PROCESS FOR OBTAINING A HYDROCARBON-ENRICHED FRACTION FROM A GASEOUS FEEDSTOCK COMPRISING A HYDROCARBON FRACTION AND CARBON DIOXIDE

摘要

The present invention provides a process for obtaining a hydrocarbon-enriched fraction from a gaseous feedstock comprising a hydrocarbon fraction and carbon dioxide, which process comprises the steps of: providing a membrane having a retentate side and a permeate side; and contacting the feedstock with the retentate side of the membrane, obtaining a hydrocarbon-enriched fraction at the permeate side of the membrane, wherein the membrane is an organic modified mesoporous membrane.
