摘要:
A process for separating a gas from a gas mixture containing an organic compound gas or vapor by a hybrid separation combining adsorption with membrane gas separation, using membranes selective for the gas over the organic compound. The membranes use a selective layer made from a polymer having repeating units of a fluorinated cyclic structure of an at least 5-member ring, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment.
