Use of transition metal containing small pore molecular sieve catalysts in oxygenate conversion

A method for converting starting material to olefins comprising contacting the starting material with a small pore molecular sieve catalyst under effective conditions to produce olefins, wherein the molecular sieve has been modified after synthesis by incorporation of a transition metal ion using a transition metal compound, wherein the transition metal ion is selected from the group comprising Groups VIB, VIIB, or VII or mixtures thereof.
