Abstract

The invention relates to a method for preparing acrolein from propylene, consisting of a first glycerol dehydration step preformed in the presence of a gas containing propylene and, more specifically, in the presence of the reaction gas originating from the propylene to acrolein oxidation step. The inventive method enables the use, in part, of renewable raw material, while increasing acrolein production.
