A METHOD OF CONVERTING OXYGENATES TO OLEFINS

摘要

A method of converting an oxygenate comprising feedstock to olefins comprising: feeding an oxygenate comprising feedstock into a reactor containing an oxygenate to olefins conversion catalyst; contacting the feedstock with the catalyst at oxygenate conversion conditions to produce an effluent comprising olefins and catalyst; removing the effluent from the reactor; separating the catalyst from the effluent in a gas/solid separation device; and passing the effluent through a heat exchanger such that the flow regime of the effluent is turbulent.
