Abstract: A process for converting oxygenates to olefins comprising: a) feeding an oxygenate stream to a reactor; b) contacting the oxygenate stream with a molecular sieve catalyst to form products and coke on the catalyst; c) passing the products and entrained catalyst into a first gas/solid separation device to separate the products from the catalyst; d) removing the products from the first gas/solid separation device; e) passing a portion of the catalyst from the reactor to a regenerator; f) regenerating the catalyst in the regenerator by contacting it with a regeneration medium to combust the coke on the catalyst and form combustion products; and g) passing the combustion products and entrained catalyst into a second gas/solid separation device to separate the combustion products from the catalyst wherein the separation efficiency of the first gas/solid separation device is greater than the separation efficiency of the second gas/solid separation device.
