摘要
氢气在钯膜中的传递服从"溶解-扩散"机理。钯膜可以单独组成膜分离器,用于生产高纯度的氢气,也可以与氢气的生产过程相耦合,形成钯膜反应器,用于通过再线的氢气分离打破制氢过程的化学反应平衡,一步法生产高纯氢气。主要介绍了当前膜分离器和反应器的研发进展,介绍了几种膜分离器及反应器的概念设计,并指出了钯膜技术的发展方向。
The hydrogen transmitting through Pd membrane follow the" dissolution-diffusion" mechanism. Pd membrane can be used in the production of high purity hydrogen by developing membrane separators. It can also form membrane reactors coupled with hydrogen production process, break the hydrogen chemical equilibrium through the in-situ hydrogen separation, and produce high purity hydrogen in one-step. The research progress of membrane separators and reactors was reviewed, and needs for further develop- ment were pointed out.
