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.

(FR)
Un procédé continu d 'obtention d'acroléine par déshydratation catalytique de glycérol ou de glycérine, en présence d'un catalyseur acide, ledit procédé comprenant la régénération concomitante dudit catalyseur et étant réalisé dans un réacteur à lit fluidisé, ledit réacteur comprenant deux zones, une première zone, ou zone inférieure, dite de régénération du catalyseur dans laquelle un gaz de fluidisation comprenant de l'oxygène est introduit et une seconde zone, ou zone supérieure, dite de réaction dans lequel le glycérol ou la glycérine est introduit et converti en acroléine.
