摘　　要：在脉冲电晕放电条件下,用等离子体化学反应方法研究了原位 H_2O_2的合成,考察了一些主要的参数对 H_O_2产量的影响。在室温和常压下,氢气和氧气能够在脉冲电晕等离子体条件下原位转化为过氧化氢;就过氧化氢的产量而言,针-板式反应器要优于线板式反应器;适当调整反应物(氢气和氧气)的比率、反应的空速、放电的脉冲电压和重复频率能够提高过氧化氢的产率。The in situ synthesis of H_2O_2 has been studied by using plasma chemical reaction under pulsed corona dis- charge,and the effects of some main parameters on H_2O_2 yield were also studied.Under the room temperature and atmospheric pressure,hydrogen and oxygen can be in situ converted into hydrogen peroxide in pulse corona plasma;as far as the yield of hy- drogen peroxide is concerned,the needle-plate reactor works better than the line-plate one;the proper adjustment of the ratio of reactants,the space velocity of reaction,the pulse voltage and repeated frequency of the plasma discharge can raise the yield of hydrogen peroxide.
