Abstract
There are provided methods for producing a zeolite layered composite, methods for producing a zeolite shaped body and methods for producing a zeolite layered intermediate body. In one aspect, there is provided a method for producing a zeolite layered composite, comprising layering a template-containing zeolite membrane having a composition the same as or similar to that of a zeolite shaped body of a completely crystallized zeolite composed of tetrapropylammonium ion (TPA) and silica sol in a mixing ratio (TPA/SiO) of 0.015 to 0.08 by mole and containing a template therein on the zeolite shaped body, and simultaneously removing the template from the zeolite membrane and the zeolite shaped body by calcining the resulting layered product to obtain a zeolite layered composite comprising the zeolite shaped body and the zeolite membrane layered thereon.
