ZEOLITE MEMBRANE COMPOSITE FOR GAS SEPARATION AND PRODUCTION METHOD OF THE SAME

摘要

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 zeolite membrane composite for gas separation having a zeolite membrane on a ceramic support, an air permeation amount is 700 L/(mh) or less. The zeolite membrane includes a zeolite of a CHA type aluminosilicate whose main component is the oxide of Si and Al. The zeolite membrane composite being excellent in chemical resistance, heat-resistant stability and the like, having a large amount of a gas permeation amount, having a high separation factor and being excellent in the separation of a gaseous mixture is provided.SELECTED DRAWING: None
