主 题:Natural gas Adsorption Separation Light hydrocarbons MOF
摘 要:Natural gas processing involves the separation of higher hydrocarbons(C2–C3)from methane,which is an important and energy-intensive *** this paper,we present a comprehensive study of an innovative copper-based MOF(Cu-MOF)for the separation of propane and ethane from *** material exhibits a high adsorption capacity and selectivity for C2–C3 hydrocarbons over methane,which is primarily due to its preferential C2–C3 hydrocarbon *** adsorption isotherms at ambient conditions showed a remarkable uptake of C_(3)H_(8)of 134.0 cm^(3)/g,as well as excellent selectivity of 204 and 9 for C_(3)H_(8)/CH_(4)and C_(2)H_(6)/CH_(4).According to the theoretical calculations,differences in van der Waals interactions and polarizability of the guest molecules were responsible for influencing separation *** addition,we conducted adsorption kinetic experiments,dynamic breakthrough,and cycling experiments to further examine the separation ***,this research establishes an energy-efficient adsorbent for upgrading natural gas.
