Abstract:
1. Process for the production of alkene(s) from a feedstock comprising at least one monohydric aliphatic paraffinic primary (or secondary) alcohol(s), consisting of ethanol or propanol(s) or a mixture thereof, said process comprising the following steps: 1. converting the monohydric aliphatic paraffinic primary (or secondary) alcohol(s) into the corresponding same carbon number alkene(s) in a reactive distillation column at elevated pressure and temperature so that the heads stream extracted from the top of the said reactive distillation column comprises essentially the said alkene(s), 2. cooling the heads stream from step 1 to a temperature sufficient to condense at least part of the alkene(s) with the highest boiling point, 3. recycling at least part of the condensed alkene(s) from step 2 back into the said reactive distillation column, as a reflux return, 4. simultaneously recovering the remaining alkene(s).
