Gas separation devices |
摘要 |
A gas separation device for the removal of carbon oxides from a hydrogen-rich gas stream in the form of a composite comprising a hydrogen diffusion membrane and a methanation catalyst. The hydrogen diffusion membrane may be applied to the upstream surface of a porous or microporous support and the methanation catalyst may be applied to the downstream surface of the porous or microporous support. The gas separation device is particularly useful for negating pinhole leakages of carbon monoxide through palladium alloy membrane by virtue of the polishing-up action of the methanation catalyst |
