The research of new porous metal-organic frameworks (MOFs) is receiving considerable attention worldwide owing to their potential for gas adsorption, storage and separation. Separation of light hydrocarbons is a highly challenging and energy-intensive industrial process. We seek to develop highly robust MOF materials as high capacity hydrocarbon separation systems and request 9 days on TOSCA to study the binding interaction between adsorbed gas molecules (C2H2/C2H4/C2H6/C3H6/C3H8) and a robust porous MOF material (MFM-520) as a function of gas loading. This proposed study will investigate the vibrational properties exhibited by both adsorbed gas substrates and the porous hosts. MFM-520 exhibits exceptionally high separation capacity for (C2H2/C2H4/C2H6 and C3H6/C3H8) at ambient conditions with fully repeatable cycles, suggesting the presence of specific guest-host interaction.
