experimental device Recently, the high-performance metal palladium composite membrane material of the Methane Highly Efficient Conversion New Material and New Process Research Group (DNL1902 Group) of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences has been successfully demonstrated in the purification of ultrapure hydrogen gas. The demonstration scale is 30 m3/h. hydrogen. The team used hydrogen with a purity of 99.99956% as the raw material, containing 3.81 ppm of nitrogen as impurity and 0.60 ppm of carbon dioxide as impurity. Under the condition of maintaining the hydrogen recovery rate of 91.8%, the hydrogen purity of the product reached 99.9999996%, of which the nitrogen content was 4.3 ppb. Carbon dioxide. During the stability investigation, no impurity nitrogen and carbon dioxide were detected in the product hydrogen after 24 hours. The technical demonstration was conducted continuously for 125 hours, and no impurity nitrogen and carbon dioxide were detected at all times. Ultrapure hydrogen is widely used in strategic emerging industries such as electronic information, semiconductors, LED, and polysilicon photovoltaic power generation. This technology demonstration is the main research task of the national “863†membrane special subject “Ultra-pure Hydrogen Separation Membrane Material and Scaled Preparation Technologyâ€. The demonstration was supported by the full range of support provided by Zhejiang Haitian Body Co., Ltd. in terms of equipment support, technology, engineering, and manpower.
