采用常压等离子体和氢气分离膜，开发了一种新型的等离子体膜反应器（PMR）。还考察了由NH3生成高纯氢气的情况。首先，氢气流入PMR揭示了PMR对氢分离的影响。氢的分离取决于供给的氢气（Pin，H2）和渗透的氢气（Pout，H2）的分压，当Pin，H20.5−Pout，H20.5> 0时。第二，NH3气体流入PMR揭示其制氢特性：一个典型的等离子体反应器（PR）的最大氢气转化率为13%，而PMR转化率为24.4%。通过氢气分离获得的氢气的纯度约为100%。稳定地获得20 mL/min的氢气产生速率。
A new plasma membrane reactor (PMR) was developed to efficiently produce hydrogen from NH3with the use of atmospheric pressure plasma and a hydrogen separation membrane. The generation of high-purity hydrogen from NH3was also examined. First, hydrogen gas flowing into the PMR revealed the effect of the PMR on hydrogen separation. Hydrogen separation depends on the partial pressure of hydrogen gas supplied (Pin, H2) and permeated (Pout, H2) whenPin, H20.5−Pout, H20.5> 0. Second, NH3gas flowing into the PMR revealed its hydrogen production characteristics: the maximum hydrogen conversion rate of a typical plasma reactor (PR) is 13%, whereas the PMR converted 24.4%. Hydrogen obtained by hydrogen separation was approximately 100% pure. A hydrogen generation rate of 20 mL/min was stably obtained.
