Abstract[English]
The invention relates to a photocatalytic flow method for the selective fragmentation of lignin, comprising:
(i) immobilising a photocatalyst on a support forming a bed, and introducing the support with the immobilised photocatalyst into a column that is transparent to radiation; (ii) and continuously circulating a lignin solution through the column packed with the bed, under illumination, to cause the fragmentation of the lignin, yielding vanillin and syringaldehyde, and such that the method is carried out continuously.[Spanish]
Método fotocatalítico de flujo para la fragmentación selectiva de lignina que comprende: (i) inmovilizar un fotocatalizador sobre un soporte formando un lecho, e introducir el soporte con el fotocatalizador inmovilizado dentro de una columna transparente a la radiación, (ii) y hacer circular de forma continua una disolución de lignina a través de la columna cargada con el lecho, bajo iluminación, para provocar la fragmentación de la lignina, obteniendo vainillina y siringaldehído, y tal que el método se lleva a cabo en continuo.[French]
Procédé photocatalytique de flux pour la fragmentation sélective de lignine qui consiste à : (i) immobiliser un photocatalyseur sur un support formant un lit, et introduire le support avec le photocatalyseur immobilisé dans une colonne transparente au rayonnement, (ii) et faire circuler de manière continue une dissolution de lignine à travers la colonne chargée avec le lit, sous éclairage, afin de provoquer la fragmentation de la lignine, pour obtenir de la vanilline et le syringaldéhyde, et de manière que le procédé s'effectue en continu.
