ZEOLITE, AND PRODUCTION METHOD AND USE THEREFOR

摘要

The present invention provides a novel high-silica zeolite having a high molar ration of a tetravalent element (Y) to a trivalent element (X) in terms of oxide.;A zeolite, comprising at least a trivalent element X and a tetravalent element Y, wherein a molar ratio n=YO2/X2O3 in terms of oxide is 9.5 or more, and the zeolite comprises an RHO-type structure, or comprising at least a trivalent element X and a tetravalent element Y, wherein a molar ratio n=YO2/X2O3 in terms of oxide is 9.5 or more, and a characteristic X-ray diffraction pattern.;This zeolite is produced by hydrothermal synthesis of a zeolite from an aqueous gel that is prepared by adding a mixed solution comprising a crown ether, an alkali, and water to a solution containing an aluminum atom material, and by then dropwise adding a liquid containing a silicon atom material.
