PROCESS FOR THE PREPARATION OF OLEFINS |
摘要 |
<p>A process for the preparation of an olefin product, which process comprises the steps of: a) converting a first oxygenate feedstock in an oxygenate-to-olefins conversion system, comprising a first reaction zone in which a first oxygenate feedstock is contacted with a non-zeolitic oxygenate conversion catalyst under first oxygenate conversion conditions, to obtain a first conversion effluent comprising lower olefins and heavy hydrocarbons; b) separating the first conversion effluent into a lower olefin stream and a heavy hydrocarbon stream; and c) feeding the heavy hydrocarbon stream to a separate reactor comprising a second reaction zone in which a second oxygenate feedstock is contacted with a second oxygenate conversion catalyst under second oxygenate conversion conditions, to obtain a second conversion effluent comprising additional lower olefins.</p> |
