Abstract[English]
A method of purifying a biomass based composition comprising ethylene glycol, the method comprising: (a) providing the biomass based composition comprising water in an amount of at least 0.1 wt.%, based on the weight of the biomass based composition; and (b) contacting the biomass based composition with a solid acid catalyst and contacting the biomass based composition with an aldehyde removal resin to provide a purified biomass based composition.[French]
L'invention concerne un procédé de purification d'une composition à base de biomasse comprenant de l'éthylène glycol, le procédé comprenant : (a) l'obtention de la composition à base de biomasse comprenant de l'eau en une quantité d'au moins 0,1 % en poids, sur la base du poids de la composition à base de biomasse ; et (b) la mise en contact de la composition à base de biomasse avec un catalyseur acide solide et la mise en contact de la composition à base de biomasse avec une résine d'élimination d'aldéhyde pour obtenir une composition à base de biomasse purifiée.
