PROCESS FOR PRODUCING VET-TYPE ZEOLITE

WIPO Patent Application WO/2014/112601

A1

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 M1 source, 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 M1O2/ZnO ratio of 5-30 and adding the zeolite to the reaction mixture in an amount of 0.1-30 wt% relative to the M1O2 contained in the reaction mixture, and (3) heating the reaction mixture to which the seed crystals have been added, at 80-200ºC in a hermetically closed state. M1 represents silicon or a mixture of silicon and germanium.
