Natural gas is essential for the world's supply of energy due to its economic viability and environmental sustainability in producing adequate amounts of clean energy. However, the removal of CO₂ as an undesirable impurity remains challenging in natural gas purification. In this work, high performance dense mixed matrix membranes (MMMs) containing a low loading (<2 wt%) of zeolitic imidazolate framework 8 (ZIF-8) and polysulfone (PSF) were prepared via simple solvent evaporation method and single solvent for the removal of CO₂ from CH₄.

含有沸石咪唑酯骨架 8 和聚砜的高性能膜，用于从 CH4 中去除 CO2

由于天然气在生产足够数量的清洁能源方面具有经济可行性和环境可持续性，因此对世界能源供应至关重要。然而，去除作为不希望的杂质的CO ₂在天然气净化中仍然具有挑战性。在这项工作中，通过简单的溶剂蒸发法和单一溶剂制备了含有低负载量（<2 wt%）的沸石咪唑酯骨架 8（ZIF-8）和聚砜（PSF）的高性能致密混合基质膜（MMM）。从 CH ₄中去除 CO ₂。
