PROCESS FOR CONVERTING AN OXYGENATE INTO AN OLEFIN-CONTAINING PRODUCT, AND REACTOR SYSTEM |
摘要 |
A process for converting an oxygenate to an olefin-containing product, wherein oxygenate is contacted with an oxygenate conversion catalyst in a reactor system comprising two or more serially arranged riser reactor stages to obtain a riser reactor effluent from each stage, wherein each riser reactor stage comprises a single riser reactor or a plurality of parallel riser reactors, such that at least part of the riser reactor effluent of a preceding riser reactor stage is fed into a subsequent riser reactor stage, and wherein oxygenate is added to a plurality of the riser reactor stages; and a reactor system comprising two or more serially arranged riser reactor stages wherein the first of the two or more serially arranged riser reactor stages has a smaller total cross-sectional area than at least one of the subsequent riser reactor stages. |
