研制了一种新型的带有一个多尖端旋转电极对一个同心圆筒型固定电极的甲烷放电制备碳二烃的等离子体反应器.以氢气共存条件下甲烷偶联研究对此反应器作出了评价.在此反应器中,反应物流垂直穿过两电极之间的环行等离子体反应区.在大约40V供电电压、20kHz脉冲放电等离子体条件下,在长时间连续反应后没有产生大量积炭.在同样的条件下,此多尖端旋转电极工艺比固定的尖端-平板电极工艺具有较高的甲烷转化率、碳二烃单程收率以及较高的能量效率.
A new type of plasma reactor for producing carbon dihydrocarbons using a multi-tip rotating electrode with methane on a concentric cylindrical stationary electrode was developed. The reactor was evaluated using a methane coupling study in the presence of hydrogen In this reactor, the reactant stream passes vertically through the toroidal plasma reaction zone between the two electrodes at a supply voltage of about 40 V, 20 kHz pulsed discharge plasma conditions, after a long period of continuous reaction does not produce a large amount of coke in Under the same conditions, this multi-tip rotary electrode process has higher methane conversion rate, one-way yield of carbon and hydrocarbon and higher energy efficiency than the fixed tip-plate electrode process.
