REGENERATION METHOD FOR ZEOLITE MEMBRANE COMPLEX
To provide a regeneration method for a zeolite membrane complex, which enables low-cost regeneration by removing a component adsorbed onto a zeolite membrane after execution of gas separation.SOLUTION: In a method for regenerating a zeolite membrane complex, a gaseous mixture composed of a plurality of gas components is brought into contact with the zeolite membrane complex having a zeolite membrane formed on a porous support, and some of the gas components permeate it. The regeneration method for the zeolite membrane complex includes a step of bringing the zeolite membrane complex into contact with a gas mixture including carbon dioxide and at least one type of methane and ethane.SELECTED DRAWING: Figure 1
【課題】ガス分離実施後にゼオライト膜に吸着した成分を取り除き、低コストで再生することができるゼオライト膜複合体の再生方法を提供する。【解決手段】多孔質支持体上に形成されたゼオライト膜を有するゼオライト膜複合体に、複数の気体成分からなる気体混合物を接触させ、一部の気体成分を透過させたゼオライト膜複合体を再生する方法であって、メタン及びエタンの少なくとも１種と二酸化炭素とを含む混合ガスとゼオライト膜複合体とを接触させる工程を有するゼオライト膜複合体の再生方法。【選択図】図１
