Plasma-assisted ammonia synthesis in a packed dielectric barrier discharge (DBD) reactor at atmospheric pressure is presented in this work. A broad range of materials (commonly used as catalyst supports) with various chemical properties (acidic α -Al 2 O 3 , anatase TiO 2 and basic MgO, CaO), surface area and porosity ( α -Al 2 O 3 and γ -Al 2 O 3 ), dielectric properties (quartz wool, TiO 2 , and BaTiO 3 ), have been investigated for synergetic effects by packing them in the discharge zone of the DBD reactor. All the materials showed a substantial effect on ammonia production, which can be explained solely as a result of the effect of packing on plasma formation and not by a synergy between plasma and surface catalysis. Size and shape of packing material are found to be the key parameters in enhancing the performance. Quartz wool, closely followed by γ -Al 2 O ...

解析等离子体和催化剂载体在填充介电势垒放电反应器中合成氨的协同作用

这项工作介绍了在大气压下的填充介电势垒放电（DBD）反应器中的等离子体辅助氨合成。具有各种化学性质（酸性α-Al 2 O 3，锐钛矿型TiO 2和碱性MgO，CaO），表面积和孔隙率（α-Al 2 O 3和γ-Al）的各种材料（通常用作催化剂载体） 2 O 3），介电性能（石英绒，TiO 2和BaTiO 3）已通过将它们装在DBD反应器的排放区中进行了协同作用研究。所有材料均显示出对氨生产的实质性影响，这只能由填料对等离子体形成的影响来解释，而不是由等离子体与表面催化之间的协同作用来解释。发现包装材料的尺寸和形状是提高性能的关键参数。石英羊毛
