Title (EN) METHOD OF DEPOLYMERIZING LIGNIN
(FR) PROCEDE DE DEPOLYMERISATION DE LA LIGNINE
Abstract:
(EN) The invention relates to a method of depolymerizing lignin and to the use of this method in the production of fuels, electronic components, plastic polymers, rubber, medicines, vitamins, cosmetic products, perfumes, foodstuffs, synthetic threads and fibres, synthetic leathers, adhesives, pesticides and fertilizers. It also relates to a method of producing fuels, electronic components, plastic polymers, rubber, medicines, vitamins, cosmetic products, perfumes, foodstuffs, synthetic threads and fibres, synthetic leathers, adhesives, pesticides and fertilizers, comprising a step of depolymerizing lignin using the method according to the invention.
(FR) La présente invention concerne un procédé de dépolymérisation de la lignine et l'utilisation de ce procédé dans la fabrication de combustibles, de composants électroniques, de polymères plastiques, de caoutchouc, de médicaments, de vitamines, de produits cosmétiques, de parfums, de produits alimentaires, de fils et fibres synthétiques, de cuirs synthétiques, de colles, de pesticides, d'engrais. Elle concerne également un procédé de fabrication de combustibles, de composants électroniques, de polymères plastiques, de caoutchouc, de médicaments, de vitamines, de produits cosmétiques, de parfums, de produits alimentaires, de fils et fibres synthétiques, de cuirs synthétiques, de colles, de pesticides, d'engrais, comprenant une étape de dépolymérisation de la lignine par le procédé selon l'invention.
