Beschreibung
Zusammenfassung:	Process for the production of fuels and chemicals from waste materials comprising the steps of: a) Oxidative gasification of said waste materials to produce synthesis gas; b) Cleaning of said synthesis gas; c) Production of hydrogen and oxygen streams by electrolysis of steam or water; d) Addition of the hydrogen produced in said step c) to said synthesis gas to modify its composition to achieve a desired ratio (H2-CO2/(CO+CO2); e) Use of said synthesis gas to produce methanol with the methanol synthesis and/or hydrocarbons with the Fischer - Tropsch synthesis. L'invention concerne un processus de production de combustibles et de produits chimiques à partir de déchets comprenant les étapes de : a) la gazéification par oxydation desdits déchets pour produire un gaz de synthèse ; b) le nettoyage dudit gaz de synthèse ; c) la production de flux d'hydrogène et d'oxygène par électrolyse de vapeur ou d'eau ; d) l'ajout de l'hydrogène produit dans ladite étape c) audit gaz de synthèse pour modifier sa composition pour obtenir un rapport souhaité (H2-CO2/(CO+CO2) ; e) l'utilisation dudit gaz de synthèse pour produire du méthanol avec la synthèse de méthanol et/ou des hydrocarbures avec la synthèse de Fischer-Tropsch.
