Abstract: A method is disclosed for the separation of ethane and heavier hydrocarbons or propane and heavier hydrocarbons from natural gas to provide a methane-rich natural gas stream and less volatile natural gas liquids (NGLs). This method provides for passing a natural gas feedstream though a regenerable adsorbent media which adsorbs the NGLs to provides the methane rich natural gas product. The regenerable adsorbent media of the present invention is a pyrolized macroporous polymer adsorbent media.

Abstract: Brominated styrene-butadiene copolymers are useful gas transport films. The gas transport films are made by brominating a starting styrene-butadiene copolymer, and then forming the brominated styrene-butadiene copolymer into a film The film may contain a blend of the brominated styrene-butadiene copolymer with one or more other polymers. The films have excellent selectivities between certain pairs of gasses, and exhibit high gas transport rates for various gasses such as carbon dioxide and water vapor.

Abstract translation: 溴化苯乙烯 - 丁二烯共聚物是有用的气体输送膜。 气体输送膜通过溴化起始苯乙烯 - 丁二烯共聚物，然后将溴化苯乙烯 - 丁二烯共聚物形成膜来制备。该膜可以含有溴化苯乙烯 - 丁二烯共聚物与一种或多种其它聚合物的共混物。 这些膜在某些气体对之间具有优异的选择性，并且对于诸如二氧化碳和水蒸气的各种气体表现出高的气体输送速率。
