A process for the conversion of lignin to chemical precursors is presented. The process comprises treating the lignin to form less acidic compounds. The process includes reacting lignin with a hydrogenation catalyst under a hydrogen atmosphere to convert acidic oxygenate compounds to less acidic oxygenates or hydrocarbons. The oxygenate compounds are reacted in a dehydrogenation and deoxygenation process to remove the oxygen and to convert the cyclic hydrocarbons back to aromatic compounds.
Cette invention concerne un procédé de conversion de lignine en précurseurs chimiques. Le procédé comprend le traitement de la lignine pour former des composés moins acides. Le procédé comprend la réaction de la lignine avec un catalyseur d'hydrogénation dans une atmosphère d'hydrogène pour convertir les oxygénats acides en oxygénats moins acides ou hydrocarbures. Les oxygénats sont mis en réaction dans un procédé de déshydrogénation et de désoxygénation destiné à éliminer l'oxygène et à reconvertir les hydrocarbures cycliques en composés aromatiques.
