Process for producing alkene(s) from a feedstock containing at least one monohydric aliphatic paraffinic primary (or secondary) alcohol(s), consisting of ethanol or propanol(s) or a mixture thereof. The process includes the steps of 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 reactive distillation column comprises essentially the alkene(s), cooling the heads stream from the first step to a temperature sufficient to condense at least part of the alkene(s) with the highest boiling point, recycling at least part of the condensed alkene(s) from the second step back into the reactive distillation column, as a reflux return, and simultaneously recovering the remaining alkene(s).
