比n(H2O)/n(CH4)、壁面温度、停留时间、输入功率及频率等对甲烷蒸汽重整过程中的有效碳回收率、甲烷转化率及其产物选择性等的影响.结果表明:当停留时间为0.29s时,有效碳回收率为96%,随着停留时间的增加,有效碳回收率线性下降;增加停留时间及增大n(H2O)/n(CH4)和输入功率有利于甲烷转化;停留时间为0.59s时,不同操作条件下甲烷转化率在20%以上,H2选择性在20%左右,C2+C3选择性在20%左右,CO选择性在4%左右,有C4以上高碳烃生成.A series of experiments were conducted based on dielectric barrier discharge （DBD） catalytic fuel reforming test platform, so as to study the effects of following factors on the effective carbon recovery rate, methane conversion rate and product selectivity, such as the ratio of n（HzO）/n（CH4 ）, wall tempera- lure, residence time, input power and frequency, etc. Results show that the effective carbon recovery rate may reach 96O/oo when the residence time is 0.29 s, which reduces linearly with rising residence time; the methane conversion rate can be promoted by increasing the residence time, the n（H2O）/n（CH4） or the input power; for a residence time of 0.59 s, the methane conversion rate is more than 200/00 under different operation conditions, and the selectivity of Hz, C2 ＋C：3 and CO is respectively 20%, 20% and 4%, with C4 ＋ heavy hydrocarbons generated.
