A process for manufacturing acrolein from glycerol comprising the steps of:
- subjecting glycerol to a dehydration reaction and forming acrolein, wherein the dehydration reaction is carried out in the presence of a catalyst system comprising a catalyst having the formula:
- MPxM′yOz
- wherein:
- M is selected from V, B or Al;
- M′ is an element selected from hydrogen or elements selected from Groups 1 to 16 of the Periodic Table;
- x ranges from 0.2 to 3.0, limits included;
- y ranges from 0 to 2.0, limits included, wherein when M is Al, y is not 0;
- and
- z is the amount of oxygen bound to the other elements and that corresponds to their oxidation state.
