In this work, ammonia (NH 3 ) synthesis from N 2 and H 2 was carried out in a packed-bed dielectric barrier discharge (DBD) reactor, while three kinds of commercial packing materials including acidic γ -Al 2 O 3 , alkaline γ -Al 2 O 3 and neutral alumina pellets were employed. The effect of packing materials on plasma-assisted NH 3 synthesis was investigated and compared with an unpacked DBD reactor. The results show that the presence of packing materials enhanced the plasma-assisted NH 3 synthesis by 15.6% to 44.4% compared to the plasma reaction without a packing. The highest NH 3 concentration of 1565.5 ppm was obtained over the alkaline γ -Al 2 O 3 packed plasma reactor. The improvement of packing materials on plasma-assisted NH 3 synthesis followed the order of alkaline γ -Al 2 O 3 > neutral γ -Al<...

填充床介质阻挡放电反应器中γ-Al 2 O 3颗粒上的氨合成

在这项工作中，由N 2和H 2在填充床介质阻挡放电（DBD）反应器中合成氨（NH 3），同时使用了酸性γ-Al 2 O 3，碱性γ三种商业填充材料。使用-Al 2 O 3和中性氧化铝颗粒。研究了填充材料对等离子体辅助NH 3合成的影响，并将其与未包装的DBD反应器进行了比较。结果表明，与没有填充的等离子体反应相比，填充材料的存在使等离子体辅助的NH 3合成提高了15.6％至44.4％。在碱性γ-Al2 O 3填充等离子体反应器中获得最高的NH 3浓度1565.5 ppm。等离子体辅助NH 3合成中填充材料的改进遵循碱性γ-Al 2 O 3>中性γ-Al <...的顺序。
