SUPPORTED CARBON MOLECULAR SIEVE MEMBRANES AND METHOD TO FORM THEM

A supported carbon molecular sieve (CMS) membrane is made by contacting a film of a carbon forming polymer on a polymer textile to form a laminate. The laminate is then heated to a temperature for a time under an atmosphere sufficient to carbonize the film and polymer textile to form the supported CMS membrane. The supported CMS membrane formed is a laminate having a carbon separating layer graphitically bonded to a carbon textile, wherein the carbon separating layer is a continuous film. The supported CMS membranes are particularly useful for separating gases such as olefins from their corresponding paraffins. 负载型碳分子筛(CMS)隔膜通过使成碳聚合物的膜在聚合物织物上接触以形成层压体而制成。然后在足以使膜和聚合物织物碳化以形成负载型CMS隔膜的气氛下将层压体加热至一定温度持续一定时间。形成的负载型CMS隔膜是具有以石墨方式结合至碳织物的碳分离层的层压体，其中所述碳分离层为连续膜。负载型CMS隔膜对于从其相应的链烷烃中分离气体如烯烃特别有用。
