| description | The invention provides a method for one-step separation and purification of ethylene based on a stable metal-organic framework material rich in Lewis alkaline sites, and the method adopts the stable metal-organic framework material rich in Lewis alkaline sites as an adsorbent, and the stable metal-organic framework material rich in Lewis alkaline sites is fully contacted with complex component feed gas to obtain the ethylene. Impurities such as acetylene, ethane and water vapor in raw material gas are selectively adsorbed, so that one-step purification of ethylene is realized. The stable metal-organic framework material rich in Lewis alkaline sites is a high-performance porous crystalline material formed by coordination connection of high-valence metal ions and heterocyclic dicarboxylic acid ligands containing Lewis alkaline sites. Compared with a conventional adsorbent, a stable metal-organic framework material rich in Lewis alkaline sites adopted by the separation and purification method not only solves the |
