[ES] Procedimiento para la valorización de compuestos oxigenados presentes en fracciones acuosas derivadas de biomasa. La presente invención se refiere a un procedimiento para la producción de mezclas de hidrocarburos y compuestos aromáticos, para su posterior uso como componentes de combustibles (preferentemente en el rango C5-C16), mediante la transformación catalítica de compuestos oxigenados presentes en fracciones acuosas derivadas de tratamientos primarios de la biomasa, que puede comprender al menos las siguientes etapas: i) poner en contacto la mezcla acuosa conteniendo los compuestos oxigenados derivados de la biomasa con un catalizador que comprende al menos W y/o Nb, y combinaciones de Nb y W con otros elementos, ii) hacer reaccionar la mezcla con el catalizador en un reactor catalítico a temperaturas entre 50 y 450°C y presiones de 1 a 120 bares; y iii) recuperar los productos obtenidos mediante un proceso de separación líquido/líquido de las fases acuosa y orgánica.
[EN] The present invention relates to a method for producing mixtures of hydrocarbons and aromatic compounds for subsequent use as fuel components (preferably in the C5-C16 range) by catalytic conversion of the oxygenated compounds contained in aqueous fractions derived from primary biomass treatments. The method can comprise at least the following steps: (i) bringing the aqueous mixture containing the oxygenated compounds derived from biomass in contact with a catalyst which comprises at least W and/or Nb, and combinations of Nb and W with other elements; (ii) reacting the mixture with the catalyst in a catalytic reactor at temperatures from 50 to 450°C and under pressures of 1 to 120 bar; and (iii) recovering the products obtained by a liquid/liquid separation process of the aqueous and organic phases.
