Claim:
1. A method for converting oxygenates, comprising: exposing an input fluid stream comprising an oxygenate to a catalyst comprising zeolite ITQ-55 under conversion conditions to form a converted compound comprising a dimethyl ether, olefins, aromatics, or any combination thereof, the conversion being catalyzed by the catalyst comprising zeolite ITQ-55, wherein the zeolite ITQ-55 has a framework of tetrahedral (T) atoms connected by bridging atoms, wherein the tetrahedral atom is defined by connecting the nearest T atoms in the manner described in the following Table: wherein the zeolite ITQ-55 has, in a calcined state and in an absence of defects in its crystalline matrix manifested by the presence of silanols, an empiric formula in which M is selected from the group consisting of H X is at least one chemical element of oxidation state +3, Y is at least one chemical element with oxidation state +4, wherein Y is not Si, x is a value between 0 and 0.2, inclusive, y is a value between 0 and 0.1, inclusive, g is a value between 0 and 0.5, inclusive.
