Abstract:
Process for producing alkene(s) from a feedstock containing at least one monohydric aliphatic paraffinic alcohol having from 2 to 5 carbon atoms. The process is carried out by 1 converting the monohydric aliphatic paraffinic alcohol(s) containing 2 to 5 carbon atoms in a reactive distillation column at elevated pressure and temperature into a heads stream having 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 into alkene(s) and ether(s), and 5 recycling at least part of the separated ether(s) from step 4 into the reactive distillation column. An alkene(s) stream from step 4 is then recovered.
