研究了一种新型多孔双极滴流床电化学反应器用于碱性过氧化物的电合成。该方法使用相对简单的电池配置，其中单一电解质与氧气一起在流过式石墨毡阴极中流动，该阴极夹在微孔隔膜和穿孔双极电极板之间。石墨毡阴极为120 mm高× 25 mm宽，厚度为3.2 mm。反应器在1-5 kA m-2，ca的电流密度下运行。800 kPa（绝对压力）压力和温度（输入/输出）20-45 °C，单电池和双电池。该反应器表现出良好的性能（在2 kA m-2下电流效率为78%，并且产生的每kg过氧化物的比能量为5 kWh），过氧化物浓度为0.02至0.15 M（在1 M NaOH中）。
A novel perforated bipole trickle-bed electrochemical reactor is investigated for the electro-synthesis of alkaline peroxide. The process uses a relatively simple cell configuration in which a single electrolyte flows with oxygen gas in a flow-by graphite felt cathode, sandwiched between a micro-porous diaphragm and a perforated bipolar electrode plate. The graphite felt cathodes are 120 mm high by 25 mm wide and have a thickness of 3.2 mm. The reactor is operated at current densities in the range 1–5 kA m−2, ca. 800 kPa (abs) pressure and temperature (In/Out) 20–45 °C with one and two-cells. The reactor shows good performance (current efficiency ∼78% at 2 kA m−2 and a specific energy of 5 kWh per kg of peroxide generated) with peroxide concentrations from 0.02 to 0.15 M in 1 M NaOH.
