摘要： A process for producing a zeolite molding characterized in that the process comprises adding a tetrapropylammonium hydroxide (TPAOH) solution and tetrapropylammonium bromide (TPABr) to silica sol to thereby obtain a preparation liquid, heating the preparation liquid in a sealed vessel under such conditions that crystallization and/or precipitation would not occur in the preparation liquid, drying the preparation liquid after heating treatment, molding the thus obtained dry gel and effecting crystallization of the molded dry gel in steam. This process enables efficiently producing a zeolite molding on which a zeolite film can be formed and maintained without cracking and which when used as a gas separation film such as molecular sieve film or a pervaporation film, satisfies both requirements for decrease of pressure loss and sustenance and enhancement of mechanical strength.

摘要： A porous zeolite shaped body of a zeolite is characterized in that the porous zeolite shaped body is made of a completely crystallized zeolite or a zeolite still under crystallization and composed of tetrapropylammonium ion (TPA) and silica sol in a mixing ratio (TPA/SiO2) of 0.015 to 0.08 by mole: a zeolite shaped body has an average particle diameter of 1.0 mu m or larger, a bending strength of 1.5 MPa or higher, and a difference in pressure between a feed side and a permeation side of 1.0 atmospheric pressure or lower at 10 ml/cm . min of helium gas permeation flux when a thickness of the porous zeolite shaped body is adjusted to be 1.8 mm: and a zeolite shaped body has 70% or more of the area of the parts (the sound parts) where respective particles are clearly observed by grain boundary fracture among particles composing the shaped body in the entire area of the fractured surface in microstructure observation of the fractured surface of the shaped body itself.
