Title (EN) METHOD FOR DEPOLYMERISING OXYGENATED POLYMER MATERIALS
(FR) PROCÉDÉ DE DÉPOLYMÉRISATION DE MATÉRIAUX POLYMÈRES OXYGÉNÉS
Abstract:
(EN) The present invention concerns a method for depolymerising oxygenated polymer materials and the use of said method in the recycling of plastic materials and the preparation of aromatic compounds that can be used as fuel, synthesis intermediates and raw materials in the construction sectors and in the petrochemical, electrical, electronic, textile, aeronautical, pharmaceutical, cosmetics and agrochemical industries. The present invention also concerns the use of aromatic compounds obtained by the method for depolymerising oxygenated polymer materials according to the invention, in the production of fuels, electronic components, plastic polymers, rubber, drugs, vitamins, cosmetic products, perfumes, food products, synthetic threads and fibres, synthetic leathers, glues, pesticides and fertilisers.
(FR) La présente invention concerne un procédé de dépolymérisation de matériaux polymères oxygénés et l'utilisation dudit procédé dans le recyclage de matériaux plastiques et la préparation de composés aromatiques pouvant être utilisés comme carburant, intermédiaires de synthèse, matières premières dans les secteurs de la construction, dans l'industrie pétrochimique, électrique, électronique, de textile, aéronautique, pharmaceutique, cosmétique, agrochimique. La présente invention concerne également l'utilisation de composés aromatiques obtenus par le procédé de dépolymérisation de matériaux polymères oxygénés selon l'invention, 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.
