| 摘要: |
| 天然气是一种清洁的能源，其燃烧时所产生的CO2排放量低于其他化石能源。原料天然气中含有一定量的酸性气体如CO2和H2S，在进入输气管网之前须予以脱除。膜分离工艺操作简单，在天然气脱硫、脱碳领域具有良好的应用前景。调研了近40年以来聚合物膜的发展、分离机理以及膜分离技术在天然气脱硫、脱碳领域的应用。对聚合物膜中的橡胶态聚合物膜、玻璃态聚合物膜和杂化膜的种类和应用状况进行了总结，并对膜分离技术在天然气脱硫、脱碳领域的应用进行了展望。橡胶态聚合物膜对H2S具有较高的渗透性，但H2S/CH4选择性相对较低；玻璃态聚合物膜对H2S的渗透性较低，但H2S/CH4选择性较高；杂化膜通过聚合物和功能性纳米材料、离子液体或深共熔溶剂结合，可兼顾渗透性和选择性，是未来膜分离材料的发展趋势。 |

| Abstract: |
| Natural gas is a clean energy source, and its CO2 emissions when burned are lower than those of other fossil fuels. Raw natural gas contains a certain amount of acidic gases such as CO2 and H2S, which must to be removed before entering the gas pipeline network. Membrane separation is a technology with a simple process and operation, which has a good application prospect in the field of natural gas desulfurization and decarbonization. The development of polymer membranes in the past 40 years, the separation mechanism and the application of membrane separation technology in the field of natural gas desulfurization and decarbonization were investigated. The types and applications of rubbery polymer membrane, glassy polymer membrane and hybrid membrane were summarized, and the application of membrane separation technology in the field of natural gas desulfurization and decarbonization was prospected. The rubbery polymer membrane has high permeability to H2S but low H2S/CH4 selectivity. The glass polymer membrane has low permeability to H2S but high H2S/CH4 selectivity. The hybrid membrane can balance permeability and selectivity by combining with functional nanomaterials, ionic liquids or deep eutectic solvent, which is the development trend of membrane separation materials in the future. |
