Title
(EN) Process for obtaining acrolein by catalytic dehydration of glycerol or glycerin
Abstract
(EN)

A continuous process for obtaining acrolein by catalytic dehydration of glycerol or glycerin, in the presence of an acid catalyst, wherein said process comprises the concomitant regeneration of said catalyst and is carried out in a fluidized bed reactor, said reactor comprising two zones, a first zone, or lower zone, termed catalyst regeneration zone, in which a fluidization gas comprising oxygen is introduced, and a second zone, or upper zone, termed reaction zone, in which the glycerol or glycerin is introduced and converted into acrolein.
