摘要：
Alkenes may be separated from alkanes using membranes of Group 11 metal ionomers of sulfonic acid group contaning polymers, and the useful lifetime of these membranes is increased by passing the mixture containing the alkanes and alkenes over and/or through a material which reduces H2S concentrations in the feed stream before exposing the membrane to the feed stream.
