Abstract
There is provided a zeolite separation membrane-provided article having gaps or pores larger than pores inherent to zeolite crystals and controlled within an appropriate range and being capable of achieving both high permeability and high separability for components with small difference in adsorption properties or a component having a smaller molecular diameter than the diameter of the pores, a method for producing the same, a method for separating mixed fluids, and a device for separating mixed fluids. The zeolite separation membrane-provided article is provided with a zeolite membrane having an Ngas permeation speed at room temperature of 1.0×10mol·m·s·Paor more and a permeation speed ratio of 1,3,5-trimethylbenzene/Nat room temperature of 0.17 or more and being free from dyeing caused by the impregnation with Rhodamine B.
