A method for converting methoxy compounds, such as methanol and dimethyl ether, into olefins, preferably ethylene, by contact with catalyst specifically prepared and/or conditioned to achieve a high yield of ethylene from the quantity of methoxy compound converted. Diffusity of the catalyst is increased by reducing it to a fine particle size and reaction conditions are controled to ensure that less than 100 % of the methoxy compound fed to a fixed of such catalyst is converted so as to produce a yield of ethylene of greater than 60 %. |
