Abstract: A process for converting oxygenates to olefins comprising: a) contacting an oxygenate containing stream with a molecular sieve catalyst in an oxygenate to olefins conversion reactor under oxygenate to olefins conversion conditions to form an effluent comprising olefins; b) quenching the effluent by contacting with water; and c) contacting the quenched olefin stream with a molecular sieve to remove at least a portion of the water from the quenched olefin stream wherein the molecular sieve has a dimethyl ether adsorption capacity of less than 0.1 wt %.
