Abstract[English]
Process for converting a liquid feedstock based on hydroxypropanoic acid into acrylic acid, comprising the following steps: a) a step of dispersing said liquid feedstock in "n" tubes, where n≥2, so as to obtain a feedstock in the form of droplets with an average diameter of less than 1 mm; b) a step of vaporizing said liquid feedstock in the form of droplets in "n" tubes, where n≥2, by bringing said feedstock into contact with a hot gas at a temperature of between 350°C and less than 550°C in order to obtain a gaseous mixture; c) a step of transferring said gaseous mixture to step d) in a downward flow for a period of time of less than 20 seconds; d) a step of catalytically dehydrating the gaseous mixture from step c).[French]
Procédé de conversion d'une charge liquide à base d'acide hydroxypropanoïque en acide acrylique, comprenant les étapes suivantes : a) une étape de dispersion de ladite charge liquide dans "n" tubes, où n ≥ 2, de manière à obtenir une charge sous forme de gouttelettes de diamètre moyen inférieur à 1 mm ; b) une étape de vaporisation de ladite charge liquide sous forme de gouttelettes dans "n" tubes, où n ≥ 2, par mise en contact de ladite charge avec un gaz chaud à une température comprise entre 350 °C et moins de 550 °C pour obtenir un mélange gazeux ; c) une étape de transfert dudit mélange gazeux à l'étape d) dans un flux descendant pendant une durée inférieure à 20 secondes ; d) une étape de déshydratation catalytique du mélange gazeux issu de l'étape c).
