Abstract:研究了介质阻挡放电等离子体对分子氧和丙烯直接合成环氧丙烷(PO)的活化作用.丙烯、氧等离子体是在室温和大气压下、在筒(线)-筒式反应器中通过介质阻挡放电产生的.实验中主要考察了介质阻挡放电电压、不同正放电电极及反应气总流量对丙烯转化率、PO选择性的影响.)反应物及各产物通过在线色谱法进行分析.实验数据表明:在室温和大气压下,用介质阻挡放电法可转化丙烯和氧气直接生成PO.采用不锈钢正电极(φ3),在总反应气流量为160.8 ml/min,介质阻挡放电电压为21 kV,介质阻挡放电频率为1.38 kHz,O2/C3H6=200/1的条件下,丙烯转化率及PO的选择性分别为81.59%和30.61%.
