ABSTRACT:
Process for the production of alkenes from a feedstock comprising monohydric aliphatic paraffinic alcohols having from 2 to 3 carbon atoms, in which the monohydric aliphatic paraffinic alcohols containing 2 to 3 carbon atoms are dehydrated into the corresponding same carbon number alkenes at a pressure of more than 0.5 MPa but less than 4.0 MPa and at a temperature of less than 300° C. The alcohols present in the feedstock comprise ethanol, propanol(s), less than 1 wt % of methanol and less than 1 wt % of C3+ alcohols.
