(KO) 글리세롤의 반응성 기화 방법
Abrégé
(EN)
The subject of the present invention is a method for the reactive vaporization of aqueous solutions of glycerol in a fluidized bed containing a reactive solid. The method of the invention makes it possible to simultaneously vaporize an aqueous solution of glycerol, to remove the impurities that are present in this solution or that are generated during the evaporation, and to carry out the dehydration reaction of the glycerol to acrolein and/or the oxydehydration reaction of the glycerol to acrylic acid.
