Selecting for ethylene Purification of from other gases produced during its synthesis, such as acetylene, ethane, and carbon dioxide, is an energy-intensive process. Chen et al. use a mixture microporous metal-organic framework physisorbents that are selective one these four gases. A series sorbents in packed-bed geometry pure enough making polymers.
