Composite membrane for hydrogen separation as well as preparation method and application thereof
The invention provides a composite membrane for hydrogen separation as well as a preparation method and application thereof. The composite membrane comprises a support body, wherein vanadium carbide membranes are respectively arranged on two sides of the support body; the support body can be compact metal, compact metal alloy, porous metal or porous ceramic, and the molar ratio of vanadium to carbon in the vanadium carbide membrane can be (1-4): 1. The composite membrane disclosed by the invention has excellent hydrogen catalytic dissociation performance, shows good stability in a high-temperature environment, has the advantages of good hydrogen permeability, high hydrogen production efficiency, wide operation temperature range, low cost and the like, and has a wide application prospect inthe field of high-purity hydrogen production.
本发明提供了一种用于氢气分离的复合膜及其制备方法和应用。本发明的复合膜包括支撑体，在所述支撑体的两侧分别设有碳化钒薄膜；其中，支撑体可以为致密金属、致密金属合金、多孔金属或多孔陶瓷，碳化钒薄膜中钒与碳的摩尔比可以为(1‑4)：1。本发明的复合膜具有优异的氢催化解离性能，在高温环境中表现出良好的稳定性，具有氢渗透性好、产氢效率高、操作温度范围宽、成本低等优势，在高纯氢生产领域具有广阔的应用前景。
