Beschreibung
Zusammenfassung:	One aspect of the present invention relates to a method for manufacturing a zeolite catalyst with a silica coating, the method includes at least: mixing a zinc source and an MFI-type zeolite to obtain a zinc-doped zeolite; preparing a mixture liquid containing a structure-directing agent containing tetraethylammonium, a silica source, and water; and adding the mixture liquid to a surface of the zinc-doped zeolite to perform hydrothermal synthesis.
