PROBLEM TO BE SOLVED: To provide a zeolite membrane composite for gas separation having excellent characteristics in the separation of a gaseous mixture.SOLUTION: In a gas separation method where a gaseous mixture consisting of a plurality of gas components is brought into contact with a zeolite membrane composite and a highly permeable gas component is permeated from the gaseous mixture, the separation is performed after pretreatment for drying the zeolite membrane composite is performed. The zeolite membrane composite having excellent characteristics in chemical resistance, heat-resistant stability and the like, excellent characteristics in the separation of a gaseous mixture and having a large permeation amount of a gas and a high separation factor is provided.SELECTED DRAWING: None |
