<p>An olefin is prepared from an alkyl alcohol in a process, comprising the steps: a) converting the alkyl alcohol into a dialkylether over a first catalyst, to yield a dialkylether product stream containing alkyl alcohol, dialkylether and water; b) separating the dialkylether product stream into a vaporous dialkylether-rich stream and a liquid water-containing stream which water-containing stream comprises at most 5 %wt of alkyl alcohol, based on the total weight of water and alkyl alcohol; and c) converting the vaporous dialkylether-rich stream to an olefin over a second catalyst, wherein the dialkylether product stream is enriched with a base.</p> |
