Abstract
Separation of propane and propylene is an important issue in the chemical industry due to their similar properties. In this study, the proof-of-concept of propane-propylene separation using urea clathrates was demonstrated from a thermodynamic viewpoint. We found that the thermodynamic stability of urea clathrate including propane (hereafter, propane/urea clathrate, which means “guest(s)/host clathrate”) is significantly different from that of propylene/urea clathrate, which provides us with the possibility of propane-propylene separation by urea clathrate formation. When the urea clathrates were prepared from the mixtures of propane and propylene, propane was concentrated in the (propane + propylene)/urea clathrates, whereas propylene was concentrated in guest fluid phase under the coexistence with urea clathrates. The separation of propane by urea clathrate formation would be better suited for the preseparation before other separation techniques.
