Abstract
A process for producing a VET-type zeolite is provided in which the use of a structure-directing agent is minimized and the environmental burden can be minimized. This process for producing a VET-type zeolite comprises (1) mixing a zinc source, an element Msource, an alkali source, and water so as to result in a reaction mixture having a specific composition in terms of molar ratio, (2) using, as seed crystals, a VET-type zeolite which has an MO/ZnO ratio of 5-30 and adding the zeolite to the reaction mixture in an amount of 0.1-30 wt % relative to the MOcontained in the reaction mixture, and (3) heating the reaction mixture to which the seed crystals have been added, at 80-200° C. in a hermetically closed state. Mrepresents silicon or a mixture of silicon and germanium.
