In the present work, the effect of plasma power and oxygen flow rate on methane conversion and methanol selectivity in a DBD reactor. The results indicate that increasing power at constant gas flow rate leads to enhancing methane conversion relatively linearly, while methanol selectivity is improved initially and then declines. Moreover, increasing oxygen flow rate from 40 sccm to 75 sccm at a constant methane flow rate of 100 sccm leads to rise in methane conversion and methanol selectivity. The results show that formation of copper oxide on electrode surface can be very effective in achieving high methanol yields.

NTP等离子体将甲烷选择性氧化为甲醇:功率和氧气对转化率和选择性的影响

在当前的工作中,等离子体功率和氧气流速对DBD反应器中甲烷转化率和甲醇选择性的影响。结果表明,在恒定气体流速下增加功率会相对线性地提高甲烷转化率,而甲醇的选择性先得到提高,然后下降。此外,在恒定的甲烷流速为100 sccm的情况下,将氧气流速从40 sccm增加到75 sccm会导致甲烷转化率和甲醇选择性的提高。结果表明,在电极表面形成氧化铜可以非常有效地实现高甲醇收率。
