主　　题：Zeolites C2 hydrocarbons Ethylene Adsorptive separation 

摘      要：Adsorptive separation of light hydrocarbons by porous solids provides an energy-efficient alternative to state-of-the-art cryogenic ***,an optimal balance between the cost,performance and stability of the sorbent material is yet to be achieved for industrial ***,we report the efficient separation of C2 and C3 hydrocarbons by a faujasite zeolite(Na-X,Si/Al=1.23).A tandem configuration of two fixed-beds packed with Na-X affords complete dynamic separation of the ternary mixture of C_(2)H_(2)/C_(2)H_(4)/C_(2)H_(6)(1/49.5/49.5;v/v/v)under ambient ***-swing desorption on the latter fixed-bed gives ethylene(99.50%,1.80 mmol g^(-1))and ethane(99.99%,1.41 mmol g^(-1)).In situ synchrotron X-ray powder diffraction revealed the binding sites for C_(2)H_(2)and C_(2)H_(4)in *** study highlights the potential application of commercial zeolites for challenging industrial separations.
