Patent ID: 8367886

Claim:
Process for the production of alkene(s) from a feedstock comprising at least one monohydric aliphatic paraffinic alcohol having from 2 to 5 carbon atoms, comprising the following steps: 1. converting the monohydric aliphatic paraffinic alcohol(s) containing 2 to 3 carbon atoms in a reactive distillation column at elevated pressure and temperature into a heads stream comprising the corresponding same carbon number alkene(s) and ether(s), 2. separating the heads stream from step 1 into an ether(s) enriched stream and an alkene(s) enriched stream, 3. recycling at least part of the ether(s) enriched stream from step 2 as a reflux return to the reactive distillation column, 4. simultaneously separating the alkene(s) enriched stream from step 2 onto alkene(s) and ether(s), 5. recycling at least part of the separated ether(s) from step 4 into said reactive distillation column, and then 6. recovering an alkene(s) stream from step 4.
