Disclosed herein is a process for separating a hydrocarbon feed gas mixture comprising constituents including ethylene to produce a separated ethylene product. The disclosed process employs a solid-state ethylene sorbent and temperature and/or pressure swing adsorption and membrane separation and demonstrates a methodology to reduce the net heat of reaction during the adsorption of ethylene onto an adsorbent.

Solid-state copper(I) sorbents for olefin separations

Disclosed are air-stable small-molecule adsorbents trimeric [Cu&#x2014;Br]and [Cu&#x2014;H]that undergo a reversible solid-state molecular rearrangements to [Cu&#x2014;Br.(alkene)]and [Cu&#x2014;H.(alkene)]dimers. The reversible solid-state rearrangement allows one to break adsorbent design trade-offs and achieve low heat of adsorption while retaining high selectivity and uptake.
